“I never knew what an extraordinary thing it could be to write a book. In the first place, the characters take the bit between their jaws and canter off with you into places you don’t want and never catered for. I had smugly intended my book to be about a family rather like ours, but, lud love you! it’s already turned into an account of a barmaid’s career in an Edgware Road pub, and I can’t squeeze us in anywhere!
