1947. Threadbare London endures the bleakest, coldest winter for decades. Food rationing is worse than during the war. Coal supplies run out. The Thames freezes over.

Against a background of black ice, blackouts and the black market, agent Peter Cotton is seconded to Operation Sea-snake. MI5 is in the grip of civil war; MI6 is riddled with traitors. Unsure who to trust - or even who is pulling the strings - Cotton, ever the outsider, must protect an atomic scientist caught up in a vicious homophobic witch-hunt, limit the damage caused by a bully-boy MP, rely on a rent-boy informer and, despite the murderous attentions of a couple of Glasgow razor boys, embark on a ruthless hunt of his own.
