A goodish book.
In this book we follow Jamie Blair and his life in Walworth. How he inveigles himself into the household, finding himself responsible for the step children of the man of the house, after he dies. The police think it suspicious and act accordingly. We have the awful step father's sister just as bad, and she gets her own come uppance.
Not for me as good as the Adams family books but good enough. Nothing bad about it. Usual humour that you find in her books.
