Strange things start happening around her home at Christmastime and her late husband's family arrive to spend the holidays with their own baggage weighing heavy. But house guests are only the start of Imogen's trouble: nightmarish visitors, misplaced books, anonymous letters, a stolen cat... oh, and accusations of murder - what holiday would be complete without them! So, stoke the fire and grab your favourite grog, it's time for a holiday mystery!
