They Twinkled Like Jewels by Philip José Farmer is a science fiction short story, first published in 1954.
The story begins with Jack Crane lying in vacant lot. He seems a bit worse for wear, hiding from Bureau of Health and Sanity (Bohas) agents.
Jack Crane is trying to evade the authorities, but he isn’t succeeding too well. When he is finally arrested because of his homelessness, he is forced to go to a federal rehabilitation camp.
Along the way he meets an educated transient who explains to him about the high rate of schizophrenia and transients in the world. But the real problems start when he reaches the camp and comes into contact with a man who possesses something that Jack very much desires!
