I'll Kill You Tomorrow

I'll Kill You Tomorrow is a science fiction short story by Helen Huber first published in 1953 in the magazine If Worlds of Science Fiction.

Set almost entirely inside a city hospital, it transforms a routine night shift into a quiet, escalating nightmare.

On duty in the maternity ward, a young nurse becomes uneasy when she notices an unnatural, complete silence in a room filled with newborn babies. Her checks reveal that the infants are alive and well, but behind their calm, unblinking gazes lurk malevolent, bodiless entities that have slipped into this world to use them as hosts. These invaders are patient parasites, planning to grow alongside their tiny carriers until they can one day act as perfectly placed human assassins.

Together with a sympathetic young doctor, the nurse searches for a way to fight an invisible enemy hidden inside innocent lives. Their desperate plan pits human compassion and medical ethics against a threat that demands drastic action, forcing them to confront whether it is ever right to end potential lives now in order to save countless others in the future.

Huber uses the confined hospital setting, clinical details, and tense dialogue to create a suffocating, slow-building suspense, where every quiet crib and dark corridor might conceal cosmic danger. Beneath the horror, the story raises disturbing questions about corrupted innocence, moral responsibility, and the possibility of evil hiding in the most ordinary places, leaving a lasting sense of unease long after the final page.

"It was not a sinister silence. No silence is sinister until it acquires a background of understandable menace. Here there was only the night quiet of Maternity, the silence of noiseless rubber heels on the hospital corridor floor, the faint brush of starched white skirts brushing through doorways into darkened and semi-darkened rooms.
But there was something wrong with the silence in the "basket room" of Maternity, the glass-walled room containing row on row, the tiny hopes of tomorrow. The curtain was drawn across the window through which, during visiting hours, peered the proud fathers who did the hoping. The night-light was dim.
The silence should not have been there."
