Plot summary
David Garth, M.D., has fallen in love with the beautiful widow Betty, Lady Calder. Detective-Inspector Twigg of Scotland Yard tries to warn Dr. Garth about the chequered past of Lady Calder, but it takes all the nerve of Garth's friend Cullingford Abbot, assistant to the Commissioner of Scotland Yard, to state that, among other things, Betty danced for three seasons at the Moulin Rouge and is thought to have joined a Satanist group in Paris. She is also reputed to be a blackmailer responsible for at least two suicides. However, Betty herself raises the possibility that she is being mistaken for the machinations of her sister Glynis. When Glynis is found dead on the beach near a bathing-pavilion, in the middle of a stretch of unmarked sand, Betty is suspected of arranging the death (although no one can suggest how it might have happened). It takes Dr. Garth's special knowledge of both medicine (the new science of "psychoanalysis" which suggests that abuse of a child may be the fault of the child) and literature like Gaston Leroux's The Mystery of the Yellow Room to solve the impossible crime and reveal the criminal.
