Friday, rush hour. Martin Gregory just manages to catch the 4:48 train. Tomorrow is his wife's birthday and he plans to devote the weekend to her and their beloved dogs. But when he rises in the morning, Martin does something so horrific, so inexplicable, and so out of character that his only option is to run. A lost horror classic back in print at last, The Watcher chronicles Martin as his quest for understanding plunges him through shifting realities and twisted corridors of time, and into the deepest recesses of the human mind.
