"Fans of Lawrence Block's Keller stories are going to love One More Kill. I certainly did. Matt Hughes kept me up all night, turning pages."
—George R.R. Martin

He was a trained killer, an orphaned kid who rose from raw recruit to the rank of major in the US Army Rangers. He was looking forward to retiring at the end of a thirty-year hitch, but when he developed a low-grade form of leukemia, the Army pushed him out and left him feeling alone and useless – until a fluke encounter with a rogue doctor tipped him into a new hobby: killing those who had done great harm and gotten away with it.
But then a police detective starts to dig into his "operations," while a vicious old enemy resurfaces with a scheme to draw the Ranger into a web of contract killing and gun running. Pushed too far, the Ranger means to solve his problems with bombs, bullets, and his own bare hands.
