Lionel Twain (Truman Capote) has invited the five greatest detectives to a "dinner and murder." How can they resist? Included are a blind butler, a deaf-mute maid, screams, spinning rooms, secret passages, false identities, and more plot turns and twists than are decently allowed.

This movie marked the film debut of James Cromwell.

Continuity: Milo Perrier tells Sam Diamond "I'm not a Frenchy... I'm a Belgie" referring to the fact he is from Belgium and not France. However, in discussing Twain's annual poodle hunt in France, he implies that's his home country, and he says, referring to himself, that you should "never underestimate a Frenchman's nostrils."
