Finnish detective Kimmo Joentaa is called to the local hospital in which his young wife died several years before. An unidentified woman in a coma has been murdered by someone who wept over the body, their tears staining the sheets around her. The death marks the start of a series of killings, with the unknown patient at their centre. As autumn turns to winter, and Christmas fast approaches, Kimmo s attempts to unravel the case and identify the first victim are complicated by the disappearance of his sometime girlfriend, who has vanished after a party thrown by the head of the police force, and by a colleague s spiral into the depths of a gambling addiction.
