Luck found Joseph in the shape of a letter. It was delivered by a young schoolteacher named Riya who had noticed the photograph peeking out of his shirt when she bought a packet of biscuits. The letter had smudged ink on it, old and official, and Riya’s eyes widened when Joseph opened it. Inside was a name—one that matched the boy in the photograph—and an address pinned in a city many miles away. A hospital had been keeping records of children reunited with families—records Joseph had avoided for years because the past, once opened, yawned into complicated rooms.
