Mystery jigsaw puzzles were popular back in the 1930's until the puzzle craze abated. Janus Games brought out a line called Janus Mystery Jigsaw Puzzles in the 1970's. The author of the mystery to be solved here is Henry Slesar. Copyright date is 1973.. Please don't show the box cover to whomever attempts to solve the case. They should read the case printed on the box, try to solve it first, then assemble the puzzle which shows the solution. Puzzle has 15 figure pieces (6 guns, 6 daggers, 3 battle axes), presumably selected as instruments of "mayhem and murder"! A fun evening for your family and friends.
