Acclaimed for the depth and breadth of his fictional universe, best-selling SF and fantasy writer Simon Green is the author of the popular Twilight of the Empire and Deathwalker series. In Ghost of a Smile, the Ghost Finders answer a desperate call for help from one of the world's biggest drug companies. A team of police enforcement agents has already disappeared, and the Ghost Finders have no idea how to proceed. But they'd better figure something out fast, because time is running out-and failure means an entire building full of innocent victims will cease to exist.
