When we first met Paula Spencer - in "The Woman Who Walked into Doors" - she was thirty-nine, recently widowed, an alcoholic struggling to hold her family together. Paula Spencer begins on the eve of Paula's forty-eighth birthday. She hasn't had a drink for four months and five days. Her youngest children, Jack and Leanne, are still living with her. They're grand kids, but she worries about Leanne. Paula still works as a cleaner, but all the others doing the job now seem to come from Eastern Europe, and the checkout girls in the supermarket are Nigerian. You can get a cappuccino in the cafe, and her sister Carmel is thinking of buying a holiday home in Bulgaria.
