In the heart of Brandenburg, on the banks of the Havel, the body of a clergyman is discovered. It's not an easy case for Manzetti, a criminal investigator of half-Italian descent but without a Catholic upbringing. During his inquiries, he quickly finds himself facing a watcher sent by the Curia. With a southern European ease, he struggles to make progress in this case. Only his sharp mind and good education assist him when the murderer presents him with a second body at Beetzsee: the murder of the teacher is staged in the same way as that of the deacon. And then, the charming and likable Manzetti loses his cool Italian temperament and clashes with a slick lawyer who obstructs his investigations. "Havelwasser" is the first crime novel by the Brandenburg police officer Jean Wiersch.
