When a celebrated boxer is killed in the ring, Inspector Ripple initially thinks the affair is a tragic accident. Amos Petrie, an eccentric solicitor from the Public Prosecution Department, thinks otherwise. When evidence emerges that the cause of death was poison, Ripple is forced to concede that Petrie is right. But how on earth was the poison administered? And who could have desired the man's death?

Originally published in 1932, this vintage murder mystery introduces Amos Petrie - solicitor, fisherman and talented sleuth.
