By day, the 20-year-old wanna-be sleuth Jrme translates detective novels, while by night he’s enrolled in Professor Maison’s correspondence course for private eyes. And when fifteen people in Paris have been killed by poisoned darts, Jrme gets his first case, capturing a flamboyant assassin who uses a blowgun. Unfortunately, things get off to a rocky start when the professor appears to be victim number sixteen! Translated in English for the first time.
