Martin Peters finds himself in Berlin. Once a British spy involved in a controversial loyalist shooting in Belfast, he spent time in Berlin infiltrating the Punk scene just before the Wall came down. Now in his thirties, he is a detective in the local police force.
He is struggling - two naked headless corpses were dredged from the Havel river. There are no clues apart from a single word tattooed in Cyrillic on their left arms and the fact they were found a week apart after Christmas at exactly the same spot.
Visiting his favourite swingers club, the seedy Der Zug, he comes across the bloated Lothar Blucher. Pressing his former Cold-War informer for help, Peters is instead led to a video showing the horrifically violent murder of a man tied to a chair. Not long after, a former girlfriend, Heike, gets in touch. She has received the same video - and rapidly the dead bodies start piling up at the hands of a demonic serial killer.
With crimes darker than The Killing and The Bridge, you will be riveted by this gripping Martin Peters story set in Berlin, Belfast and London.
