Death Takes a Bow when Mr. North, a book publisher, is asked to introduce one of his authors, Victor Sproul, at a lecture in a fashionable New York discussion club. The introduction completed, Mr. North turns to find the speaker unable to rise from his chair on the platform. Minutes later, Sproul is dead - apparently poisoned. Mrs. North, of course, is in the audience, and so is the wife of Lieutenant Weigand of the New York Homicide Squad. Arriving on the scene, Weigand finds a particularly clueless case, with little or nothing to go on except the mysterious activities of an uncatchable little man with a dark complexion who steals Sproul's lecture notes — and then returns them to the police!
