The investigators are drawn into a nightmarish sequel to an H. P. Lovecraft story that some have forgotten and others just assumed was over. It isn’t. In Arkham, there are horrors that have nothing to do with ghouls, ghosts, witches, or the Cthulhu Mythos. These monsters are all the more frightening because of their humanity and the lengths they will go to sate their inhuman appetites. Madness, murder, and mayhem are sure to follow, and investigators will have to overcome both supernatural powers and those given to people in authority by the laws of man. It all begins one misty night, on a lonely stretch of road between Dunwich and Arkham, with a horrible discovery.
