Search - DANCERS IN MOURNING

Another great Allingham book. It's amazing how she keeps you guessing "who done it." I couldn't put it down.
"Nasty pranks were being played on dancer Jimmy Sutane, star of London's Argosy Theatre. They began backstage as tuppenny-ha'penny squirts of malice. They became a pound's worth of trouble when they spread to the Sutanes' country estate. Someone wanted Jimmy's famous feet to tap their final performance."

CONFIDENTIAL INVESTIGATOR - ALBERT CAMPTON
A tall, thin man with overly large spectacles, he is deceptively unobtrusive when tracking down a killer and uncannily capable of predicting the deadly twists of a criminal's mind. He is unquestionably a gentleman, but even Lugg, his dauntless valet, and his friends at Scotland Yard don't know all the secrets in Campion's past-- or the confidential cases he has covertly solved while in His Majesty's Service.
