In each round, four suspect cards are placed face up on the table. Players attempt to 'prove' which suspect is the real criminal by playing evidence cards - cards that match the clothing worn by the suspect. A suspect is confirmed as a criminal when five different evidence cards matching the suspect are played, or when the other three suspects have been eliminated by having alibi cards played on them. Players receive a bonus for playing evidence matching the one true criminal and receive bonuses for being the one to capture a criminal. The game ends when all suspects have been captured, and the winner is the player who has accumulated the most points. - BoardGameGeek
