The Black Dream — Constance Little; Gwenyth Little

Agatha Bunson desperately wanted to fire the cook at her boarding house but her father's will made that impossible. Then someone very kindly murdered the cook. Agatha, who was given to sleepwalking, thought she might have done the deed and hid the body. Among the potential murderers are two bickering doctors (once engaged to each other), a female secretary who thinks she's a real glamour girl, an interior decorator with a taste for martinis, and several members of the dead woman's family. First published in 1952. this is the 18th of 21 Little books to be rereleased by The Rue Morgue Press.
