The latest installment in the Crime Writers' Association Gold Dagger Award-winning Reykjavik Murder Mystery series. 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; the woman, María, had never recovered from the loss of her mother two years earlier and had a history of depression. But when Karen, the friend who found her body, approaches Erlendur and gives him the tape of a séance that María had attended, his curiosity is aroused. Driven by a need to find answers, 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
