Publisher's Synopsis
Doctor Morelle is a Harley Street Psychiatrist. His assistant, the timorous Miss Frayle, is walking to a party when she encounters a wounded man who collapses in front of her. She runs to get assistance, only to find he has disappeared - leaving nothing but a pool of blood on the road. Investigating, Doctor Morelle and Miss Frayle come up against a glamorous woman thief, a plot to rob a baron of millions of pounds - and a murderer.
