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.
