Avenger

From the author of The Day of the Jackal comes Frederick Forsyth's Avenger, a heart-stopping thriller of murder, intrigue, deception, and revenge.
Attorney Calvin Dexter hangs his shingle in a quiet New Jersey town, has a reasonably successful practice, and takes the hills strong while triathlon training. But Dexter is no ordinary lawyer. On Sundays, he reads the paper and shuffles around his dark, empty house, trying to forget about a life he has lost forever.
Until, of course, Dexter reads something in the papers that sends him the necessary signal. Until one of the handful settle a score like Cal Dexter can.
But the game is changing, and this time CIA agent Kevin McBride must find a way to stop Dexter before his quest for vengeance throws the world into chaos.
