The wealthy Mr Shaitana has a strange hobby: he collects murderers. Terrible crimes, the killer's tactics, the logic of the atrocity - his secret passion. And yet - risk. One day Shaitana invites eight guests to dinner: four detectives, including the famous Hercule Poirot, and four alleged murderers. The conversation about unsolved murders smoothly turns into a game of bridge. The host leaves the players and settles down in an armchair by the fireplace. But when the game ends, the guests find the man dead. Someone has stabbed Mr Shaitani right through the heart with a stiletto. And this someone is a skilled player who has been bluffing perfectly all this time.
