“It took three. The police Bolero appeared on Main Road with the quiet authority of a vehicle that did not need a siren because the town was small enough for the engine alone to constitute an announcement. Vikrant parked behind the Dzire. He got out. He walked to the driver's window with the specific, measured walk of a man who had been trained to approach vehicles and who understood that the walk was the first communication — the pace, the posture, the deliberate visibility of the uniform and the stars and the authority they represented.”
