Murder à la Richelieu

Adelaide Adams is a tough old spinster, living a quiet life at the Hotel Richelieu, somewhere in the southern United States. But her peaceful existence is shattered when a man is found brutally murdered in her room. More murders follow and, as suspicion falls on all of the hotel residents in turn, Adelaide teams up with the handsome salesman Stephen Lansing to solve the crime. But with a psychotic killer on the loose, they find that amateur sleuthing is not the safest of pass-times... 

Originally published in 1937, this is a classic mystery from the golden age of American crime fiction. 

A second Adelaide Adams mystery, "There Is No Return" (1938), is also available from Black Heath Editions.
