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. Andrew then appears to fatally shoot Milo.
