And in the cover image, is my wife's ancestor Thomas Henry Nairne, from the tiny town of Borambil, New South Wales. Killed in action in 1917, he has no known grave and is commemorated on the Menin Gate.
This photo was found in the shed of a relative. Note Stonehenge in the bottom corner, indicating this image was taken in Salisbury, during training. These are the details you need to spot to decipher the clues.
