When a mummified Viking corpse is discovered on an ice sheet in Nuuk, Greenland, journalist Matthew Cave is sent out to report on the extraordinary finding. When he returns to the site the next day, the mummy has disappeared and the body of the policeman who was keeping watch is found naked and flayed on the ice, resembling a gruesome series of unsolved murders from the 1970S. With no faith in the police, the only person Matthew dares to trust is a young Greenlandic woman who, at fifteen years old, was charged with killing her family in the same shocking manner.
