Dr. Priestley Lays a Trap, first published in 1933 (and also known by the title The Motor Rally Mystery),
 is part of the series of mysteries featuring private detective Dr. 
Priestley. 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: The 
death of Lessingham and his companion, Purvis, was, indeed, a tragic 
affair; but an automobile accident, especially one occurring in a race, 
rarely arouses suspicion. Sergeant Showerby, however, was a 
conscientious soul. His duty was to investigate thoroughly and 
investigate he did, with results that were suspicious enough to arouse 
Inspector Hanslet of Scotland Yard and, through him, the great 
criminologist, Dr. Priestley. At first, there is so little 
evidence that one cannot understand Dr. Priestley's interest in the 
case. Then, one by one, clues appear - not the ordinary clues which fall
 fortuitously in a detective's lap, but clues that are found because the
 Doctor, by his famous process of logical deduction, knows where to look
 for them. Gradually a pattern forms so diabolical in its simplicity and
 effectiveness that Dr. Priestley is forced to set a dramatic trap which
 very nearly ends the lives of both detective and criminal. For 
sheer ingenuity of detective story mechanics, John Rhode has few equals 
and none of his many stories present a neater puzzle than this one, 
which will perplex all but the keenest detective fan.
