We finally got the mystery puzzles out yesterday and are really happy with them. So far we have completed Kit's and Molly's. They have just the right amount of difficulty for a child in the target range and the answers are interesting. There is a booklet included with the puzzles and it has four short mystery stories, one for each girl. As an adult I found the answers to be easy to figure out without putting the puzzle together, but again, for a child in the target age they are the right level of difficulty. Kit's puzzle was a little time consuming, but the answer to her mystery was apparent after assembling only part of the puzzle. The answers to the mystery can be found after putting the puzzle together and then turning off the lights. The answer glows in the dark. Overall A+
