My wife Linda is a big mystery fan. She gets "hooked" by the puzzle to be solved in the story and by the way the characters come up with the solution. She finds it a challenge to try and solve the mystery before it is revealed in the book. Once you start reading a good mystery you will find it very hard to put it down until you are finished!
