My name is Sarah, thirty-two years old, married to Michael. Since the day we got married, we’ve lived with his parents, Thomas and Eleanor Brooks. It wasn’t something I ever found uncomfortable. In fact, I got along with my mother-in-law surprisingly well. She treated me like her own daughter. We went shopping together, went to the spa, talked for hours. Sometimes, when we were out, people even mistook me for her biological child.

But her relationship with my father-in-law was a different story altogether.

They argued often—quiet arguments, but heavy with tension. Sometimes she would lock herself in the bedroom and leave him sleeping on the couch. Thomas was a man of few words, always yielding, always silent. He often joked bitterly that after decades of compromise, he had long forgotten what it felt like to argue back.

Yet he had his flaws. He drank frequently and often came home late, sometimes not at all. Each time, my mother-in-law’s anger would erupt again. I used to think it was just the wear and tear of a long marriage.

My daughter, Emma, had just turned four. My husband and I didn’t want to send her to daycare too early, but with both of us working full-time, it became difficult. My mother-in-law had helped for a while, but I didn’t want to burden her forever.

A close friend recommended a private home daycare run by a woman named Grace. She only looked after three children, had cameras installed, and cooked fresh meals every day. I visited, observed, and felt reassured. So I enrolled Emma.

At first, everything was perfect. I often checked the cameras during work and saw Grace treating the children gently and patiently. Sometimes I picked Emma up late, and Grace never complained—she even fed her dinner.

Then one afternoon, while driving home, Emma suddenly said:

“Mommy, there’s a girl at teacher’s house who looks just like me.”

I laughed softly. “Really? Like how?”

“Like my eyes and nose. Teacher said we look exactly the same.”

I smiled, thinking it was just a child’s imagination. But Emma continued, very seriously:

“She’s the teacher’s daughter. She’s really clingy and always wants to be held.”

Something stirred uneasily inside me.

That night, I told my husband, but he brushed it off, saying kids often make things up. I tried to believe him.

But Emma kept mentioning the girl. Again and again.
