The digital shadows of the file by J. J. Fernández flickered on Inspector Marco Valenti’s screen. In the world of cybercrime, the deadliest weapons weren't knives; they were lines of code designed to vanish after execution.
"He didn't break in," Valenti whispered to his partner, Elena. "He tuned in."

The screen went black. The file vanished. Valenti looked at the empty folder and realized that in the digital age, the perfect crime isn't one where you don't leave a trace—it’s one where the trace itself never existed.
He opened the decrypted file. Inside wasn't a confession, but a sequence of commands tied to the mansion’s smart-home system.
