This is exactly the kind of murder I'm in the mood for. More stories about women upwards of "a certain age" who can get away with murder. That's much more fun than solving one.
I've been a fan of the Christmas murder story nearly as long as I can remember: there was a tiny book of four short stories put out by Reader's Digest in the early 70s. It had a white cover and four images in black one of which was a bishop and another was a sprig of holly. One story was about a man who had planned the perfect crime to murder his wife before taking a sabbatical in the US for a year. One was a locked room mystery about a chess player. Well, that's what memory says and it is of course always so precisely accurate.
Only one of these stories is about Christmas, "An Elderly Lady Seeks Peace at Christmastime" as do we all. But they all share a calm, quiet, unhurried feel. Maud isn't a stereotypical granny. Now, having just learned that there is a book about Audrey Hepburn in wartime as a member of the resistance, I have a strong longing to read about Maud as a college student during the war.
Library copy, but something I'd like to own and revisit annually.
