Requiem for an assassin

"For assassin John Rain, getting out of the killing business was never going to be easy. But with a new identity in Paris, and the help of his lover, Mossad agent Delilah, he was beginning to leave the killing business behind. And then he receives a message from rogue CIA operative Jim Hilger: We have your friend Dox. Do as we tell you, or the former Marine sniper dies."--Publisher description.
