A crossword clue sends Sheila back to a train journey from Norwich. She had packed a sandwich, a book and a timetable, then spent the trip watching the changing sky. At the coast, she bought a postcard of the view directly in front of her. It seemed inefficient, which pleased her. Now the card marks her place in a music book beside the hospital bed. The crossword answer is obvious once she stops trying to make it clever. She writes it in, then checks the crossing letters anyway.
