The story takes place over the span of a few hours during one night. The unnamed protagonist, a scientist working on extra-sensory perception, leaves work and walks toward home. He is haunted by perceptions of another world, and creatures in it who appear to be malevolent. Through flashbacks, it is revealed that he has accidentally uncovered evidence of a different and superior class of beings, which he calls "Superiors", who co-exist with humans but had previously gone almost undetected. He interprets his visions as reflections of an ongoing struggle in the Superiors' world and finds himself both attracted and repelled by what he sees.
Commentary
In The Worlds of Science Fiction,[2] the author wrote
It's quite unlike anything else I've done...I have no pretensions to being a Kafka or a Capek, but it did seem to me it would be interesting to use, or attempt to use, some of their techniques.
