Man In The Moon

When a young computer genius out of the small town of Elroy,
Wisconsin discovers a way to modify data from the Human
Genome Project to create the perfect DNA, a double agent
whose allegiance has always gone to the highest bidder is lured
out of semi-retirement by the opportunity of a lifetime. Now this
aging professional, once at the top of his game, will again meet
his CIA nemesis in a fast-changing world populated by a much
younger, and smarter, generation.
To get his hands on the greatest discovery the scientific world
has ever known, he's going to have to up his game. But years of
solitude, paranoia, isolated stakeouts and endless hotel rooms
have taken their toll. As he wrestles with the knowledge that he
is losing his professional edge, and maybe his grip on reality, the
most difficult decisions of his life begin with a mysterious third
player who would dare try to beat two old lions to the kill.
