''Historical crime fiction at its best' Chris Lloyd, author of The Unwanted Dead

''One of the UK's finest crime writers' Ben Kane, Sunday Times bestselling author of Napoleon's Spy

September 1939. A city ruled by fear. A population brutalised by restrictions and reprisals. Amid the devastation, another hunter begins to prowl. What are a few more deaths amid scores of daily executions?

Former chief investigator Jan Kalisz lives a dangerous double life, forced to work with the occupiers as he gathers information for the fledgling Polish resistance. Even his family cannot be told his true allegiance.

When the niece of a Wehrmacht general is found terribly mutilated, Jan links the murder to other killings that are of less interest to his new overlords. Soon, he finds himself on the trail of a psychopathic killer known as The Artist. But, shunned as a Nazi collaborator, can he solve the case before another innocent girl is taken?

A chilling serial killer investigation, perfect for fans of Simon Scarrow''s Blackout and the TV series Hannibal starring Mads Mikkelson.

With this book, Jackson will rightfully be regarded as one of the UK's finest crime writers' Ben Kane, Sunday Times bestselling author of Napoleon's Spy

'A taut, tense thriller... Gutsy and gripping, this is perfect for fans of Chris Lloyd and Robert Harris' D. V. Bishop, author of City of Vengeance
