Inspector Spithamis, a world-famous detective known for his skills and love for omelets, works in the Department of Strange, Mysterious, and Super Difficult Cases.

The day started badly for Inspector Spithamis. Not only did his omelet burn, but he also has to rush out of town to solve a big mystery: burglars broke into a factory that makes umbrellas. But - how strange! - they didn't steal anything. They only destroyed the machines. There are quite a few suspects, and the case is getting more and more complicated...

By reading the book, you too can become a detective and search, besides the solution to the mystery, for the paper boats hidden in the illustrations.
