Malcolm has held on to a secret for more than fifty years: a letter his sister Sophy gave him just before she died. He had promised to give it to the young doctor she met one night during the Liverpool Blitz: a night that altered the course of her life. But the letter was never delivered. Now, after so many years of uncertainty, Malcolm has decided to share Sophy’s secret with her daughter Agnes. It is the day of Agnes’s daughter’s wedding party. The ghosts of Agnes’s past and all the powerful emotions of the family reunion wrap around her thoughts. Until she is distracted by a hand on her arm as her uncle Malcolm holds out an envelope for her to take.
