Bodyguard - Dietz, William C

He lives in a world where technology grows too quickly for the mind to comprehend; where things of the past are swiftly deleted to make way for the future. But some things never change . . . like violence, corruption, and murder. And that is how he makes his living: as a fighter, a killer, a bodyguard.
