From the English Edition:
Inspector Cito (diminutive of Inspector because he is very small), the detective who is famous throughout the world for his wit and his love for Spanish omelette, works for the Department of Strange, Mysterious and Super Difficult Cases with the help of Chinese sergeant Wee Chou Fear (playing with the name to sound like “Without fear”).

Inspector Cito starts the day in a bad mood. His boss, Captain Storm, not only has interrupted his breakfast, but has ordered him to teach a trainee from China, Wee Chou Fear. He has arrived in order to learn our Inspector Cito’s techniques of investigation. Cito is angry because it is his breakfast time, and he will have to share his Jabugo’s sandwich, which Wee Chou Fear eats with chopsticks.

The book includes a detective game on the back: boys and girls must find 9 little paper boats hidden all around the book illustrations!
