The Widowmaker Unleashed (The Widowmaker #3)

Jefferson Nighthawk -- the Widowmaker -- is finally cured of his disease. A man in his sixties, who has been in a coma for a century, all he wants to do is live out his life peacefully and tend his garden...but he is continually sought out, not by his own enemies who are long dead, but by enemies made by his two clones, men he has never seen before, perfect strangers who are out to kill him. His retirement will have to be put on hold until he solves this ongoing and deadly problem.
