Two men, vacationing in Ireland, come upon a great ruined house, where they find an ancient manuscript. Its author tells a strange tale; transported through unfathomable immensities of space, he comes across an "anti-house," precisely like his own, hwere strange and evil creatures seek to enter. Back on earth, the same grotesque horrors appear; besieges, he seeks to escape. The horror builds. And now something even stranger occurs: time itself goes mad, centuries pass in instants, the sun is swallowed by the central sun of the universe, a great sentient star that emits a curious violet light, and sends thought messages everywhere - messages of infinite sadness, for the forces of evil are great.
