Death on the Boat Train, first published in 1940, is book no. 32 in the series of mysteries featuring private detective Dr. Priestley and Scotland Yard’s Superintendent Hanslet and Inspector Jimmy Waghorn. 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: Fair blew the wind from France, and the Channel steamer Isle of Jethou rolled a bit in the stiff southwesterly breeze. But the rough crossing didn’t upset the mysterious passenger who had locked himself into his cabin as soon as he boarded the boat at Guernsey. The same desire for seclusion had manifested itself on the boat-train to Waterloo, for the guard had been presented with a pound-note to reserve a compartment for Mr. Mystery. But did he travel alone? For at Waterloo the gentleman from Guernsey was a pretty genuine corpse. Death on the Boat-Train is a first-rate detective story, once again featuring the coldly clever scientific mind of Dr. Priestley, John Rhode’s brilliant creation.
