When a mummified Viking corpse is discovered in a crevasse out on the edge of an ice sheet, journalist Matthew Cave is sent to cover the story. The next day the mummy is gone, and the body of the policeman who was keeping watch is found naked and flayed - exactly like the victims in a gruesome series of murders that terrified the remote town of Nuuk in the 1970s. As Matt investigates, he is shocked by the deprivation and brutal violence the locals take for granted. Unable to trust the police, he begins to suspect a cover-up. It's only when he meets a young Inuit woman, Tupaarnaq, convicted of killing her parents and two small sisters, that Matt starts to realise how deep this story goes - and how much danger he is in.
