This is the third Dan Connor mystery.
Dan is planning to go on a nice, long vacation with Claire, his partner, when his superiors order him to go to the North Woods, in order to solve a series of murders. Walker, his sidekick, is already involved.
There's an oil pipeline going through, and someone is killing people attached to it. The main suspect is an Indian boy, who seems to have some sort of disorder on the autism spectrum. Most of the principals almost get themselves killed, and there's some pretty good suspense. I found the solution a bit unsatisfying, though.
Some of it is quite good, but it is infested by PC.
