Well, she doesn't write now coz she's RIP but back in the day she wrote good stories just about ordinary peeps...minutae of London life mainly. I like kitchen-sink type stuff a lot of the time. Some of her best books are sortov autobiographical from when she was a nurse and especially when she worked below stairs back in the 1930s...with her coming from an upper class type family (she was presented at court as a deb) she did have to hide some of the time coz the guests were peeps known to her.
