This was my first mystery puzzle and I am hooked. It was really fun to discover the mystery and reveal it as the puzzle was filling in. Solving it with the story sheet was surprisingly fulfilling -- an extra puzzle fun. The image is beautiful. The pieces are good quality and well cut, but there was quite a bit of puzzle dust if you are sensitive to that. The color is well saturated and pieces generally fit well, a few issues, but the image was clear to fix that. It was about 12 hours to finish from sort to solving - but I was motivated to get to the sleuthing. I would say this is a medium difficulty, but experienced puzzlers easy. Great for a family with different ages .... I recommend this puzzle highly.
