The Secret of the Jagged Jigsaw? The Case of the Missing Corner Piece? When the Hardy Boys weren't busy unmasking kidnappers and smugglers, we suspect brothers Frank and Joe Hardy enjoyed solving the occasional jigsaw puzzle! Amateur sleuths (or, at least, lifelong mystery fans) will appreciate this collage of more than fifty classic Hardy Boys book covers, their colorful, action-packed images transformed into a challenging 1,000-piece puzzle. Measures about 26½"x19¼" when assembled. And for fans of Nancy Drew, we're also offering the Nancy Drew Puzzle.
