On a dark midwinter's night in an ancient inn on the river Thames, an extraordinary event takes place. Suddenly, the door bursts open on a grievously wounded stranger. In his arms is the lifeless body of a small child. Hours later, the girl stirs, takes a breath and returns to life. Is it a miracle? Is it magic? Or can science provide an explanation? Those who dwell on the riverbank apply all their ingenuity to solving the puzzle of the girl who died and lived again, yet as the days pass the mystery only deepens. The child herself is mute and unable to answer the essential questions: Who is she? Where did she come from? And to whom does she belong?
