The Witch of the Low Tide

Lady Betty Calder is a prostitute and a blackmailer - or is it her sister, Glynis, using her name? Dr David Garth, her fiancé, knows he must find out the truth - especially when he blunders across Glynis' strangled body on Betty's property.

The police know she did it, but David knows she didn't, and he must outwit a cunning murderer and a hostile detective-inspector to prove it. What he discovers - about his best friend's wife, his medical assistant, and even his fiancée - make him wish the blackmailing Glynis had never lived.
