In the late 1980s, when I was 18, I lodged with a retired couple in the sleepy town of Budleigh Salterton. Their accommodation was in the upstairs flat of a grand old Victorian house in extensive grounds near where I worked. Mr W was a retired police chief and his wife had been, for much of her working life, a matron at a girls public school They had two children, a girl and a boy, slightly older than me who lived in London. They were both tall, elegantly dressed people and well spoken. Mrs W had shoulder length black hair
