Polt.

"Much has changed for Simon Polt, a retired gendarmerie inspector. He's embarking on new career paths, and his future with his long-time girlfriend, Karin Walter, suddenly took on a completely new perspective. Polt has little contact with the police, who now watch over the small villages in the Wiesbach Valley—his only friend is Norbert Sailer, a law enforcement officer who's just his style. But the discovery of a stranger's body completely disrupts Simon Polt's quiet world: No one claims to have known the dead man, but some seem to know more about him than they're willing to admit to the police."
