She opened it last, the way you opened the thing you were most afraid of last because the structure of working toward it felt like preparation.It contained three files.FILE 1: A video. Arjun, in what appeared to be his London flat — she recognized the kitchen, the blue tiles — speaking to the camera. Dated October 29th, five days before the crash.She played it.His face. His voice. The specific cadence of a man who had rehearsed something and was executing the rehearsal with the seriousness of a person who knew he might not get another chance.He said: "Naina. If you're watching this, the worst version happened. I'm going to tell you what I know and what to do with it. Don't skip ahead — watch this in order."She watched it in order.FILE 2: A set of contacts. Real names, encrypted behind a key that she recognized immediately — her police ID number, reversed. He had known she would find this. He had built the key for her.Three contacts. A name in Tokyo. A name in Dubai. A name in Geneva.FILE 3: One line of text.

London, then Heathrow. Nine possible flights." She pulled up her notes. "What's the signal he means?"Rohan thought for a moment."He mentioned something," he said. "A protocol he'd set up. He said if he ever needed to communicate without using any channel that could be monitored, he had a way." He paused. "He called it dead drop digital — a message hidden not in a communication but in a data pattern. Something that looked like noise to anyone watching but was a signal to someone who knew what to look for." He paused. "The phone pings."She looked at him."The pings are the message," she said."The pattern of the pings," Rohan said. "Not the locations. The timing. He would have set it up to transmit a pattern in the intervals between location signals. Morse, or something similar."She pulled up the phone tracking data she had been sent by Thames Valley Police — the official data, showing the phone's location history before it had gone dark.She looked at the timestamps.She looked at the intervals.She opened a Morse code chart.It took her twenty minutes.The pattern, decoded, was three letters:
T-Y-OTokyo.
