Immerse yourself in Sherlock Holmes's London with this big 1,000 piece puzzle. Ah, but once the jigsaw is done, the game is afoot, as you search for 50 places and people from Sherlock's cases—including Dr. Watson, Moriarty, Mycroft, the hound at Baskerville Hall, and of course 221B Baker Street—as well as real historical figures of the era. A fold-out poster of the full image provides clues and fascinating facts about Arthur Conan Doyle and his creation, and the finished jigsaw measures 27 x 19 inches.
