Mysteries of Jalna

We were talking about bookshelf staples, the sort that nobody talks much about these days but that are still to be found on the shelves of public libraries, at least in large-type editions for elderly readers. I thought I remembered that Mazo de la Roche was Canadian, but until now I never knew that the writer was a woman. CCH used to laugh at the Jalna books, but there was at least one on the shelves at LP, so somebody had read them sometime.
