On August 23, 2006, Roberto Campos left his home in the Lindavista neighborhood of Mexico City to go to work, just as he did every morning. He kissed his wife Patricia on the forehead, gently ruffled the hair of his two children who were eating breakfast at the table, and closed the door behind him. That was the last time his family ever saw him.For 17 years, Patricia Ruiz lived with the pain of not knowing what had happened to the man with whom she had shared 12 years of marriage. The police investigated, the family searched, neighbors speculated, but Roberto had simply vanished—like smoke dissolving into the air of a city with 20 million inhabitants.

Then, one morning in September 2023, Patricia walked into a bank branch in the southern part of the city to take care of a routine errand, and her world came to a sudden stop. The man standing three people ahead of her in line had the same posture, the same gestures, the same way of scratching the back of his neck that Roberto had.When the man turned slightly and Patricia saw his profile, her heart jolted so violently that she had to lean against the wall. He was 17 years older, with more gray hair and deeper wrinkles, wearing glasses he never used to wear. But it was him. It was impossible. It was unreal. But it was Roberto.
