With his face swaddled in bandages, his eyes hidden behind dark glasses and his hands covered even indoors, Griffin the new guest at The Coach and Horses is at first assumed to be a shy accident-victim. But the true reason for his disguise is far more chilling: he has developed a process that has made him invisible, and is locked in a struggle to discover the antidote. Forced from the village, and driven to murder, he seeks the aid of an old friend, Kemp. The horror of his fate has affected his mind, however and when Kemp refuses to help, he resolves to wreak his revenge.
