Mrs. Jeffries and the mistletoe mix-up

Under a bundle of mistletoe, art collector Daniel McCourt lies with his throat slit, a bloody sword next to his body. Inspector Witherspoon is determined to solve the case--preferably before the eggnog is ladled out on Christmas Eve--but of course he will require assistance from the always sharp-witted housekeeper, Mrs. Jeffries, who has a few of her own theories on why McCourt had to die by the sword.
