Hypothermia
One cold autumn night, a woman is found hanging from a beam in her summer cottage. At first sight it appears to be a straightforward case of suicide. But when Karen, the friend who found her body, approaches Erlendur and gives him the tape of a sǎnce that the victim had attended, Erlendur embarks on an unofficial investigation to find out why the woman's life ended in such an abrupt and tragic manner. At the same time, he is haunted by the unresolved cases of two young people who went missing thirty years before, and, inevitably, his discoveries raise ghosts from his own past.
