They couldn't find him. They traced him as far as Pennsylvania Station where he seemed to vanish into thin air. His name was Panty Burke, a "percentage operator." Lt. Marsh of Homicide said that he'd been forging pari-mutuel tickets and had taken a powder. Grace Larkin, Panty's gorgeous and loyal fiancée, said that wasn't true-that Burke was a good guy and something awful must have happened. And Doc Connor, who had a weakness for a lovely lady, believed her-and found himself trying to outwit both Eddie Marsh and a ruthless killer. Murder is Mutuel was first published in 1948.
