It's cold, it's December - and ex-cop Dennis Milne is intent on revenge. His best friend has been brutally executed, and Milne wants to know who did it - and why. But London is a dangerous place, especially for a man on his own. And although his former colleagues don't know Milne's back in town, it soon becomes clear there are people who do. And that they'll stop at nothing to get him out of the way. From the beaches of the Philippines to the mean streets of London, a hunt for justice becomes a terrifying battle for survival.
