Case for Three Detectives is possibly the most unusual mystery ever written. A murder is committed, behind closed doors, in bizarre circumstances. Three amateur detectives take the case: Lord Simon Plimsoll, Monsieur Amer Picon, and Monsignor Smith (in whom discerning readers will note remarkable likenesses to some familiar literary figures). Each arrives at his own brilliant solution, startling in its originality, ironclad in its logic. Meanwhile, Sergeant Beef sits contemptuously in the background. "But," he says, know who done it."
