Vanish — Steve Elliott

Meet David, an average policeman, just trying to survive from day to day. He's seen some strange things in his life, but none so strange as Vance (who prefers to be called 'Vanish'), a hardened and suspicious street kid who claims to have witnessed a monster dragging the members of a drug syndicate into a black cloud and then disappearing. David then enlists his cynical partner, Carl, in an effort to solve this mystery. They are led to Mel, a magic practitioner, who announces he knows how to track and kill the mysterious creature. However, first of all, they have to uncover a specific jewel, lost for generations. They eventually do so, thanks mainly to the wily Vanish who has an incredible eye for detail. Following Mel's lead, they confront the magical creature and his makers. This results in a major battle, with the fate of the city depending on its outcome.
