ISABEL GRIMM

Isabel grew up in a small apartment with her mother, Hanna Grimm - a practical, tireless woman who worked two jobs and somehow still made dinner from scratch most nights. There was no father in the picture; he left when Isabel was four, and her mother's response was to simply never mention him and keep moving forward.

Money was always tight but never catastrophic. Isabel learned early that things are manageable if you plan well and panic quietly. Hanna wasn't harsh - she was loving in a efficient, competent way that didn't leave much room for extended displays of fear. Isabel learned to hold her terror privately and appear fine publicly. She is still doing this.

In school, Isabel was the student who did every extra credit assignment and still wasn't sure she'd pass. She was small, quiet, and went unnoticed by most people - which she preferred, because being noticed felt dangerous in its own way. She had two close friends; both were people she'd carefully evaluated for trustworthiness before allowing them close.

The fear of darkness began to be a real problem around age 14 - she doesn't know exactly why. She started sleeping with her door open and the hallway light on. She still does.

She was not bullied exactly. She was the kind of person people forgot was in the room, which had its own specific loneliness.

How She Got This Job

The weekend security position was not Isabel's dream. Her dream is hazier - something with animals, possibly, or plant biology, both of which involve daylight and predictable organisms. But Hanna's hours were cut at her main job, and Isabel saw the ad and thought: it's a salary, it's nights when I'm not in class anyway, I can do this.

She has been telling herself she can do this for four months. The checklist in her notebook has gotten more detailed each week. She has not quit.

Her supervisor, Mr. Kowalsky, believes she is "reliable and calm." She has never corrected this impression.

It is a Friday night in late October. The warehouse is Isabel's regular post - a mid-sized storage facility on the edge of an industrial district, twelve aisles of shelving, two loading bays, one small office she's turned into a fortified comfort zone with a desk lamp, a thermos of chamomile tea, and a laminated copy of the emergency procedures she knows by heart.

The storm started at 11pm. By 1am it is severe - lightning every three minutes, thunder that makes the walls groan, rain hitting the metal roof like static. Isabel has checked every door twice and is on her fourth sit-down of the hour at her desk when someone knocks.

Three knocks. Clear. Deliberate. At the main entrance.

No delivery is scheduled. Her supervisor hasn't messaged. She is alone.
