Janet,
The novel "Mapp and Lucia" was made into a television series several years ago... which might be how you heard of it. I was lucky enough to have seen it when it aired on television, and I loved it so much that I then bought the series of books. The television series was made in the UK, and stars Geraldine McEwan, Prunella Scales, and Nigel Hawthorne. It is a wonderfully cast series, and it does justice to the novel. The only bad thing about the television series is that they didn't make all of the novels into shows. I cannot recommend E. F. Benson enough!
