The Echelon Vendetta by David Stone

A promising debut. PW: Despite a title that doesn't exactly roll off your tongue, this is a smoothly written spy thriller. Micah Dalton is a CIA "cleaner," the guy who wipes away the mess after something goes wrong in the field. When his good friend apparently commits suicide in a particularly gruesome manner, and then the man's family is murdered, Dalton discovers that someone is killing agents who have knowledge of a certain top-secret intelligence operation. Stone, a veteran intelligence officer writing pseudonymously, packs the novel with the kind of nitty-gritty detail that draws espionage fans.
