The hands were warm. Soft fingers, but flesh inflected with iron. Squeezing. The tongue lolled and protruded from the mouth. Vertebrae fragmented, one, two, three, until finally the hands relaxed and the limp body slid from their embrace. Blood turned to ice and sealed the nostrils. It's the week before Christmas. Catherine Berlin sits alone gazing at a bank of monitors, each capturing a slice of a vast industrial estate. A van appears: two men delivering crates, moving quickly. Her boss tells her to ignore them, but she can't. Berlin's scars have faded, but she still walks with a limp. She's broke and working nights as a relief CCTV operator, and looking for something more substantial. Her heroin habit is under control - only just. The night shifts end, but now Berlin herself is being watched. When an old friend offers her a job in Russia, she quickly agrees. The details are vague: a mysterious businessman with money to spend, a UK company offering a high fee for Berlin to investigate. Easy enough. But Berlin arrives in Moscow to find that her problems are only just beginning. She is soon forced to confront some uncomfortable truths about her past, and her present.
A body is found at the airport: a man clutching a sign with her name on it. Her pursuers reappear, and her guide, a Brit named Charlie, has secrets to hide. When Berlin's businessman goes missing, she realises that she cannot trust anyone or anything, if she is to survive.
