What a fun little book! Definitely not for kids, although a particularly bright 12-year old might enjoy it. Some of the solutions are relatively easy, but others require pretty specific knowledge of a subject to figure out the answer. All of the solutions are in the back of the book, and they all make sense. A neat way to pass a few minutes.
This is a very unique book: you read a 3 to 6 page story and then YOU have to solve the mystery. All the clues are contained in each story. And if you just can't figure it out, the answers are in the back of the book. 37 challenging cases in all, and a ton of fun!
