Very early, 4:45, on a bitterly cold Minnesota morning, three men burst through the door of a hospital pharmacy, duct-tape the hands, feet, mouth, and eyes of two pharmacy workers, and clean the place out. But then things go bad. One of the workers dies, and the robbers hustle out to their truck and find themselves for just one second face-to-face with a blond woman in the garage: Weather Karkinnen, surgeon, wife of an investigator named Lucas Davenport. Can she identify them? It seems to them there is only one thing to do: Find out who she is, and eliminate the only witness.
