A threat is called into the LAPD Bomb Squad and when tragedy ensues, the fragmented unit turns to Dick Stahl, a former Bomb Squad commander who now operates his own private security company. Just returned from a tough job in Mexico, Stahl is at first reluctant to accept the offer, but his sense of duty to the technicians he trained is too strong to turn it down. On his first day back at the head of the squad, Stahl''s three-person team is dispatched to a suspected car bomb. And it quickly becomes clear to him that they are dealing with an unusual mastermind - one whose intended target seems to be the Bomb Squad itself.

As the shadowy organization sponsoring this campaign of violence puts increasing pressure on the bomb maker and Stahl becomes dangerously entangled with a member of his own team, the fuse on this high-stakes plot only burns faster. The Bomb Maker is Thomas Perry''s biggest, most unstoppable thriller yet.
