John Dickson Carr a Critical Study

John Dickson Carr is known as the master of the -locked-room- mystery--the -impossible crime.- But Carr also wrote short stories, radio plays, essays, introductions, and book reviews. S. T. Joshi has written the first full-length study of Carr's entire work and pays particular attention to this author's three best-known detectives: Henri Bencolin, Dr. Gideon Fell, and Sir Henry Merrivale.
