The following is a list of all episodes of Only Murders in the Building.
Season 1[]
True Crime[]
Charles-Haden Savage, a misanthropic former television actor; Oliver Putnam, a struggling Broadway director; and Mabel Mora, an apartment renovator, live in the Arconia. By chance, the three of them meet on an elevator, joined by Tim Kono on the phone. Later, after evacuating the building for an alarm, they bond over their shared love of a certain true-crime podcast. They learn that there was a death in the Arconia and sneak back inside to see Tim dead. The investigators believe it was suicide, but the three think otherwise; they find more and more evidence, such as Tim's frantic phone call on the elevator and a package addressed to him that contained an engagement ring. Meanwhile, Oliver struggles with his relationship with his son, Charles discusses his need for solitude, and Mabel expresses her fear of getting personal with people. They start a podcast titled Only Murders in the Building as they continue to investigate. An old photo is shown of Mabel and the friends she dubbed "My Hardy Boys", which unexpectedly includes Tim. The episode begins with a flashforward set two months after the trio's first meeting in which Charles and Oliver find Mabel kneeling over a dead body.
Who Is Tim Kono?[]
Charles and Oliver try to learn more about who Tim was, and along with Mabel, they attend a memorial service for him. It is revealed that he was unpopular among many Arconia residents and had several complaints filed against him, with the most prominent emotion expressed being relief that the death of the asthmatic Tim allows the building to reopen the apartments' fireplaces. The trio goes into Tim's apartment to find more clues, but their lack of trust in one another makes things tense. Mabel privately records a video that reveals that she has known Tim since they were children, bonding over The Hardy Boys books and solving pretend mysteries together. As they grew older, they added new friends Oscar and Zoe. One night, 10 years earlier, the four attended a New Year's Eve party on the roof of the building, and Zoe was later found dead. As he and Zoe had been arguing earlier in the evening, Oscar was arrested for her murder, but Tim told Mabel that he had seen someone else fighting with Zoe before she died. He did not disclose this to the police, causing a rift between him and Mabel. Later, Mabel revisits Tim's apartment and finds a cache of jewelry and some of her old drawings.
How Well Do You Know Your Neighbors?[]
Charles, Oliver, and Mabel all think Howard is a prime suspect, as they found his cat's paw prints in Tim's blood. Bunny threatens to evict Oliver if he does not pay his building fees. He goes to his old associate Teddy, begging for money; after initially refusing, Teddy agrees to sponsor the podcast. Later, Oliver sees Sting in the elevator and thinks he may also be a suspect. Mabel comes across a note from Tim detailing a meeting in one week with somebody identified only as "G.M." Oliver discovers a threatening note on his door and that Winnie, his bulldog, has been poisoned, presumably by the same perpetrator.
The Sting[]
Oliver suspects that Sting poisoned Winnie and enlists the help of Charles and Mabel to prove he is guilty of both Winnie's poisoning and Tim's murder. After consulting Cinda Canning, the host of their favorite podcast, the trio presents Sting with a turkey and question him about Tim, revealed to be Sting's former stockbroker. Sting guiltily confesses that, after Tim lost a substantial sum of his money, he angrily fired Tim and told him to kill himself, but is relieved when the trio announces that they believe Tim's death was murder, not suicide. Meanwhile, Charles goes on a date with Jan. It is a disaster, but she agrees to a second date when Charles later shares a personal story with her. Mabel finds a connection to the jewelry she found in Tim's apartment and Oliver's son, Will, reveals that he remembers Mabel from their youth and her connection to Tim. A flash forward to a few months later reveals that Charles, Oliver, and Mabel are the subject of Cinda Canning's new podcast, Only Murderers in the Building.
Twist[]
Mabel is being followed by "Tie-Dye Guy", who turns out to be her old friend Oscar, recently released from prison for Zoe's murder. He offers to drive her wherever she is going, which turns out to be Bayport, New York, on Long Island. Charles and Oliver see Mabel leaving the Arconia, so they follow her to Bayport. They end up in a tattoo parlor there, where Mabel finally admits that she knew Tim. Oscar admits that he is "Tie-Dye Guy", but says he did not murder Tim; he was, however, outside Tim's door when he heard a gunshot.
To Protect and Serve[]
Oscar and Mabel appear to have feelings for each other. Mabel's mother does not want her involved in Tim's murder investigation, but Mabel asserts her independence on this matter. Detective Williams starts having second thoughts about closing Tim's case too quickly, so she surreptitiously gives Mabel Tim's phone. Teddy is thrilled that his business is mentioned on Jimmy Fallon's show, and writes Charles and Oliver a check for $50,000. Charles notices that the check is drawn from an "Angel" account, which is the name of the person that Tim had been dealing with for jewelry.
The Boy from 6B[]
(editor note: the episode has no dialogue as it is from the perspective of a deaf man)
Teddy's son Theo spies on the trio and breaks in to take photos of their suspect board, relaying to his father that the podcast is on to them, but Teddy dismisses the concerns. Charles and Mabel break into Teddy's apartment and discover a secret room of urns from a funeral home. They narrowly avoid Theo, who later notices a rubber glove they left behind. While Oliver and Mabel leave to investigate the funeral home, Charles has a date with Jan. At the funeral home, the two discover a secret room with jewelry. Theo is working there and stealing items off the bodies, and soon notices Oliver and Mabel. Flashbacks reveal that Theo had a crush on Zoe, who noticed and communicated back in ASL. Another flashback reveals Theo spying as Zoe takes a ring from Teddy's apartment, which Teddy notices during the New Year's Eve party. After an argument, Theo accidentally pushes Zoe off the roof. Tim is the only witness, but an implied death threat from Teddy silences him. Theo has kidnapped Oliver and Mabel back in the present, driving them to an unknown location, but not before they send texts to Charles telling him the password to Tim's phone might be "THEO".
Fan Fiction[]
Teddy returns Mabel and Oliver to the Arconia on the condition that they end the podcast and absolve the Dimas family of suspicion. Back at the building, Mabel and Oliver are swarmed by the "superfans" of the podcast. Detective Williams suggests the trio release all their evidence on the podcast. Oscar shares that Tim already had Zoe's green ring when he died, although its whereabouts are unknown. Desperate for a new perspective on the case, Oliver invites the podcast's superfans to help the group solve Tim's murder in time for their abrupt series finale. Charles is distracted by Jan, and Mabel and Oliver force her out of the investigation. Jan returns to her apartment, where she finds a warning note on the door that reads: "I'M WATCHING YOU". The podcast finale premieres, complete with evidence of the Dimases' crimes. Williams doubts the Dimases' involvement in the murder when Tim's autopsy reveals death by poisoning. Security footage from the fire alarm proves Teddy and Theo were not in the building. Charles visits Jan's apartment, where he finds her unconscious and bleeding.
Double Time[]
On their podcast, the trio retracts their accusation of Teddy and Theo in Tim's murder. Jan survives her stabbing and Charles helps with her recovery. Charles's former stunt double, Sazz Pataki, shows up and immediately jumps into helping the trio investigate, much to the dismay of Charles and Jan. Later, a building meeting is called to address the podcast, and the building votes to evict the trio, even after Charles says the podcast is done. Oliver and Mabel try to find a new leader to convince Charles to stay on the investigation and speculate that Tim might have had a secret girlfriend, a theory seemingly confirmed by Tim's neighbor. Charles goes to Jan's concert at Sazz's urging and sees a young female bassoonist who has replaced Jan at first chair. At the same time, Oliver and Mabel find a bassoon cleaner among Tim's stash of sex toys.
Open and Shut[]
The trio discovers that Jan is the murderer. She was romantically involved with Tim but killed him a day after they broke up. As Charles confronts Jan, he realizes she has poisoned him. Mabel and Oliver break into Jan's apartment and find a poison bottle and a box labeled "Jan's Lil' Toxins". Jan tries to gas the whole building via the newly open fireplaces, but the trio runs to the basement and stops it. In the basement, they see Jan again, who threatens to shoot them. A scuffle ensues, and Mabel knocks Jan out with the emerald ring. Jan is arrested. Later, as the trio celebrates, Mabel goes to get more champagne, and Oliver and Charles receive a mysterious text message telling them to leave the building immediately. The scene that opened the series is repeated, as Oliver and Charles run to Mabel and find her hunched over Bunny's dead body, covered in blood. The trio is led out of the Arconia in handcuffs while the Arconia tenants and others, including Detective Williams, Oscar, and Cinda, watch.
Season 2[]
Persons of Interest[]
Charles, Oliver, and Mabel are arrested and interviewed by Detective Williams and Detective Kreps before being released due to lack of evidence. Mabel suggests they follow the police's advice and stay away from the case. Later, a woman named Alice invites Mabel to an art show at a local gallery and encourages her to pursue art again. Oliver meets Amy Schumer, who has moved into Sting's apartment, and she proposes to turn the podcast into a TV series. Meanwhile, Charles is approached to play "Uncle Brazzos" in a Brazzos reboot. The trio discovers that Cinda has started a podcast about them, encouraging them to investigate to clear their names. Mabel reveals Bunny said "14" to her before she died. The trio breaks into Bunny's apartment and discovers her pet parrot mimicking Bunny. When Howard and Uma walk in, the three hide and overhear them panic over a painting missing from Bunny's apartment. Sneaking away through a hidden elevator, they return to their apartments, and Charles discovers the missing painting on his wall.
Framed[]
Charles realizes one of the people in the painting is his father, while Mabel reveals Bunny also said "Savage" to her before she died. At Howard's invitation, the trio attends a memorial for Bunny, planning to return the painting to Bunny's apartment. There, they meet Leonora Folger, Bunny's mother and the painting's owner. Oliver and Mabel intend to sneak the painting up the hidden elevator into Bunny's apartment, planning to meet Charles outside, but Charles accidentally lets the elevator door close, locking them out. In a panic, they stash the painting near a dumpster but later find it missing. Mabel returns to the art studio, where Alice encourages her to smash art to release her emotions, and they eventually kiss. Oliver meets with Amy in her apartment and discovers that she found the painting by the dumpster and hung it on her wall. Leonora talks to Charles about the painting, causing him to remember a day from his childhood when his father was arrested. Leonora learns the painting is at Amy's but upon inspection, declares it a fake. Bunny's parrot is delivered to Oliver as per Bunny's will, and the bird says "I know who did it."
The Last Day of Bunny Folger[]
The trio tries to find out what Bunny's last day was like before she died. In a flashback, it is revealed that it was Bunny's last day as board president and that she considered moving to Florida after retiring. She received a call from a mysterious person who wanted to buy her painting, but rejected the offer. She also gave present money to her regular café server, Ivan, and easily fixed the Arconia's main elevator when she, Charles, and Mabel got stuck in it. At the end of the day, she realized how much the Arconia meant to her and decided not to retire, upsetting her successor, Nina Lin, who openly threatened her for not stepping down. Later, Bunny visited Charles, Oliver, and Mabel, offering a bottle of champagne in hopes of joining their celebration, but they thought she was just stopping by and did not invite her in. A masked and gloved figure attacked her when she returned to her apartment. The trio feels guilty that they could have saved Bunny's life "with a simple act of kindness." They realize Nina had a motive to kill Bunny, making her their prime suspect.
Here's Looking at You[]
Lucy, the teenage daughter of Charles's ex-girlfriend, unexpectedly shows up at his apartment. She reveals to Charles, Oliver, and Mabel that she discovered secret tunnels inside the walls of the Arconia years earlier. As they walk through the tunnels, they overhear Nina and her husband agreeing that Bunny had to go so that the Arconia could be modernized. Oliver also witnesses an argument between Teddy and Theo Dimas, who have been released on parole, which makes Oliver reevaluate his relationship with his son. Later, the trio and Lucy visit Nina to get her to confess to Bunny's murder, but she goes into labor and begs them to find Bunny's killer. Lucy confesses to Charles that she ran away from home after her mother remarried. Though touched by Lucy's words that he is the best stepfather she ever had, Charles insists she go home. Before leaving, Lucy warns Charles that he is in danger, but does not tell him that she came to the Arconia on the night of Bunny's murder and saw the killer escaping through the tunnels. Charles visits Jan in prison to ask for her help.
The Tell[]
Jan tells Charles that the killer is possibly an artist since they composed the crime scene to frame Mabel. Charles and Oliver learn that Mabel is dating Alice, who is an artist, and become suspicious of her. At a party Alice hosts for an eclectic art crowd, Oliver proposes a murder game called Son of Sam. By the end of the game, he declares Alice the murderer and asks a multitude of probing questions, forcing her to reveal that she lied about her background and her studies so people would think she is a legitimate artist. Later, they learn that Bunny had a meeting with someone in her regular diner the day before she died about the Rose Cooper painting. Alice apologizes to Mabel for lying to her, and the two reconcile by sharing personal secrets. Meanwhile, Will takes a DNA test for his son's school project, which reveals that he has Greek ancestry despite Oliver's Irish heritage. Oliver sadly speculates that his ex-wife may have had an affair with Teddy who might be Will's biological father.
Performance Review[]
The trio wants Detective Williams's help with a fingerprinted matchbook they recently found, but she is on maternity leave. When they receive a text message in her name to leave their evidence in a public place, they fear it is the killer trying to get their hands on the evidence. They decide to leave a glitter bomb instead to catch the killer, but their personal problems distract them during the waiting until they miss their opportunity. Meanwhile, Cinda finds a man from Mabel's past who falsely claims that Mabel cut off one of his fingers, and she wants to use this in her podcast. Cinda's assistant, Poppy, has second thoughts about that, and reveals some hidden truths about Cinda to Mabel. Mabel goes to Alice's studio, where she finds Alice recreating the scene of Bunny's murder for an art exhibit. Heartbroken, Mabel runs off, but sees a glitter-bombed person in her subway car. Later, Charles and Oliver see an Internet video of Mabel seemingly stabbing that person.
Flipping the Pieces[]
A series of flashbacks details Mabel's relationship with her father before his death from cancer. Following the subway incident, Mabel wakes up in Theo's apartment with no memory of the attack and her bag missing. Theo explains to her that he was in the subway car too, saw what happened, and brought Mabel home after she passed out. He shows Mabel an employee badge from Coney Island that her assailant dropped, so they go there to investigate. Mabel recovers her bag before her assailant discovers her, but finds the matchbook gone. Meanwhile, Detective Williams visits Charles and Oliver, who reveal that they have the murder knife, which they give her for analysis. After fleeing Coney Island, Mabel forgives Theo for Zoe's death and remembers the night of Bunny's murder, realizing she saw someone escaping from her apartment. Reuniting with Charles and Oliver, Mabel shows Charles a picture of Lucy she found in her bag. Fearing Lucy is the killer's next target, Charles tries to call her, but the call is cut off when a blackout hits the city.
Hello, Darkness[]
Knowing that Lucy is alone in Charles's apartment, the trio races back to the Arconia to save her from the killer. Meanwhile, the blackout forces the Arconia's residents to make new connections. Howard hangs out with one of his neighbors, whom he has a crush on, and eventually asks him out, despite the man's lethal allergy to cats. Concurrently, Lester, the doorman, helps Nina assemble a baby swing, during which Nina evaluates Lester's job and gives him a promotion. The trio discover that someone broke into Charles's apartment and chased Lucy through the secret tunnels. They later encounter Marv in the tunnels, believing he is the killer, but in reality Marv wanted to help the trio catch the killer yet unintentionally scared them away with his presence. At Marv's request, Oliver agrees to record him for a podcast episode while Lucy finally tells Charles what she saw on the night of Bunny's murder. After the power returns, the trio meets Detective Kreps in the building. Mabel notices some glitter on his neck and realizes he was her assailant.
Sparring Partners[]
Mabel tries to confront Kreps about his involvement in Bunny's murder. He denies everything, but mentions his admiration for Cinda's podcasts, heightening Mabel's suspicion. Meanwhile, Charles and Oliver discover the original Rose Cooper painting hidden under the cage of Bunny's parrot. Charles further discovers that Leonora is Rose Cooper herself. She reveals to Charles that she and his father were lovers for years and he was arrested as a result of trying to defend her from her enraged husband. She also shows Charles another painting hidden in the canvas, depicting young Charles and his father. Concurrently, Oliver learns that Teddy is indeed Will's biological father, but, for Will's sake, they both decide to keep this a secret. Alice gives Mabel a jigsaw puzzle as a peace offering, and with its help, Mabel realizes that one of Cinda's podcasts mentioned a restaurant with the logo she saw on Kreps's backpack. When she questions Poppy about this, she reveals she is Becky Butler, the subject of the podcast, and that Kreps is Cinda's lover who helped Cinda provide evidence about her case. Mabel concludes that Cinda is the true mastermind behind Bunny's murder.
I Know Who Did It[]
The trio stages a killer reveal party where they endeavor to induce Bunny's killer to confess. After failing with Cinda, Mabel declares Alice the killer, which seems to be true when Alice stabs Charles in the stomach. Cinda praises Mabel for solving the case, which makes Becky so frustrated she unwittingly reveals information only the killer would know. As Charles wakes up unharmed, the guests reveal the party was an act to expose Becky as the real killer. Detective Williams found the murder knife had Becky's DNA on it and Mabel realized Bunny said "14 Sandwich" to her, which was Becky's favorite meal at Bunny's regular diner. Becky is arrested along with Kreps, who is revealed to be Becky's lover and accomplice. Their motive was to gain recognition and a higher salary in their respective jobs by solving a premeditated murder. With the case closed, Charles gets a proper role in the Brazzos reboot; Mabel and Alice resume their relationship; and Oliver reconciles with his son, who already knows they are not biologically related. One year later, on the opening night of a Broadway play Oliver directed, the lead actor, Ben Glenroy, suddenly collapses on stage during his performance.
Season 3[]
The Show Must...[]
At an audition for Oliver's murder mystery play Death Rattle, a struggling actress, Loretta Durkin, amazes him with her performance. Four months later, at the play's read-through, the cast and crew meet for the first time, including Howard as Oliver's assistant, Charles in a supporting role, and Ben Glenroy in the lead role. Loretta fails to deliver her lines convincingly, so Ben urges Oliver to fire her, but Oliver is convinced of Loretta's talent. In the present, Ben is pronounced dead by the authorities after collapsing on stage. At the play's planned after-party, Mabel floats the theory to Oliver that Ben was poisoned and proposes a new podcast. A revived Ben appears at the party, attributing his clinical death to food poisoning. He gives a phony apology to everyone for his arrogant behavior over the last few months, but veiledly insults Loretta again. Afterward, Mabel tells Charles and Oliver that her aunt sold her apartment, so she is moving out of the Arconia in a month. As they take the elevator, Ben's dead body suddenly crashes down in front of them.
The Beat Goes On[]
At Ben's funeral, Mabel and Charles meet Gregg, who claims to have worked for Ben as a security guard. Instead, Gregg is revealed to be an obsessed fan of Ben's, and kidnaps them. In Gregg's custody, Mabel tells Charles that Ben's murder is personal to her because one of his shows helped her overcome her father's death, while Charles reveals that the tension between him and Ben stemmed from when he unintentionally got Ben fired from Brazzos years earlier. Gregg intends to torture the pair into confessing to Ben's murder, but Detective Biswas arrives with the police and arrests him as Ben's killer based on Gregg's obsession and his whereabouts at the time of the murder. Mabel, however, theorizes that since Gregg had Ben's handkerchief from the play and the body was found holding an identical one, Gregg could not have committed the murder. She and Charles agree to begin a third podcast to find Ben's real killer, about which Oliver is reluctant. Following a minor heart attack he suffered after encountering a critic who was planning to pan his play, he becomes inspired to turn the show into a musical.
Grab Your Hankies[]
Charles attempts to find out which cast member lost their handkerchief, believing that one could be the killer. Concurrently, Mabel goes to Ben's apartment looking for clues and meets Tobert, Ben's documentarian. They are forced to hide when Dickie, Ben's brother and manager, enters the apartment, during which Tobert reveals he intends to make a documentary about Ben's murder and that he has footage of Ben before he collapsed on stage. Meanwhile, Loretta tells Oliver she has won a television series role in Los Angeles that begins shooting next week. Not wanting to lose her, Oliver reminds her that she is under contract, but later agrees to let her go if she performs her character's lullaby for the producers, Donna and Cliff. Amazed by her performance, they agree to fund Death Rattle Dazzle, prompting Loretta to stay as well, and she and Oliver kiss. Tobert shows Mabel footage of Ben in his dressing room talking to someone off camera. At the same time, Charles discovers that cast member Kimber, who plays Ben's love interest, lost her handkerchief.
The White Room[]
The trio suspects that Kimber killed Ben due to an affair gone awry between them. Kimber, however, tells Mabel she only wanted Ben to promote her beauty products, and when he backed out at the last minute, she sold her handkerchief. She also reveals that Ben was upset on opening night about a red mark on his face until someone in his dressing room fixed it. Charles and Oliver break into Ben's dressing room, finding "Fucking Pig" written on his mirror with lipstick. Later, Cinda approaches Mabel with a job offer, but Mabel turns it down. Meanwhile, Charles has to perform a patter song in the play, but every time he rehearses it, he enters "The White Room", a comforting place inside his mind, while his body acts disturbingly without his knowledge. Oliver thinks this is caused by the pressure of his girlfriend, Joy, moving in with him, which Charles is not ready for. When he attempts to tell her that, Charles enters The White Room again, reemerging to discover he has proposed to Joy, while she recognizes the lipstick from Ben's dressing room as her own.
Ah, Love![]
While Oliver goes on a date with Loretta, Mabel meets with Tobert at a restaurant to observe Jonathan, Ben's understudy and Howard's boyfriend. They see him exchanging something with a man, whom Tobert identifies as Ben's doctor. Meanwhile, following a fight between Charles and Joy about the lipstick, Charles is visited by Sazz, who gives him an impromptu therapy session about his relationship problems. Oliver and Loretta eat dinner at her place, but Oliver is surprised when Loretta calls Ben a "fucking pig" and confesses to him that she had a scuffle with Ben on opening night. Joy explains to Charles that she simply left her lipstick at Ben's dressing room after she fixed a mark on his face, which Charles reveals was because he punched Ben for his scuffle with Loretta. Charles also reveals that his proposal was accidental, causing Joy to break up with him. Mabel takes Tobert back to her apartment to show him her board of clues, and they kiss. Oliver and Loretta sleep together in her apartment, where he later finds a scrapbook full of news clippings about Ben.
Ghost Light[]
After Howard claims to have seen the ghost of a deceased actor at the theater, the trio goes there to investigate. Mabel and Tobert confront Jonathan about his meeting with Ben's doctor; he confesses that he obtained the same cocktail of medications Ben used to cope with the pressure of being the lead, a role he never wanted. Oliver discovers that his former director friend, Jerry, pretended to be the ghost to hide that he has been living in the theater's attic for months. He also tells Oliver about the fight between Ben, Loretta, and Charles, which he witnessed firsthand. Despite growing increasingly suspicious of Loretta, Oliver chooses to hide his suspicion from Charles and Mabel, who find him trying to scrub the lipstick. An argument erupts, in which Oliver accuses Charles of not being forthcoming about the fight, frustrating Charles into quitting the play. Oliver also accuses Mabel of sabotaging his show with her investigation, causing her to reveal Cinda's offer and vow to continue investigating on her own.
CoBro[]
Charles discovers that Uma stole the handkerchief from Ben's corpse; however, she sells it to an unknown buyer before he can retrieve it. Meanwhile, Oliver replaces Charles with Matthew Broderick, but soon fires him and rehires Charles after growing annoyed with Broderick's method acting antics. Elsewhere, Mabel learns from Dickie that he was adopted before his parents conceived Ben and that he was always overshadowed by Ben's success despite doing most of the work for it. Finding an old drawing of CoBro, Ben's most famous role, and looking at the signature below, Mabel theorizes with Tobert and Theo that Dickie could have created the character, giving him a motive to kill. Oliver shows Charles the scrapbook he stole from Loretta, and they decide to give it to Mabel, only to learn that Mabel has already moved out of her apartment and that she started the podcast's new season without them. Listening to the first episode, which details evidence that Gregg is not the killer, Detective Biswas decides to reopen Ben's case.
Sitzprobe[]
Flashbacks reveal that Dickie is Loretta's biological son, whom she gave up for adoption to pursue her acting career. Nonetheless, she had always kept tabs on him by collecting news about him and Ben, and upon learning their involvement in Oliver's play, she auditioned for a role to be reunited with him. At the musical's sitzprobe, she decides to tell Dickie the truth in a letter, but the police arrive and lock down the theater, saying the killer is someone from the cast or crew. The trio make amends with each other and decide to work together again to find the killer. While Charles and Oliver secretly record Detective Williams's interrogations of the cast, Mabel helps Howard reassemble a shredded document that might be a clue. Loretta learns that the police and the trio suspect Dickie as the killer, which she refuses to believe. Charles and Mabel find Loretta's letter, while Oliver returns the scrapbook to her and confesses his love for her. During her rehearsal on stage, Loretta sees the police approaching Dickie, so she confesses to Ben's murder to save him. As she is led out of the theater in handcuffs, Oliver suffers another heart attack and collapses.
Thirty[]
Following Oliver's recovery, the trio learns that Dickie has an alibi for the time of Ben's murder. Using their knowledge and the clues they already obtained, they recreate the last 30 minutes before Ben collapsed on stage: Ben arrived late to the theater after being with his seamstress friends, who helped him make the handkerchiefs he presented to the cast and crew. Later, he overheard Loretta encouraging Dickie to quit as his manager due to the stress he was under, resulting in a fallout between the brothers and the fight between Ben, Charles, and Loretta. An upset Ben then fired Tobert and retreated to his dressing room, where he ate a cookie and wrote "Fucking Pig" on his mirror out of guilt for ruining his diet. Howard gives the trio the reassembled document, which turns out to be an early negative review of Ben's performance. The trio reaches the conclusion that Donna poisoned Ben to prevent the show and Cliff's career from being ruined. They run into the court to stop Loretta from pleading guilty, only to learn that Donna is among the witnesses.
Opening Night[]
After Loretta receives the missing handkerchief from Dickie, the trio uses it as evidence to force a confession out of Donna on the opening night of Death Rattle Dazzle. To their surprise, she readily confesses to Ben's murder but asks to see the play before she is arrested. Oliver takes the lead role when Jonathan cannot perform, having taken too much anti-anxiety medication, and Loretta finally tells Dickie she is his biological mother. Mabel notices Cliff going to the theater's attic after a conversation with Donna, and confronts him upon realizing he pushed Ben down the elevator shaft. A guilt-ridden Cliff insists it was an accident and attempts to commit suicide by jumping from above the stage but is stopped and comforted by Donna. The two are taken into custody as the show ends with a success. At the play's after-party, Dickie, Loretta, and Tobert reveal they all have upcoming gigs in Los Angeles, but the trio decide to stay in New York. Sazz comes to celebrate and tells Charles they need to talk before entering Charles's apartment, where she is shot by an unknown assailant.
Season 4[]
Once Upon a Time in the West[]
After finishing the podcast's latest season, the trio goes to Charles's apartment to celebrate, unaware of Sazz's murder as the body has already disappeared. The next morning, Charles texts Sazz and receives a reply that she had to fly to L.A. to double for Scott Bakula. The trio is approached by Bev Melon of Paramount Pictures with a proposal for a film adaptation of their podcast, and they fly to L.A. to discuss the deal. At a party thrown by the studio, they meet the actors who will play them: Eugene Levy, Zach Galifianakis, and Eva Longoria. Mabel is reluctant, but Eva advises to use the money for her life rights to build something on her own. Charles runs into Bakula, who says Sazz never showed up on set, and upon visiting her Hollywood apartment, the trio finds miscellaneous notes revolving around Charles. Returning to New York, they discover blood prints and a bullet hole in Charles's window before finding Sazz's ashes and prosthetic parts in the Arconia's incinerator, while the person texting in Sazz's name sends them an open threat.
Gates of Heaven[]
Suspecting the shot that killed Sazz came from one of the apartments on the west side of the Arconia, Oliver and Mabel investigate some of its residents. They meet Vince Fish, a friendly eyepatch-wearing man, and a Hispanic family of three, Alfonzo, Inez, and Ana, who invite them to a card game called Oh Hell and tell them about an always locked apartment belonging to someone only known as "Dudenoff". Mabel discovers that one of Sazz's notes contains the code numbers for the apartment's lockbox, so they break in and find a pig in the bathtub and a ham radio. Meanwhile, as Charles mourns Sazz, he is visited by Jan, who broke out of prison and tells him that Sazz was poking around the building recently, fearing that another murderer might be targeting Charles. Jan escapes before the police arrive for her, and Charles reports Sazz's murder to them. While they investigate the incinerator, the trio uses luminol to locate where Sazz's body fell. They find she wrote "Tap in" on the floor with her blood as an encouragement for Charles to solve the murder, while Oliver realizes the code numbers spell "Oh Hell" upside down.
Two for the Road[]
With the FBI taking over Sazz's case, Detective Williams decides to help the trio's investigation, giving them information about the gun the sniper used. Concurrently, Eugene, Zach, and Eva arrive to study the trio's characteristics for the film. Spending the day with Oliver, Zach views him only as a narcissist until Howard tells him about Oliver's fighting spirit despite his failures, giving Zach a new perspective on the character's depth. Meanwhile, Mabel and Eva investigate Rudy Thurber, a Christmas-loving resident, after finding a piece of tinsel in Dudenoff's apartment. Under Eva's provocation, Rudy admits he actually hates Christmas, uses the theme only for his bodybuilder videos, and reveals that the piece they have found is not tinsel as it is non-flammable. Elsewhere, Charles and Eugene discover that Vince has a group photo of his neighbors, one of whom is holding a pig and has their face crossed out. Mabel decides to use squatter's rights to stay in Dudenoff's apartment and force them to come back. Later, the trio discovers a frequency on the ham radio and makes contact with someone who warns them to stop their investigation.
The Stunt Man[]
The trio learns that Sazz visited a bar for stunt performers on the night of her murder, so they go there to ask some questions. With the help of Glen Stubbins, Ben Glenroy's former stunt double, Charles meets the bar's chiropractor, Dr. Maggie, who tells him that Sazz was planning to retire from stunt working. Meanwhile, after attempting to evict Mabel from Dudenoff's apartment, the residents of the West Tower confess to her that they are illegal tenants as all the west apartments are rented by Professor Milton Dudenoff, who resides in Portugal, but lets them live in the Arconia for $200 a month. They also reveal the person who warned the trio on the ham radio was just Rudy's paranoid ex-girlfriend, Helga, and that none of them had ever met Sazz. Charles performs as Sazz's double so that her stunt double friends can hold a proper funeral for her, and remembers Sazz's dream of opening a training camp for stunt performers after her retirement. As the trio goes to the location Sazz wanted for the camp, they are surprised to find Bev there, who points a gun at them.
Adaptation[]
Bev explains to the trio that she was trying to investigate Sazz's death because Sazz left her an unsettling voicemail about a problem with the film. Suspecting the killer is someone on the film, the trio interrogates screenwriter Marshall P. Pope, who is revealed to have been faking his appearance to look more like a credible writer. Marshall proves he has an alibi for the night of the murder and questions Charles's theory that the murder and the disposal of the crime scene could be done in 12 minutes. After Oliver fails to reenact the murder in that amount of time, Mabel discovers that, on the photos they took of the film crew, someone has the same shoeprint they saw in Dudenoff's apartment. On a photoshoot with the cast and crew, Eva helps the trio set a trap with tacky mats so that the shoeprints can be visible, while Charles realizes the murder is, in fact, feasible in 12 minutes if two people are involved. As the trio discovers that directors Tawny and Trina Brothers have the shoeprints they are searching for, the lights suddenly go out and a gun is fired.
Blow-Up[]
Zach and Glen are shot and hospitalized. Consequently, the trio deduces that Oliver was the intended target and that the killer is after the three of them. Detective Williams informs them that Dudenoff is not in Portugal, and they learn that he was the film professor of the Brothers sisters. Williams sends Sazz's remains to Charles, who discovers there are two left shoulder joints in the box, leading them to believe that there was another murder in the building, which Sazz could have found out. The trio confronts the Brothers sisters, who admit that they were in Dudenoff's apartment on the night of Sazz's murder, but only to visit him and to place hidden cameras in the building for behind-the-scenes footage of the film. They are shocked when Mabel reveals that, according to Williams's identification, the other shoulder joint was Dudenoff's. The trio later simultaneously receives "I'm watching you" text messages from Sazz's phone and footage of themselves from the last few days. Realizing the killer has been monitoring their every move, they leave the Arconia in fear to find a safe place.
Valley of the Dolls[]
The trio hides on Long Island at the home of Doreen, Charles's sister. Bev and the actors visit them, much to the chagrin of Mabel, who wants to focus on the case. Loretta also visits and ends up in a brawl with Doreen due to the latter's crush on Oliver and her distress about her estrangement from Charles. While Doreen and Charles make amends, promising to visit each other more often, Loretta and Oliver talk about the future of their relationship, and Loretta accepts Oliver's marriage proposal. Wanting to help the investigation, the actors point out that the killer is possibly the mysterious person who left threatening letters in the Arconia throughout the podcast's first season and that the clues on Sazz's notes seem to confirm this theory. Later, Howard calls the trio and reports his discovery that the West Tower residents are individually cashing Social Security checks in Dudenoff's name.
Lifeboat[]
The West Tower residents arrange a meeting with the trio and the actors to clear their names in the murder investigation. They tell how they became friends with and received financial help from Dudenoff before he moved to Portugal a few years earlier. Doubting they are telling the truth, Mabel brings in Helga after identifying her on Vince's group photo as another of Dudenoff's friends. Helga tells how suspicious the others have become after the trio's podcast about murders in the Arconia began. They then show a video Dudenoff made that reveals the whole story: Dudenoff found out he was terminally ill, so he committed suicide, but asked his friends to hide his death from Helga and the authorities for the sake of all of their well-beings. Out of sympathy, Mabel decides to not use this information in their podcast, even if it leaves them without a lead. Helga informs them that Sazz contacted her during her investigation and mentioned that her former stunt double protégé turned out to be dangerous. The trio speculates that it was Glen, based on the movie he worked on with Sazz.
Escape From Planet Klongo[]
The trio finds out that Glen replaced Sazz's protégé after the latter was fired from Project Ronkonkoma, the movie they worked on. Learning that Ron Howard directed that movie, the trio tries but fails to track him down on the set of his new film, Escape from Planet Klongo. Meanwhile, Glen is killed after the hospital contacts Sazz's phone about his condition, preventing Mabel from asking him any questions about the protégé. Charles and Oliver eventually meet Ron Howard at a restaurant as he turns out to be Oliver's old acquaintance. He reveals that Sazz's protégé was named Rex Bailey and shows them a photo of him. At the same time, Mabel discovers that the box of beers Sazz brought on the night of her murder contains the original script for the Only Murders in the Building movie with Sazz named as the writer. As Marshall arrives to discuss some changes in the script with Mabel, Charles and Oliver identify him as Rex Bailey and send this information to Mabel, only for Marshall to see the message.
My Best Friend's Wedding[]
Realizing that Rex carried out the murder in 12 minutes by traversing the inner ledge of the building, Charles and Oliver do the same from Vince's window to save a captured Mabel, while Vince and Rudy help them distract Rex. Obtaining his gun, the trio forces him to reveal his motive for killing Sazz. He admits that he envied Sazz's talent after reading her script draft, so he stole and sold it to Paramount under a different name. When Sazz found out, she threatened to expose him, prompting Rex to use his hunter background and Sazz's investigative results to orchestrate her murder. He attempts to kill the trio as well, but they are saved when Jan shoots Rex dead from Charles's apartment, avenging Sazz. The police then arrest her again. A few days later, during Oliver's and Loretta's wedding, a woman named Sofia Caccimelio approaches Charles and Mabel to hire them to investigate her husband's disappearance. They turn her down despite Sofia's claim that her husband has a serious connection to the Arconia. The next day, the trio finds Lester, the doorman, dead in the Arconia's fountain.
Season 5[]
Nail in the Coffin[]
On the day of Lester's funeral, the trio finds a severed finger, confirming their suspicions that Lester's death was not accidental as the police claimed. After Charles checks Lester's body in the coffin and sees that none of his fingers are missing, Oliver learns from his wedding photos that Lester was talking to a man identified as mobster Nicky Caccimelio. They go to Staten Island and meet Nicky's sons and his wife, Sofia, who previously wanted to hire them to investigate Nicky's disappearance. She explains that their family has a dry cleaning business, owning the dry cleaner in the Arconia as well, and tells them about Nicky's gambling addiction. She gives them Nicky's favorite deck of cards as a clue, and Charles discovers that one of the cards is magnetic and contains a hidden map. He and Mabel follow the map, which leads them to a secret casino room underneath the Arconia. At the same time, Oliver finds Nicky's dead body at the Caccimelios's dry cleaner.
After You[]
Before his death, Lester participated in an interview for a study about New York City doormen. He told how he started his job in 1993, mentored by his colleague George. On his first day, he met Charles, Oliver, baby Mabel, and his future wife, Lorraine. Over the years, he assisted the trio through various points in their lives and discovered that George received extra money from Nicky Caccimelio for letting certain people in at his request. After George retired, he introduced Lester to Nicky, who gave Lester the same task. For years, he earned a good income from the commission, although Nicky refused to let him quit when he wanted to. As the number of murders in the building increased recently, Lester hired another doorman, Randall Winston, who started his first shift on Oliver's wedding day. A flash-forward depicts Lester that night fleeing from someone who eventually murders him in the Arconia's fountain with an elevator crank.
Rigor[]
Oliver takes Nicky's body to Charles's apartment after accidentally leaving his DNA on it. Not wanting to involve the police, who might link them to the murder, the trio decides to perform an autopsy themselves. They figure out that Nicky died around the same time as Lester but was frozen, preventing decomposition. They also find a piece of paper in his mouth from Lester's ledger. While Oliver borrows the ledger from Randall, Mabel runs into her former friend, Althea, who is now a famous pop singer and moving into the Arconia penthouse. Charles secretly takes Nicky's body back to the dry cleaner, where it is later found by corrupt police officers who cover up the incident. The trio learns from Lester's ledger the date of an upcoming poker game in the secret casino room, so they decide to attend. There, they see three of New York's richest people arrive, and that one of them, pharmaceutical tycoon heir Jay Pflug, is missing a finger.
Dirty Birds[]
Assuming Jay's involvement in Nicky's and Lester's murder due to his missing finger, the trio decides to trick him into coming over for an interrogation. They record the podcast's season five teaser, hinting that Jay and his billionaire friends might be murderers, which prompts Jay to agree to meet them to clear his name. He arrives along with tech mogul Bash Steed and hotelier Camila White, who all threaten to sue the trio for libel. The trio talks with each of the billionaires privately to make them confess; Charles and Oliver bond with Bash and Camila over their common views on life, while Mabel and Jay discuss their trust issues, with Mabel explaining how her friendship with Althea strained after the latter became famous. The billionaires then reveal that a drugged Nicky chopped off Jay's finger with a cleaver. The trio receives a podcast publishing deal from Wondify. Just as they sign the contract, they realize that Jay's missing finger and the one they found are not the same, but legally they cannot accuse the billionaires of lying due to them being the new majority ownership of Wondify. They are shocked to learn that they have been set up.
Tongue Tied[]
Oliver and Mabel try to obtain information about a person known as "Tommy the Tongue" after learning he used to cover up all illegal activities in the casino room. During their investigation, they discover that the Arconia's new robot doorman named L.E.S.T.R. (Logic Engineered Secure Tenant Robot) disturbs the staff about their jobs becoming redundant, so they hold a building meeting to settle things down. The meeting turns into a riot, ending with the staff destroying L.E.S.T.R. who incidentally contained digital copies of Lester's paperwork. Meanwhile, Charles meets Sofia to find out what she knows about the casino room, but she seduces him and they sleep together. The next morning, he realizes he lost his phone in Sofia's car. Using a tracking app, the trio follows the route of the car, while receiving a call from Detective Williams who reveals that "Tommy the Tongue" is actually a shell company that handles Nicky's gambling money. As Williams tells them that all the money was drawn from the company recently, the trio sees Sofia arriving to a secret meeting with Lorraine.
Flatbush[]
Loretta comes back to New York after her apartment in L.A. burns down, and helps the investigation. She and Oliver go to Flatbush in disguise and follow Sofia and Lorraine to an old theater. Oliver recalls his childhood there and how the theater meant an escape to him from his emotionally unavailable foster parents. They confront Sofia and Lorraine, but they turn out to be innocent, planning to donate Nicky's gambling money to renovate the theater. Meanwhile, Charles, Mabel and Williams discover that the finger is gone, and Althea tells them she heard someone break into Charles's apartment. Upon checking the security footage, they find nothing, causing Mabel to send Althea away, but later regrets it and apologizes. Althea reveals that Mabel abandoned her first after Zoe's death and that her hit song was actually written about her admiration for Mabel. They decide to mend their friendship. Later, Williams discovers that the security footage was edited and that the cameras's distribution company belongs to Bash. He mockingly reveals himself through a dating profile Charles texted with, which he used to gain information about him.
Silver Alert[]
The trio interviews Mayor Tillman for the podcast, and he tells them about Bash's political influence on his mayoral campaign. He gives them his address in the countryside so they can snoop around there. The trio visits Bash's mansion, finding him, Camila and Jay helding a game night. Charles and Mabel challenge them in a game of "Name That Person, Place, Thing" and win due to their category being Broadway and they use their knowledge from Oliver's personal stories. As a winning prize, the billionaires confess to them that on the night of Nicky's and Lester's murder they discussed over a poker game that which one of them will get the rights to build New York City's first casino. Jay also slips that the severed finger has a crucial role in whoever will get the rights, but refuses to explain why. The trio retrives the finger and flee the mansion. Later, Camila visits and forces them at gunpoint to give her the finger. They surrender it as Camila reveals her plan to turn the Arconia into a casino.
Cuckoo Chicks[]
Camila organizes an exclusive game night in the casino room for women only, for which Althea receives an invitation and gives it to Mabel. She wants to use this opportunity to extract a confession from Camila, and invites Williams, Loretta, and Lorraine for help. Posing as a psychic, Loretta makes Camila tell her that she was in love with Nicky, so she proposed a partnership to expand his casino to the entire building. Initially hesitant due to the casino being Sofia's inheritance, Nicky agreed after discovering that his wife was cheating on him. Meanwhile, Charles and Oliver learn that Camila bought up 51% of the apartments in the Arconia, but fail to convince the last seller, Dr. Grover Stanley, to change his mind before the sale is finalized. Loretta finds the elevator crank in Nicky's office with Lester's blood on it, while Lorraine accidentally activates a bird-watching camera that Lester used to record himself before dying. The footage reveals that Randall found and removed the murder weapon from the crime scene.

On their last night in the Arconia, however, Mabel discovers a secret passage in the casino room and that Randall used it to hide inside the building for the last few days. The residents catch and force Randall to confess, but he says he cannot due to his oath to Lester. They then use the new L.E.S.T.R. robot, whose original model is revealed to have recorded Randall and Lester's last conversation: Lester indirectly admitted to killing Nicky to prevent the building from becoming a casino and asked Randall to take the severed finger to Oliver's apartment as a clue for the trio.
