Late in 2018, I had a message from a stranger in the United States. He was delighted, he said, to see Bernard Leach’s A Potter’s Book included in my list of six favourites in a magazine he had been reading. He was a potter, his name was Jeff Diehl, and he thought the Leach classic was an unusual title to feature on a novelist’s list. I wrote back explaining that though my work was writing and designing book jackets, I made pots too (after a fashion). Over the next months this kind stranger replied in careful detail to every question I asked him about kilns, glazes, pots, wheels. He sent me formulae for glazes he thought might work for me; he worked out programmes suited to my new kiln, sent video links, articles. The generosity was staggering. There also came fragments about Lockbridge Pottery, and his family and other animals: his potter-wife Donna, their two sons, their dog and cat. Our messages travelled on the internet, but they felt like letters....
