Taken from such works a A Study in Scarlet, The Sign of the Four, The Hound of the Baskervilles, and The Case Book of Sherlock Holmes, 72 puzzles challenged the reader's abilities in language, math, codes, and, of course, deductive reasoning. Dr. Watson retells each story and, at the end, Holmes poses a new conundrum relating to the adventure.
