This book was written in 1957. The story here had an interesting genesis. It was first made into a thirty minute television show, then developed into a film(The Atomic Man in America, Time-Slip in England) in 1955, then finally the novel a couple of years later. Mike Delaney spots a photo of a man, barely alive, pulled from the Thames, with two bullets in his back. He recognizes the man as Dr. Stephen Raynor, an American scientist he'd interviewed a couple of years before. There was a mysterious fog around the body, dismissed as bad film by the police. The dust cover is in rough shape but the book is in good condition.
