Johnny, an outstanding young swimmer, went missing nearly thirty years ago: drowned, or so everyone except his sister Imogen believes. How could this have happened? Encouraged, pushed even, from a child by his father, Johnny could have made the Olympic team, couldn't he? As Imogen gradually pieces together bits of her family history, we hear the tragic echoes that connect her with the Great War and Ireland in the nineteen-twenties.
