Plot
Andrew Wyke, a successful crime fiction author, lives in a large country manor house filled with elaborate games and automata. He invites his wife's lover, Milo Tindle, a London businessman, to his home to discuss the situation and would like Milo to take his wife off of his hands. To provide him the means to support her, Andrew suggests that Milo steal some jewelry from the house, with Andrew recouping his losses through an insurance claim. Milo agrees and Andrew leads him through an elaborate scheme to fake a robbery. At the conclusion, Andrew pulls a gun on Milo and reveals the bogus theft was merely a ruse to frame Milo as a burglar so he can kill him. He puts the gun to Milo's head; there is a gunshot, and the screen cuts to black.
A few days later, Inspector Doppler arrives to investigate Milo's disappearance. Andrew purports to know nothing, but as the inspector collates incriminating clues, Andrew breaks down and explains the burglary hoax. He insists he only pretended to shoot Milo using a blank cartridge and that his rival left humiliated but alive and unharmed. After finding evidence supporting a murder, Doppler arrests Andrew. As Andrew is about to be taken to the station, Doppler reveals himself as the heavily disguised Milo, seeking revenge on Andrew.
The score is seemingly evened until Milo announces they will play another game involving a real murder. Milo says he fatally strangled Andrew's mistress, Téa, and has planted incriminating evidence throughout Andrew's house. The police will arrive soon. Andrew dismisses his claim, but phones Téa to be sure, only to learn from Téa's flatmate, Joyce, that Téa is dead. Following Milo's cryptic clues, Andrew frantically searches the house for the planted evidence. Andrew finds the last item just as Milo says the police are arriving. The disheveled Andrew pleads with Milo to stall them while he composes himself. Milo is heard talking to the officers, but there are actually no police. Milo then reveals that he faked Téa's death with Joyce and Téa's willing assistance, thus tricking Andrew a second time.
