This is a weak mystery novel. There are only a few crossword puzzle clues that are a part of the story and they are not very difficult. If you are a huge crossword puzzle fan I would not recommend getting this book on that basis. As far as the other parts of the mystery there are very few clues. I found the reveling of the mystery to be extremely unsatisfying. The characters themselves and the dialogue of the novel are also sub-par. The Puzzle Lady has some life but little depth and the other characters are almost completely flat. There are definitely better mysteries out there.
