The Echelon Vendetta (Unabridged‪)‬

CIA agent Micah Dalton is a "cleaner." He takes care of other agents' mistakes. When a friend and mentor commits a grotesque suicide, Dalton's investigation leads him into the snare of a madman, into the arms of a beautiful, mysterious stranger-and into a conspiracy within his own agency. Dalton knows only one thing for certain-this job is going to get very messy.
