Piece together the world of Sherlock Holmes in this detailed jigsaw puzzle depicting the London of his day. As you build the puzzle you can spot a variety of locations (such as 221B Baker Street), fictional characters (from the hound at Baskerville Hall to Moriarty, Holmes, and Dr. Watson), crime-solving clues, and—last but not least—real historical figures such as Arthur Conan Doyle himself, Queen Victoria, and J.M. Barrie, among others.
