Aanya is 6. Riya looks away for 30 seconds. Aanya is gone.
The food court is packed. Riya runs to the help desk. The guard, Suresh, asks if Aanya is wearing anything with a number on it. Riya shows him the pink silicone wristband from QRSprint, scanned three months ago, half-forgotten.
Three minutes later, security spots Aanya at the Hamleys window. The guard scans the wristband with his phone camera. He sees Riya's first name, a green WhatsApp button, the line 'allergic to peanuts, asthma inhaler in mom's bag'. He taps message.
Riya's phone buzzes. The number on screen is +91 93729 55150, QRSprint Relay. The message: a stranger she will never need to thank by name, telling her where her daughter is.
