The Salzburg Capuchin monastery has opened up to the world: self-finding seminars are intended to bring secular finances into the monastery walls and an archaeological excavation is to uncover the final resting place of a legendary Bavarian Duchess with valuable additions. But instead of a treasure, the skeleton of a British pilot who crashed in World War II appears. The injury to the skull is a bullet hole – it was executed. And then the body of Brother Gereon is discovered in the excavation section the next day. The young, dogmatic monk had spoken out against an excavation in the monastery. Since Palfinger is the main investigator on a cure, it is up to District Inspector Irene Russmeyer, her Bavarian colleague Hubert Mur and Hofrat Seywald to investigate past war crimes and the murder of Brother Gereon.
