John Rhode 
Muder at the Motor Show [EPUB ebook] 

Murder at the Motor Show first published in 1935 (published in the U.K. as Mystery at Olympia), is book no. 21 in the Dr. Priestley detective story series. Author John Rhode, a pen name of Cecil Street (1884-1964), was a prolific writer of mostly detective novels, publishing more than 140 books between 1924 and 1961. From the dustjacket: A dense crowd surrounded the new Comet car that was fully expected to be the sensation of the great Motor Show at Olympia. Suddenly one of the eager spectators, an elderly man, lurched forward and collapsed in what appeared to be a dead faint on the ground. But Nigel Pershore was dead, and it was his death that provided the real sensation of the show. A post-mortem examination revealed no visible wound, no serious organic disorder, no evidence of poison. Doctors and detectives were equally baffled. Every chapter unfolds a new aspect of an apparently insoluble puzzle. Then a fortunate discovery opens the way for Dr. Priestley’s unrivaled deductions and a solution of the mystery that brings to a close a brilliant story.
