From the Alphabet Murder Puzzle Series, this jigsaw combines grueling puzzling with a murder mystery. First you must assemble two different 500 piece puzzles of "before" and "after" crime scenes. To preserve the mystery, no actual puzzle art is shown on or in the box. But that's not all-the puzzle pieces for both puzzles are in the same bag! After you complete the puzzles, you read a mystery booklet and, using the evidence provided in the jigsaw puzzles, you solve the baffling murder mystery. Two 13" x 19" puzzles.
