The Mystery Club (1926)

The Mystery Club, an organization of millionaires, draws up an agreement at the instigation of Cranahan, wagering that crimes can be committed without detection by the police; Inspector Burke serves as arbiter. A forfeiture of $25,000 is set, and the members draw secret lots to decide who is to be the criminal. When Burke himself is reported murdered, the members agree to cancel the agreement but cannot find the document.
