Book excerpt: Loss and the infinite ways we attempt to come to terms with it permeate this absorbing psychological mystery set in the Finnish town of Turku. A week after his wife dies, Det. Kimmo Joentaa feels compelled to return to work to investigate the murder of a young woman smothered in her own bed while her husband was away. Only a valueless painting appears to have been stolen. A second murder, just as puzzling, occurs in a youth hostel where a young man is killed while others slept all around him.
