Ulf and the Kidnapped Teacher

Kidnapped?! Ulf, Tita, and the rest of the detective gang can’t believe their eyes. Ms. Süllmann has been kidnapped?! Their homeroom teacher? What?! But the ransom note is unambiguous: “495 euros ransom. No police! No adults!” And Ms. Süllmann is indeed nowhere to be found... Nothing’s happened for years, and now this! But when they’re needed, the detectives are on the case. While the rest of the class tries to scrape together the ransom money, Tita, Otto, Heiko, Uli, and Ulf set out to find their teacher... A case that quickly gets crazier and crazier. And not just because of their investigative blunders.
