"Left-side preference," she said to Raghav. "The photographer always positions themselves to the left of the subject. That could be a handedness thing — right-handed people naturally hold cameras to their right eye, which frames subjects on the left."
"Narrows the field to ninety percent of the population."
"But combined with the height and the distance, it gives us a physical profile. Tall, right-handed, consistently at the same distance. They're using the same camera — the depth of field is identical across all photos, which means the same lens, the same settings."
"Can you identify the camera?"
"Not definitively, but the image quality and the depth-of-field characteristics are consistent with a specific range of smartphone cameras. Not flagship — the resolution isn't high enough. Mid-range. Possibly a Realme or a Redmi. The kind of phone that ten million people in Delhi own."
Raghav's team ran the photographs through a location-matching algorithm. Every identified location was in South or Central Delhi — Hauz Khas, Khan Market, Connaught Place, Sarojini Nagar, Shahpur Jat. A geographic cluster.
"The Watcher lives in South Delhi," Isha said. "Or works there. The photographs are taken at different times of day, which means they're not concentrated around a commute. This person has flexible time — they're wandering, observing, choosing subjects during leisure hours."
"Self-employed? Freelance? Student?"
"Or unemployed. Someone with time and proximity and a reason to be in these areas without drawing attention."
The second thing she noticed: the ratings. She'd established that they correlated with isolation. But there was a secondary pattern — the subjects rated above 8 were all photographed in moments of solitude. Not just alone — specifically in moments where they were disconnected from the world around them. Looking at a phone. Reading. Lost in thought. The high-rated subjects were captured in their most private public moments — the moments when they were physically present but mentally absent, when they'd retreated into their inner world and were, for a brief instant, unreachable.
The Watcher wasn't just scoring vulnerability. They were scoring disconnection. The rating measured how deeply a person could retreat from the world — and therefore how easily they could be extracted from it.
"They're a predator," Isha said, the word tasting like metal in her mouth. "A specific kind. Not opportunistic — strategic. They study their targets. They wait for the right moment. They rate them on a scale that measures how easily they can be taken. And then they take them."
"Take them where?"
"That's the question that matters."
Raghav's phone buzzed. He read the message, and his face did something Isha had learned to recognise from years of watching people receive bad news: a momentary blankness, the face resetting before the emotion arrives.
"Subject #028," he said. "Vikram Singh. The fitness trainer from Dwarka."
"What about him?"
"They found him."
"Alive?"
