Dengler’s mother is getting old, she starts seeing shadows in the yard at night. When Dengler arrives to reassure her, he realizes that either he has gone mad too or there really are figures moving around out there.
Dengler's family owns a piece of land which happens to be the ideal location for a wind turbine – if it weren’t for the local opposition. When the spokeswoman for the protesters is found murdered, Dengler finds himself confronted with a complicated case – professionally as well as personally: the victim was his childhood sweetheart. The more progress Dengler makes in his investigation, the more clearly the murder brings to light an impenetrable web of obligations and bloodily enforced interests. Corrupt state politicians, greedy businesses, the nuclear lobby, and a Russian honorary consul are all mixed up in the case, and the connections reach all the way up into the highest echelons of power – and many decades into the past.
