Inspector Thiel is faced with a challenge: instead of solving a murder, this time he has to prevent one. Meanwhile, Professor Boerne tries to be a patron, Silke Haller goes looking for clues with Mirko Schrader. The reason for all this is Stan Gold, a long-lost son of the city who has returned to his homeland from the Paraguayan jungle. Gold is not only now a star author, but also Münster's new city clerk - and a former classmate of Thiel's. Only back then his name was not Stan Gold, but simply Hotte Koslowski and he was otherwise rather mediocre. It is only thanks to the courageous intervention of Professor Boerne that he can enjoy his late triumph for more than a few hours. As soon as the new city clerk is elected, he almost dies of anaphylactic shock. And that's just the beginning of a whole series of dramatic events in which Stan Gold becomes involved.
