Storm Prey: Prey Series, Book 20 (hardcover) John Sandford
And this time, there's a storm brewing...Very early, 4:45, on a bitterly cold Minnesota morning, three big 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 swiftly 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.
Did she see enough? Can she identify them? Gnawing it over later, it seems to them there is only one thing they can do: Find out who she is, and eliminate the only possible witness...
