Each chapter or story involves a separate mystery that is solved through the interaction between the characters of the elderly Mr. Satterthwaite and the eponymous Mr. Quin who appears almost magically at the most opportune moments and disappears just as mysteriously. Mr. Satterthwaite is a small, observant man who is able to wrap up each mystery through the careful prodding and apposite questions of Mr. Quin.
