When my grandmother asked me to stay at her house while she recovered in the hospital, I didn’t hesitate. Her home was a place of warmth, filled with childhood memories and the scent of lavender. But before she left, she gave one chilling instruction: “Never open the locked room.”

The door was old, its brass knob dulled by time. I passed it daily, curiosity gnawing at me. What could be so dangerous, so sacred, that even I—her favorite grandchild—was forbidden?

Days turned into weeks. The house felt heavier, as if the locked room pulsed with secrets. One stormy night, unable to resist, I found the key tucked inside a hollow book. I unlocked the door.

Inside was a small, dim room. Dust floated in the air like ghosts. On the walls were photographs—dozens of them—of a young woman I didn’t recognize. Letters were stacked neatly on a desk, all addressed to my grandmother. They were love letters. But not from my grandfather.

The truth unraveled: the woman in the photos was my grandmother’s sister, who had vanished decades ago. The letters revealed a forbidden love between her and a man my grandmother had once loved too. Betrayal, heartbreak, and silence had followed. My grandmother had locked away the room—and the pain—choosing family loyalty over personal happiness.

When she returned from the hospital, I confessed. She didn’t scold me. She simply said, “Some doors stay locked not because of danger, but because of grief.”

That night, we sat together in the room, reading the letters aloud. She cried. I held her hand. And for the first time, the house felt lighter.
