Devil's Maintenance

What would the U.S. government do if they actually caught the Devil? Where would they keep him? What would they do with him? If they used him, what would the cost be?
In an abandoned nuclear submarine buried beneath the Greenland ice shelf, the National Security Agency’s new Information Assurance Technical Director, Ray Peterson, is revealed the greatest secret the U.S. government has ever kept. Daniel Edgar Vincent Ivan Liberty, codenamed Devil, has an intellect so vast, there is no puzzle he can't solve, no computer system too complex to create or control, and the thing he enjoys most is manipulating the fleeting lives of human beings.
Devil surrendered to the U.S. government of his own free will, only requesting that he be kept alive in a prison of his design near the Arctic Circle in exchange for his gifts to be utilized exclusively for America….and for a terrible price that Ray will soon horrifyingly discover!
