Algernon Blackwood was a writer of weird and occult tales. He was also a contemporary of Arthur Machen, both of whom were members of the Hermetic Order of the Golden Dawn. It was his interest in esoteric studies that likely served as the inspiration for stories such as this one. Two men decide to spend the night in a haunted barn, once inhabited by a practitioner of the Black Arts, where a malevolent spirit is known to possess and take control of the body of visitors. Featuring Blackwood's reoccurring character of Jim Shorthouse.
