The next morning young Paul De Forrest lies stabbed to death in his apartment at the fashionable Avon – and under his hand is a slip of paper bearing the name of his murderer. But Franklin Chase has an alibi that is accurate to the minute: three clocks, three witnesses, two and a half miles away. The reporter Hutchinson Hatch takes the case to Professor Augustus S. F. X.
