Although Daisy Pepper and Ridley Long are very good private detectives, they would welcome some help. You can assist them in solving forty different mysteries, but don't think it is going to be easy. You will have to watch very carefully for visual clues. You will be required to figure out some secret codes, put random pieces of a puzzle together, and arrange events in a time sequence. The most important skill you'll need to help solve these mysteries is logical thinking. So rev up your brain and get going -- and good luck! Book jacket.
