Sing Sing nights

Three men on death row at Sing Sing each insist they committed the same murder, yet only one can be guilty. The warden promises a pardon to whichever of them spins the most compelling yarn. What follows is three tales, which make up most of the book. The first is a detective story chasing the legendary "12 coins of Confucius." The second unfolds at a masquerade ball, where a guest wears a moth costume. The third imagines a human brain placed inside the body of a gorilla.
