First published 1941; cover shown is the 1955 Penguin Books (UK) paperback edition. 203 pages.
Set in Montego Bay, Jamaica during WWII, this mystery had little to interest me. It seemed sadly dated, and I am sick to death of reading about helpless females.
I'll leave it to the Penguin synopsis to outline the basic plot:
"... the author makes full use of the local background, with its black nights and the fog coming in from the bay. Against this scene unfolds the story of Elizabeth Dakin, who is married to a millionaire dipsomaniac, and who is preparing her escape when he is shot. Suspicion immediately falls on her, but there are others in the tangled affairs of the Dakin household. More than a mystery story, this is a novel of emotional intensity."
