Lucas Davenport tracks a prolific serial killer in this nail-biting #1
New York Times
-bestseller from John Sandford.
Clayton Deese looks like a small-time criminal, muscle for hire when his loan shark boss needs to teach someone a lesson. Now, seven months after a job that went south and landed him in jail, Deese has skipped out on bail, and the U.S. Marshals come looking for him. They don't much care about a low-level guy—it's his boss they want—but Deese might be their best chance to bring down the whole operation.
Then, they step onto a dirt trail behind Deese's rural Louisiana cabin and find a jungle full of graves.
Now Lucas Davenport is on the trail of a serial killer who has been operating for years without notice. His quarry is ruthless, and—as Davenport will come to find—full of surprises . . .
