Description

---

Join the master sleuth as he and Dr. Watson examine interrupted chess matches at clubs and country homes, examining the pieces' current positions to identify previous moves. Rather than predicting the outcome of these games, the Baker Street duo focus on past events, using the same variety of logical reasoning that unlocks the secrets to their ever-popular mysteries. Holmes instructs Watson (and us) in the intricacies of retrograde analysis in order to deduce on which square the white queen was captured, whether a pawn has been promoted, and which piece has been replaced by a coin. The mysteries grow increasingly complex, culminating in a double murder perpetrated by the devious Professor Moriarty.
Philosopher and logician Raymond Smullyan brilliantly recaptures the mood of Sir Arthur Conan Doyle's tales. Readers need only a knowledge of how the pieces move; the first puzzles explain all of the concepts that arise later on. These witty and challenging problems will captivate chess aficionados, puzzle enthusiasts, Sherlock Holmes fans, and everyone who relishes mysteries, crime stories, and tales of detection.

Raymond Smullyan received his PhD from Princeton University and taught at Dartmouth, Princeton, Indiana University, and New York's Lehman College. Best known for his mathematical and creative logic puzzles and games, he was also a concert pianist and a magician. He wrote over a dozen books of logic puzzles and texts on mathematical logic. Raymond Smullyan: The Merry Prankster Raymond Smullyan (1919-2017), mathematician, logician, magician, creator of extraordinary puzzles, philosopher, pianist, and man of many parts. The first Dover book by Raymond Smullyan was First-Order Logic (1995). Recent years have brought a number of his magical books of logic and math puzzles: The Lady or the Tiger (2009); Satan, Cantor and Infinity (2009); an original, never-before-published collection, King Arthur in Search of His Dog and Other Curious Puzzles (2010); and Set Theory and the Continuum Problem (with Melvin Fitting, also reprinted by Dover in 2010). More will be coming in subsequent years. In the Author's Own Words: "Recently, someone asked me if I believed in astrology. He seemed somewhat puzzled when I explained that the reason I don't is that I'm a Gemini." "Some people are always critical of vague statements. I tend rather to be critical of precise statements: they are the only ones which can correctly be labeled 'wrong.'" -- Raymond Smullyan
