The game consists of 15 different murder cases which have to be solved by the players. Each case has 27 clue cards which can be acquired and either hidden or published by the player who holds them. The clues have different values, but only the player who holds a card knows that value. Each player's card rack can only hold three cards, but cards can also be swapped or stolen. At the end of each turn, a player can make a guess who the murderer is. When one player's pawn reaches a certain position on the game board, the case history is revealed and the players receive points for their guesses and their clue cards. Each of the 15 cases can only be played once by a given group. (User summary by HilkMAN)
