John wrote this one-act play in 1960. It was one of his few excursions into science fiction, and it’s thoroughly dystopian. After a nuclear holocaust, a few survivors huddle in a dark cave. They complain about the cold and dark, reminisce about life under sunlight, and prepare to hunt rats as the rats hunt them. Another survivor joins the group, and they greedily devour the small bag of termites she’s managed to find. A firefly makes its way into the cave, and they marvel at its dazzling light, “a sun of our own”—except for the youngest of the group, who is blind. Here’s the first couple of pages.
