1914: Lady Beaufort already has three boys and she certainly doesn’t want another child. But her husband Aubrey has always dreamed of a daughter to fill the gap his sister left when she died tragically young.

Their children Victoria and Leila meet when Lady Beaufort sends Victoria to the village school out of spite, jealous of her captivating daughter. Victoria’s parents adore their only child Leila, though they are surprised she does not excel academically as her father did. Though Harold is an impoverished teacher, whose family have a meagre existence, he was a talented Oxford scholar. Despite the differences in their backgrounds, the two girls share a special friendship as well as a birthday; but before long both families start to fear something is wrong . . .
