A friend of mine was in the UK a few weeks ago.
He was in a second hand bookshop and was kind enough to buy a book he knew would interest me.
The World Of Upstairs Downstairs by Mollie Hardwick.
It's a large richly illustrated social history of the years covered in the series.
At times we view the period as seen through various charactors from the series!.
Sounds a bit dodgy but it works.A bit like reading their thoughts.
Am really enjoying it.
