Many men have systems which they claim can influence the fates or lucky items that help life go their way; the difference is Watson can actually do it. Unable to resist a puzzle, he stumbles on an unthinkable conspiracy which may destroy the world as we know it. Can even his gift stand against the forces arrayed against him?
