The Case of the Treehouse Spirit & Other Solve-It-Yourself Whodunits

There aren't too many kids who do their homework in an empty interrogation room while their parents solve crimes. But then again, Emma Riley is not your average thirteen-year-old. For one thing, she loves puzzles, and also, she spends a lot of time at police headquarters, which has made her really good at solving cases! In fact, whenever there's something amiss in Beaverton, Indiana, you can be sure Emma is ready to solve the case.

In the seventeen stories in this book, you have the chance to solve the case before Emma does! All you need to do is read a story, reason it out, and check the solution at the back of the book.

Happy sleuthing!
