Needing to escape from it all, Gemma agrees to help renovate a rundown farmhouse in Doullens, France, a town near the Somme. There, in a boarded-up cupboard, wrapped in old newspapers, is a tin that reveals the secret letters and heartache of Alice Le Breton, a young volunteer nurse who worked in a casualty clearing station near the front line.
