MEET SHERLOCK HOLMES' ONLY SERIOUS RIVAL AT DETECTION!

Meet Professor Augustus S. F. X. Van Dusen, who The Encyclopedia of Mystery and Detection calls "the most cerebral of all detectives." One of the great scientific detectives, a master logician, the Thinking Machine solves cases brought to him by a reporter, Hutchinson Hatch, who also does the legwork on most of the adventures.

Professor Van Dusen has an abnormally high and broad brow, topped by a shock of yellow hair. The Thinking Machine made his debut appearance in 1906, and is considered Sherlock Holmes only true rival. This ebook edition contains two Thinking Machine books. The Problem of Cell 13 and Other Thinking Machine Stories, which Ellery Queen named one of the 100 "Cornerstone" books in the history of the mystery novel, and The Encyclopedia of Mystery and Detection hailed as "the best narratives about the eccentric genius." Also included in this omnibus volume is the only other book about Professor Van Dusen during the author's lifetime, The Thinking Machine on the Case. Here are twenty-two narratives that will delight any fan of gaslight mysteries and the era of the handsom cab.
