I wasn’t searching for secrets when the photograph fell from my late mother’s album. But when I turned it over, I froze. It showed two little girls—one was clearly me at two years old. The other looked exactly the same. On the back, in my mother’s handwriting, were four words: “Nadia and Simone, 1978.” I had never heard that name in my life.

After days of searching through albums and finding no other trace of Simone, the truth became unavoidable. I drove to my aunt Phyllis’s house, and the moment she saw the photo, she broke down. She told me my father had had an affair—with her. Simone was her daughter. Later, my parents married, and I was born. When the resemblance became obvious, the sisters cut ties, and the secret was buried.

Simone grew up never knowing her father. I grew up never knowing I had a sister. My mother took the truth to her grave, leaving behind a single photograph she couldn’t quite bring herself to destroy.

At fifty, I finally met Simone. The resemblance was startling, but what surprised me more was how natural it felt. The truth didn’t heal the past—but it gave me something real in the present: a sister I never knew I was missing.
