As Shaw tells his story his second daughter, Penny, aged 14, arrives in the kitchen with a drawing. It is a childish map of the farmhouse garden where she has pencilled in her plans to grow peas, potatoes and beans to sell to make some money. A third daughter, Harriet, 12, tucks into some sandwiches before starting her holiday job collecting eggs. And there is now a fourth mouth to feed. Mr Shaw had an affair three years ago with a girl called Sue. The result was a baby, Isabella, aged two and a half, who lives with her mother in Cheshire.
