I, Sniper book by Stephen Hunter

The explosive New York Times bestseller by Stephen Hunter that sends ex-Marine sniper Bob Lee Swagger into the thick of an FBI investigation and features some of the greatest gunfights ever to grace the page. It takes a seasoned killer… Four famed ‘60s radicals are gunned down at long range by a sniper. All the evidence—timeline, ballistics, forensics, motive, means, and opportunity—points to Marine war hero Carl Hitchcock. Even his suicide. The case is almost too perfect. …to hunt one. Recruited by the FBI to examine the data, retired Marine sharpshooter Bob Lee Swagger penetrates the new technology of the secretive sniper world to unravel a sophisticated conspiracy run by his most ruthless adversary yet—a marksman whose keen intellect and pinpoint accuracy rival his own. But when the enemy and his deadly henchmen mistake Bob for the hunted, it’s clear that some situations call for a good man with a gun…and the guts to use it. Published By Pocket Books on 2010-09-21
