Second Census

The visitor arrives politely enough. He carries credentials, asks questions quickly, and records the answers on a strange device that looks nothing like any Earth technology. Yet something about him is wrong. He moves too fast, recovers from impossible stumbles, and seems to know things about the residents that no census record could possibly contain. James Rainford only begins to understand the danger when the stranger reveals knowledge about his unborn children that even doctors could not yet know. Soon Rainford and his fellow scientists realize that the visitor is not merely gathering statistics. He is searching—methodically, house by house—for something hidden among humanity itself. What he finds could change where their loyalties truly lie. What begins as curiosity quickly turns into a desperate effort to trap the visitor before he disappears. But once they force the truth from him, the men must confront a far more unsettling discovery. The stranger’s mission does not concern Earth’s future. It concerns a war far beyond the Solar System—and the possibility that some of the combatants have been living quietly among humanity for years. John Victor Peterson wrote a small number of science fiction stories that appeared in mid-century American magazines. “Second Census” is his best-known work, a sharp blend of suburban life and interstellar intrigue. The story places advanced science, quiet domestic moments, and alien conflict side by side, producing a fast-moving tale where the biggest revelation arrives not from outer space but from the people who thought they were entirely human.
