Oh, Rats! by Miriam Allen De Ford is a gripping, atmospheric, and darkly clever piece of vintage science fiction that pushes a simple “what if” to its most unsettling extreme. When SK540—a laboratory rat engineered for extraordinary intelligence—begins to understand his captivity, his fears, and especially his hunger for power, his instincts evolve into strategy. He chooses not just to escape, but to lead. And once free, he brings with him only the meekest followers, the most obedient subordinates, and the most useful mates. His goal isn’t chaos. It’s control.
Philip and Norah Vinson, newly settled into a decaying old mansion, have no idea their home lies between SK540 and his vision of a new order. De Ford skillfully escalates tension through subtle signs: vanishing food, strange noises, and then the impossible—white laboratory rats acting with discipline and purpose. The suspense grows as the couple realizes they’re not facing vermin. They’re facing a coordinated mind whose intelligence rivals their own, and whose motives are hidden beneath twitching whiskers and silent communication.
The story sits at the crossroads of science, ethics, and fear. What happens when a creature gains human-level intelligence but retains animal instinct? What is morality to a mind shaped entirely by survival, opportunity, and hierarchy? De Ford never resorts to spectacle; instead, she demonstrates how power shifts quietly, and how human certainty can crumble under the weight of something small, numerous, and relentlessly strategic.
Miriam Allen De Ford was a remarkable and versatile American writer whose career spanned more than half a century.
