Take a Look at the Five and Ten

This is very much a Connie Willis holiday story, with the usual elements of her stories: comedic mixed messages leading to misunderstandings, a mildly-malicious antagonist, a bit of a mystery which gets solved, and a happy ending. This is the sort of thing you will enjoy if you enjoy this sort of thing. If you're not a Willis fan, this won't change your mind, but if you need something cheerful and uplifting, this may be just the ticket.
