The Wanted book by Robert Crais

When single mother Devon Connor hires private investigator Elvis Cole, it’s because her troubled teenage son Tyson is flashing cash and she’s afraid he’s dealing drugs. But the truth is devastatingly different. With two other partners in crime, he’s been responsible for a string of high-end burglaries, a crime spree that takes a deadly turn when one of them is murdered and Tyson and his girlfriend disappear.

They stole the wrong thing from the wrong man. Determined to get it back, he has hired a team that is smart and brutal, and to even the odds, Cole calls in his friends Joe Pike and Jon Stone. But even they may be overmatched. The hired killers are leaving a trail of bodies in their wake. A few more won’t make any difference.
