Lucas Davenport has seen many terrible murder scenes. This is one of the worst. In the small Minnesota town of Deephaven, an entire family has been killed. There's something about the scene that pokes at Lucas' cop instincts - it looks an awful lot like the kind of scorched-earth retribution he's seen in drug killings sometimes. But this is a seriously upscale town, and the husband was an executive vice-president at a big bank. It just doesn't seem to fit - until it does and where it leads will only take Lucas into the darkest nightmare of his life.
