Three independent narratives linked together by the device of a narrator discovering notes left by a deceased relative.

Lovecraft regarded the short story as "rather middling—not as bad as the worst, but full of cheap and cumbrous touches". Weird Tales editor Farnsworth Wright first rejected the story, and only accepted it after writer Donald Wandrei, a friend of Lovecraft's, falsely claimed that Lovecraft was thinking of submitting it elsewhere.The published story was regarded by Robert E.
