The 17th thrilling entry in John Sandford's best-selling Prey series, Invisible Prey is a Literary Guild, Doubleday Book Club, and Mystery Guild main selection. On a deceptively quiet Minneapolis evening, Detective Lucas Davenport is summoned to one of the most heinous homicide scenes he's ever encountered. Two elderly women have been brutally bludgeoned inside their home, with only a few valuable yet common stolen items indicating the killer's sinister motives.
