The investigators in this story are different from those in most Cthulhu adventures as they are not mere ignorant innocents who stumble into danger. This band of brittle, insanity-plagued veterans has survived many forays against the Cthulhu Mythos. One of their number, Doctor Vincent Cannady, has been notified of the death of his father and is returning to his Pennsylvania home to put the family affairs in order. The other investigators have decided to accompany him in hope of enjoying a relaxing vacation.
