Nine-year-old Lawrence is the man in his family. He carefully watches over his willful little sister, Jemima, and his mother, Hannah. When Hannah becomes convinced that their estranged father is stalking them, the family flees London and heads for Rome, where Hannah lived happily as a young woman. For Lawrence, fascinated by stories of popes and emperors, Rome is an adventure. Though they are short of money, and move from home to home, staying with his mother’s old friends, little by little their new life seems to be taking shape. But the trouble that brought them to Italy will not quite leave them in peace.
