I hoped your mum enjoyed the book Brenda
I saw the new Judi Dench film today, Philomena (On at Canterbury Odeon) which has a similar theme. I had no idea what it was about before I went. I just went to the pictures to kill time between a bank appointment and a hospital appointment - BUT, it was an excellent film. Again, not really Newham, but gives an idea of how badly treated pregnant girls were by the church and their families.
I can't recommend this film highly enough - it really does have you laughing one minute and have 'smoke in your eyes' the next.
