Book Description
John Mannering (aka ‘The Baron’) is an ex-cracksman, who is now ‘straight’, and also acts to solve crimes. His wife learns that Quinns, a curio shop in London’s Mayfair is for sale, and urges him to buy it. His attempt to do so, however, is shrouded in mystery, and the police wonder if he has once again turned his hand to his old profession.
