"In the latest novel from New York Times bestselling author Linwood Barclay, a teacher's act of heroism inadvertently makes him the target of a dangerous blackmailer who will stop at nothing to get what he wants"-- Provided by publisher.

How would you react in a life-or-death situation? It’s a question everyone asks themselves, but few have to face in real life. English teacher Richard Boyle certainly never thought he would find himself talking down a former student intent on harming others, but when Mark LeDrew shows up at Richard’s school with a bomb strapped to his chest, Richard immediately jumps into action. Thanks to some quick thinking, he averts a major tragedy and is hailed as a hero, but not all the attention focused on him is positive. Richard’s brief moment in the spotlight puts him in the sights of a deranged blackmailer with a score to settle. The situation rapidly spirals out of control, drawing Richard into a fraught web of salacious accusations and deadly secrets. As he tries to uncover the truth he discovers that there’s something deeply wrong in the town--something that ties together Mark, the blackmailer, and a gang of ruthless drug dealers, and Richard has landed smack in the middle of it. He’s desperate to find a way out, but everyone in his life seems to be hiding something, and trusting the wrong person could cost him everything he loves.
