She went to the kitchen and began taking things out for lunch, her hands moving through their familiar routine: pot on the stove, water on to heat, vegetables on the board.

Her birth certificate.

She kept it in an envelope in the small drawer of her bedside table with her other important documents. She knew exactly what it said. She had read it many times over the years, not because she needed to, but because it was 1 of the few official records of her mother’s existence that she had, 1 of the few places where her mother’s full name appeared in clean formal print.

Mother: Victoria Lawson. Father: unknown.

She stood at the kitchen counter and stared at the pot of water coming slowly to the boil.

Unknown.

That was the word that had sat in that small box on the form all her life, a box her mother had left empty. Whether out of bitterness or protection or simple resignation, Rebecca had never been entirely sure.

Unknown.

She picked up the knife and began cutting the vegetables. Her face was calm. Her hands were steady. But something was moving in her, something quiet and underground, the way water moves beneath a dry field long before it ever breaks the surface.

She did not know yet what it was. She only knew that Thursday felt suddenly closer than it had before.

Tuesday passed, then Wednesday.

The house kept its rhythm. Mr. Caleb worked. Rebecca cleaned, cooked, and moved quietly through the rooms. They exchanged the usual words: “Good morning.” “Lunch is ready.” “Thank you.” “Good night.”

Everything on the surface was exactly as it had always been.

But something beneath the surface had shifted.

Rebecca could feel it, though she could not have said precisely what it was. A change in the air, maybe. The way Mr. Caleb sometimes paused a half second too long before answering her. The way he occasionally looked up from whatever he was doing when she entered a room, not sharply, not suspiciously, just looking as if checking something, as if confirming something to himself.

She noticed it the way she noticed everything: quietly, without reacting. She stored it in the back of her mind and kept working.

On Wednesday evening, on the bus home, she took out her phone and looked at nothing for a while. Then she put it away and looked out the window instead.

She thought about Thursday.

She thought about the envelope in her bedside drawer.
