Max Heller’s fourth case
The spy inside your own borders
In late summer 1951, Detective inspector Heller and his family are returning to Dresden from their state-authorized vacation on the Baltic Sea. His wife Karin will be leaving again immediately, having unexpectedly received permission to visit their son Erwin in West Germany.
Heller is worried, but his new case isn’t leaving him any time to brood. Two men, Jehovah’s Witnesses, being held under suspicion of espionage die in their prison cells. And other mysterious deaths follow. A cryptic message is found next to one of the victims and a horrifying suspicion rises in Heller.
