Golden Prey: Prey Series, Book 27 (hardcover) John Sandford
Thanks to some very influential people whose lives he s saved, Lucas Davenport has a new job. He is a U.S. marshal, but not just any marshal one with unusual scope. He gets to investigate whomever he wants, wherever he wants, across the country, and once in a while, he might be called upon for special cases. How special? They couldn t come from anyone higher.
But his first case is something different. A rash of audacious robberies reminds Davenport of a criminal he once chased several years ago, the leader of a gang focused only on large cash crimes, and who didn t mind leaving bodies behind. The last time he was heard from, a shootout left two FBI men dead, and now Davenport thinks the leader might be back.
Davenport knows this is the kind of investigation he s been hired to pursue, and he knows something else as well: This could get ugly fast . . . so he d better be up to it."
