The point is made clear in this blog. I recently started Life Class by Pat Barker, having previously read Toby's Room. The background to the fictional story is based on a real group of friends who went to Slade School of Art, one of whom was Vernon Ward who painted the picture of Mousehole above. A print which holds a fascination for me.
One of the students at the time in question was Ben Nicholson, who a few years later moved to Cornwall and formed the St. Ives School of Art. St. Ives is not far from Mousehole, and I have a friend who lives not far from the area too.
Ms. Barker was born in Thornaby-on-Tess, not 10 miles from where I was born. Her books tell of the struggle of men returning to life after WW1, and the beginning of modern plastic surgery. My WW1 ghost story https://www.draft2digital.com/book/32122 tells of the social impact the war forced on people.
