Elizabeth Daly fashioned herself as a U.S. version of Agatha Christie, writing the same kind of mysteries but setting them in New York City. We gather that she was even Christie's favorite mystery author, which is quite an accolade. Murder Listens In is seventh in Daly's Henry Gamadge series—the main character being a sleuth who writes mystery novels—and he's drawn into this puzzle by a crumpled note with his name and address on it found by a postman outside an Upper East Side mansion, and is soon dealing with a client who insists on anonymity to the point of throwing him notes out a window. Someone in this house filled with distant relatives and servants is in deep trouble, and Gamadge, with the help of his wife Clara and his sidekick Schenck, has to figure it out before someone (else) dies. Exceedingly well reviewed, and deservedly so. Originally published in 1944 as Arrow Pointing Nowhere, with this Bantam paperback appearing in 1949 graced by Harry Schaare cover art.
