Certain prey

by John Sandford

Lucas Davenport confronts an entirely new kind of adversary in this harrowing "Prey" novel. Her name is Clara Rinker, an attractive, pleasant Southern woman--the best hitwoman in the business. But when she's hired for a job in Minnesota and a witness survives, that's when Davenport gets on her case--with no idea of the toll that it will take on him.
