Recently engaged Jane Wunderly is celebrating Christmas with her fiancé at his ancestral home at the quaint English market town of Barnard Castle—where murder is the new family tradition …

Northern England, 1926: Surprised by her eager acceptance of Redvers’ proposal, Jane is ready to spend the festive season deciphering the mysterious man she agreed to marry, while surviving scrutiny from the icy Dibble clan at their snow dusted manor. But all attention shifts to the announcement of upcoming nuptials between the humorless Evelyn Hesse and the man who will become Jane’s father-in-law.

One fact is clear—Evelyn shouldn’t be trusted. Not as rumors swirl about the deaths of her other husbands. Not after a man is murdered at a party before Christmas Day. With one wedding approaching and their own in peril, Jane and Redvers must dash to unravel dark secrets that could ruin their first holiday together … or cost another person their life.
