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 an awkward encounter at a party thrown by the head of the police force, and by a colleague's spiral into the depths of a gambling addiction. "Light in a Dark House" is an atmospheric, haunting and beautifully written psychological crime thriller from an award winning crime writer.
