When I re-read the book i found I wanted more about Midge and Lydia. Midge was much nastier in the book than she appeared on television. Axtell, the Communist, has TB in the book and there is no relationship but friendship between him and Sarah, so that was all made up.
I thought Mrs Beddows was the most accurately reproduced character (Penelope Wilton very good, even if she didn't look seventy two) and I think the jealousy between her and Sarah over Carne did come out. Her telling Sarah what's what at the end was very like the book although the railway scene was just put in for dramatic effect. My problem with both the book and the TV version is that I just can't see the attraction of Carne.
