Robert Ludlums The Janson Command (পেপারব্যাক)

Summary of the Book
Paul Janson has retired from his life as a covert operative and assassin for the US government. His new mission is to take only those jobs he believes will help the world in a positive way. For this purpose he finds himself working with Jessica Kincaid, a sharpshooter who doesn't miss. Now he needs to find a doctor who has been kidnapped by African pirates, and the kidnap has occurred on international waters. He realizes that there's something much more clandestine going on in the background, and if he doesn't rescue the doctor in time, he will lose a lot more than he bargained for.
