Red

"Paul Moses was quietly retired--until his former employers decided he was too dangerous to live. But while the CIA might have forgotten his training, Moses hasn't. When a kill team interrupts his solitude, he changes his status from green to red. As thebodies pile up, the men who set this ruthless killer back into action sit safe in their Langley offices. At least, that's their intention--Moses has a different plan"--Publisher description.
