May 1945. The Second World War has been over for a few hours when Inspector Druwe is called to the naval base in Flensburg in northern Germany. He is asked to help set up a new police unit. Then he receives some strange news – from Werner Grell, a secret service agent who has gone underground. Grell tells him about explosive material he got from the former head of military intelligence, Wilhelm Canaris, on major figures in the Nazi party as well as leading industrialists. Hesitantly, Druwe confides in the British military. They appear extremely interested, but the first secret meeting between Grell and a captain in the British military ends in disaster when both are found dead in a warehouse. It looks like they shot each other – but Druwe has his doubts.

In the second novel in this crime series, Inspector Druwe investigates a double murder – and ends up once more caught in the middle.
