Keeping His Promise: Supernatural Fiction Series (Unabridged‪)‬

Algernon Blackwood was a writer of weird, occult, and ghost 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 strange stories such as this one. In this tale Blackwood tells the story of a student up all night studying for his exams when a childhood friend he hasn't thought about in many years unexpectedly pays him a visit.
