The “brilliant” and baffling puzzle book that launched the “solve-it-yourself” mystery craze of the 1920s and ’30s (New York Times).

Calling all mystery puzzle fans! This is the book that launched the “solve-it-yourself” detective book craze of the 1920s and ’30s, spawning numerous imitators and a four book series of its own. These short crime problems incorporate all of the clues needed to find their solutions, including maps, charts, cryptograms, and additional illustrations—but it’s up to the reader to put all of this together and find out whodunit. (Correct answers included at the end of the book.)

Challenging and entertaining, The Baffle Book promises hours of armchair sleuthing delights, either on your own or at a “Baffle Party” as the book’s opening recommends. The authors award credits for each of the questions posed, depending on their difficulty, with a chart onto which scores can be added and a grade given for how well the amateur sleuth performed.
