The cases of Chase and Delacroix

Description

"In the Great Depression, millionaire polymath Abel Chase and his associate, Claire Delacroix, are requested to investigate the San Francisco Police Department's most baffling cases: an actor found dead in his locked dressing room, with two tiny punctures in his neck; a deep-water explorer who disappears from his diving suit, sixty feet beneath the surface of Monterey Bay; and a test pilot who, on a flight with her passenger in an experimental plane, emerges from cloud cover - alone!"--Publisher description.
