December 1882

When cook Kat Holloway is blamed when a dinner guest mysteriously takes ill after eating one of her meals, she sets out to prove she had nothing to do with the gentleman's sickness. She discovers a whole host of people who might wish to do away with the man, and she and her friends—Daniel McAdam, Lady Cynthia, Mr. Thanos, and various members of the household staff—begin to hunt for the would-be killer.

Simultaneously tasked with crafting the perfect Christmas feast, including the pièce de résistance, the Christmas plum pudding, Kat frantically works to finish all, fearing she'll have to choose between stopping a murderer and cherishing her few precious Christmas moments with her daughter.
