I did manage to whittle my selection down to two books to bring home with me:
Miss Pettigrew Lives For A Day by Winifred Watson and Good Evening, Mrs Craven: The Wartime Stories of Mollie Panter-Downes.
I chose Miss Pettigrew because I have seen, and loved, the movie with Frances McDormand and Amy Adams and I have read some other bloggers talking positively about Mollie Panter-Downes. It was so hard to only walk out of that shop with two books though!! I'm going to be putting in a mail order very soon I think - can you let me know what Persephone books I should collect next? What is your favourite?
