Phantoms of Breslau - Marek Krajewski

Breslau, 1919. The hideously battered bodies of four young sailors are discovered on an island in the River Oder. When Inspector Mock arrives at the scene to investigate, he discovers a note addressed to him, asking him to confess his sins and to become a believer.

As he endeavours to piece together the elements of this brutal crime, Mock combs brothels and drinking dens of Breslau and is drawn into an insidious game by the murderer; ultimately he uncovers a secret society which appears to have the Inspector himself in its sights.
