They met by chance in Madrid, among the shelves of the old Biblioteca Nacional de España, where the “book” dust and silence smelled of knowledge, and they got into an argument about a book. Later, they both realized that their first meeting was not accidental—it was a gift of fate. Six months later, they were still arguing about books, sharing coffee in the morning, and returning home by different routes, but with the same feeling—as if something important had already happened in their lives.
Katherine is a tall, as they say, “fat” American with an open smile and a laptop under her arm. She came to study at the country's best private university, IESE Business School at the University of Navarra. Oliver is a thin Norwegian of average height who studied biology at the Autonomous University of Madrid.
Two years of friendship, quiet walks, funny videos, and long conversations passed. One day, Oliver rented an old but surprisingly beautiful, renovated house in a cozy place where he could study and keep a diary about the biological life of Mediterranean fauna. He invited Katherine, and she agreed. When she arrived, it suddenly started raining cats and dogs. Soaked to the skin, they took shelter in the kitchen.
Looking around the room, Katherine noticed an open compartment in the cabinet. Among the yellowed newspapers, empty cans, and boxes lay a pizza box. It looked a little different. On the cardboard lid of the box were strange markings in marker, rows of symbols. Oliver waved it off and went to get towels.
When he returned, Katherine gestured to him and whispered, “These aren't random scribbles, they're the password to a crypto wallet.” They had no idea if this wallet even existed. But when they checked the account, they found a real treasure. The pizza box with blue marker writing contained 421 bitcoins.
They decided to investigate the history of this account and did a little digging into the history of this old house and learned the truth: a criminal had once been hiding here. In 2015, he was killed in a shootout with police on the other side of the island. After that, the house stood locked for ten years, silent and forgotten by everyone. So, the wallet no longer had an owner.
Katherine and Oliver eventually got married. They bought the house and left the box on the same shelf as a reminder.
