Three hours later, two men in matching gray coats knocked on her temporary studio door. They didn't identify themselves. They asked for the key , which Anissa did not have, and the register , which she hadn't realized she’d found.

And somewhere inside her, the lost waltz began again—soft, clear, and just out of reach.

Anissa didn’t run. Runners attract eyes. She walked, steady and deliberate, through the rain, carrying a 400-year-old instrument and a secret she hadn’t asked for. Behind her, the villa’s cellar door swung open on its rusted hinges, and the loose brick lay on the floor like a dropped jaw.

“I thought it was a folk tune,” she said.

She told them she was just a conservator. The taller one smiled—a thin, rehearsed expression. “Ms. Colette,” he said, “you hummed the first bar of a lost waltz that four intelligence agencies have been chasing for seventy years.”
