"Always trust a stranger," said David’s mother when he returned from Rome. "It’s the people you know who let you down."

Half a life later, David is Father Anderton, a Catholic priest with a small parish in Scotland. He befriends two local teenagers who live in a world he barely understands. Their company stirs memories of earlier happiness—his days at a Catholic school in Yorkshire, the student revolt in 1960s Oxford, and a choice he once made in the orange groves of Rome. But their friendship also ignites the suspicions and smoldering hatred of a town that resents strangers, and brings Father David to a reckoning with the gathered tensions of past and present.
