From First Blood to The Fifth Profession, New York Times bestselling author David Morrell has delivered more high-octane thrills than any writer of his time. Here he shows his readers the secrets of real-life covert operators—and takes action to a whole new level.

Know him. See him. Stop him—or die. No one knows his real name or where he lives. Trained by Delta Force, calm in moments of absolute terror, Cavanaugh works as a protector for those rich enough to afford him and his team, stopping threats before they strike—silently, swiftly, and lethally. His latest assignment is to protect a brilliant scientist named Prescott, who has a secret so extraordinary he needs to disappear and adopt a new identity. For Cavanaugh, helping Daniel Prescott is just another job. Then it explodes, Prescott vanishes, and the protector finds himself in a fast, furious battle for his life.
