Dear Mr Cornwell, I once wrote to you asking permission to feature “Sharpe’s Escape” on the “Shelf Improvement” page of a magazine I used to publish, which you kindly agreed to. My next request is not so straightforward. A good friend of mine, who first introduced me to your work, is more than a little keen on body art and is looking for any illustrations of Derfel from the Arthur trilogy. He is intending to place him (appropriately) on his left forearm and requires some inspiration for the tattooist. Can you help? May your inkwell never run dry! Stuart Tristram
