Framework part 1
Shortly after renting an old country house, film star Paul Henderson mysteriously disappears and Inspector Holloway from Scotland Yard is called to investigate. Inquiring at the local police station, Holloway is told some of the house's history.
Method for Murder (Fury No. 7, July 1962)
Charles Hillyer, a hack writer who specialises in horror stories, and his wife Alice, move into the house. Charles begins working on a novel focusing on Dominic, a murderous, psychopathic strangler; Charles becomes simultaneously enamoured and disturbed by the character. Charles soon starts to see Dominic, who begins stalking and tormenting him.
Charles begins seeing a psychologist, Dr. Andrews, who suggests Dominic is the other half of a split personality formed by Charles getting into Dominic's mindset to write the novel. Charles's visions of Dominic become even more pronounced. He sees Dominic strangling Alice, only for her to claim that Charles had been strangling her. At another session with Dr. Andrews, Andrews suggests Dominic is the result of darker sides of Charles's personality being released by writing the novel, though Charles is sceptical as he has written horror stories for years and never had a problem. Suddenly, Dominic arrives and strangles Dr. Andrews while Charles lies back in a chair with his eyes closed. When the doctor stops responding, Charles opens his eyes, and, jumping to his feet, backs away, screaming in horror as Dominic laughs.
At the house Dominic approaches Alice, only to reveal that he is actually Richard, her lover. Richard, an actor, had been pretending to be Dominic to drive Charles insane, so that Alice and Richard could take the money made from his novels and run off together. Alice gets a call from the police, and learns that both Dr. Andrews and Charles had been strangled to death. Alice asks Richard why he had killed them, as it was not part of the plan, only for Richard to reveal he now believes he is Dominic. Richard/Dominic then strangles Alice while laughing maniacally.
Framework part 2
Sergeant Martin informs Holloway that Richard/Dominic was later found standing over Alice's body, laughing. He says he believes that it was not merely a case of Richard/Dominic being driven to madness by the role, but some effect of the house itself. Holloway dismisses this as absurd, so Martin tells him another story, of the next tenant to inhabit the house.
Waxworks (Weird Tales Vol. 33 No. 1, January 1939)
Retired stockbroker Philip Grayson moves into the house. Though initially he occupies himself with his hobbies, he quickly becomes lonely. One day, while wandering around town, he happens upon a wax museum. Grayson explores the museum and finds a sculpture of Salome which resembles a dead woman he had been in love with. The museum's proprietor explains that he based the likeness of the sculpture after his late wife, who had been executed after murdering his best friend. Disturbed, Grayson vows never to return.
His friend Neville Rogers arrives at his home while travelling on business. Grayson eagerly invites him to stay the night, and it becomes clear the two had both been romantic rivals for the same woman; however, the two had reconciled after her death. The next day, Grayson takes Neville around town, and the two spot the wax museum. Though Grayson tries to persuade him not to, Neville enters the wax museum and spots the sculpture, becoming obsessed with it. Neville tries to leave town, but is unable to abandon the sculpture. Staying at a local motel, he calls Grayson and informs him of his predicament. When Grayson arrives, he finds Neville has left for the wax museum. Grayson goes to the museum, and finds Neville's severed head has been added to an exhibit. The proprietor arrives and reveals he had framed his wife for his friend's murder, so that he could cover her corpse in wax and keep her to himself forever. However, men continue to become enamoured with her, and some, like Neville, become obsessed, which puts him into a murderous rage. The proprietor then murders Grayson with an axe, and adds his head to the Salome exhibition.
Framework part 3
Holloway asks if Henderson moved in next, and is told that there was one other tenant before him. However, Holloway does not stay around to hear this story, believing the whole thing preposterous, and instead decides to confer with the estate agent, A.J. Stoker. Stoker tells Holloway that he "tried to warn them" of the house's "secret", and asks Holloway if he has "guessed it yet". Holloway ignores this, dismissing this too as absurd, and instead asks him what happened to the tenant before Henderson. Stoker explains.
Sweets to the Sweet (Weird Tales Vol. 39 No. 10, March 1947)
Widower John Reid moves into the house along with his pyrophobic young daughter Jane. John hires former teacher Ann Norton to tutor Jane. Ann gradually bonds with Jane, and she helps Jane get over her fear of fire and teaches her how to read, but begins to suspect John is abusive: he does not allow her to play with other children or own toys, and does his best to keep her isolated.
Norton confronts John about his parenting, and asks if he blames Jane for the death of his wife, to which John responds that he is glad his wife is dead. Norton manages to get John to allow her to buy Jane some toys; when John discovers a doll amongst the toys bought, he snatches it from Jane and tosses it in the fire. Jane begins to secretly read books about witchcraft. One night, during a blackout, John discovers some of the candles are missing. John angrily questions Jane about this and slaps her, to Ann's horror. Jane secretly uses the missing candles to form a wax voodoo doll, which she uses to leave John bedridden.
He reveals to Ann that Jane's mother was a witch, and that Jane is as well; the reason for his parenting methods were to stop Jane from harming anybody. When Jane begins to attack John via the doll once again, he instructs Ann to find the doll and take it from Jane to stop her from killing him. Ann finds Jane standing next to the burning fireplace holding the doll; Ann tries to convince her to give her the doll, but Jane tosses the doll into the fire. Ann listens in horror as John burns to death and Jane smiles evilly.
Framework part 4
Holloway dismisses this story as the most ridiculous so far, and demands the estate agent tells him about Henderson. Stoker clarifies that he warned Henderson not take it, not believing it would be "right for his personality", but states that he gave in once Henderson insisted. He then tells his final story.
The Cloak (Unknown May 1939)
Temperamental veteran horror film actor Paul Henderson moves into the house while starring in a vampire film being shot nearby. Henderson, a great fan of the horror genre, is angry over the lack of realism in the film, particularly over the cloak worn by his character (who happens to be a vampire). He decides to purchase a more accurate cloak, and to that end stops at an antique shop run by the enigmatic Theo von Hartmann. Von Hartmann offers him a black cloak after listening to Henderson's demands, and Henderson purchases it. Before he leaves, von Hartmann tells him to use the cloak for its intended purpose.
While in his makeup room, Henderson finds that when he wears the cloak, he has no reflection. Later that day, while shooting a scene where he sucks the blood from his costar and girlfriend Carla, Paul begins genuinely trying to suck her blood even after the scene ends. A horrified Carla demands he stay away from her. At midnight, the witching hour, Paul puts on the cloak again as a test. He grows fangs and begins to fly, much to his horror.
Paul reads in the newspaper that von Hartmann's shop has burned down and von Hartmann's corpse has been found inside; the corpse was identified as being several hundred years old. Paul realises that von Hartmann was a vampire, and that he gave Henderson the cloak so that he could pass his powers on to Henderson, allowing him to die. Henderson apologizes to Carla and invites her over to his home; he explains to her his predicament, but she is skeptical and demands he prove it by putting on the cloak. Henderson is reluctant, as it is midnight, but he ultimately complies. Paul is relieved to find that nothing happens, but he quickly realises that the cloak had been substituted with a prop. Carla dons the cloak and reveals she is actually a vampire sent to turn Henderson into another vampire, as most vampires admire his portrayal of their kind. Carla flies towards a screaming Henderson and begins to turn him into a vampire.
Framework part 5
Holloway refuses to believe Stoker and goes to the house, despite it being nearly midnight and the house having no electricity. He explores the house by candlelight, eventually breaking into a locked basement where he finds and kills Henderson, now a fully transformed vampire. He is himself then killed by Carla.
The next morning, Stoker walks up to the house and breaks the fourth wall by talking to the audience – asking if they understand the secret of the house: that it reflects the personality of whoever is living in it and treats them accordingly. He muses that perhaps the audience would be suitable, and "that there is nothing to be afraid of, provided [they're] the right sort of person".
