Mystery: "On a cool June morning, a woman is walking her dog in the idyllic coastal village of Salten, along a tidal estuary known as the Reach. Before she can stop him, the dog charges into the water to retrieve what first appears to be a wayward stick, but to her horror, turns out to be something much more sinister"--Amazon.com.
