September 1919: 20 year-old Tristan Sadler takes a train from London to Norwich to deliver a clutch of letters to Marian Bancroft. Tristan fought alongside Marian's brother Will during the Great War. They trained together. They fought together. But in 1917, Will laid down his guns on the battlefield, declared himself a conscientious objector and was shot as a traitor, an act which has brought shame and dishonour on the Bancroft family. The letters however are not the real reason for Tristan's visit. He holds a secret deep within him. One that he is desperate to unburden himself of to Marian, if he can only find the courage. Whatever happens, this meeting will change his life - forever.
