A Christmas Guest

Mariah Ellison isn't merely disappointed to learn that she won't spend Christmas at home with her married granddaughter: she is furious. Instead, Grandmama is being packed off to stay with the ex-daughter-in-law with whom she has never got on well. There will be nothing to do, no one to visit, and no doubt the terrible weather will make even taking a walk impossible. It is going to be the worst Christmas of her life. Then something shocking and quite unexpected happens. Has a crime been committed? Grandmama is surprised to find herself turning detective - and proving extremely good at it.
