Three independent narratives linked together by the device of a narrator discovering notes left by a deceased relative. Piecing together the whole truth and disturbing significance of the information he possesses, the narrator's final line is ''The most merciful thing in the world, I think, is the inability of the human mind to correlate all its contents.'' One of the most intersting early 20th century scifi stories. I enjoyed learning about some archaic english words Lovecraft uses throughout the story. It is also also quite an innovative story when you consider the time this was written and the `newness` of the scifi genre at that time. A must read for every scifi aficionado.
