In ‘Wounded: a Great War novel’ I allude to how ill at ease Snow seemed at family gatherings, especially weddings and christenings – strangely withdrawn. I think this photograph of my mother and father taken with the author on the day of his christening tells you where that idea came from.

Found this pocket map of the French and Belgium battle lines in Dad’s cedar box of ‘old war secrets’. The pencil sketch, annotated ‘fire bay’, is particularly evocative. The hand-writing is unclear but seems to indicate details of a transfer from one battalion, possibly 34th, to another, in May and June 1917 (author unknown).
