It’s winter in Bordeaux, and Philip and Genevieve Warwick—better known now as Lord and Lady Crosswick—are hosting a holiday wedding at their picture-perfect vineyard, Château Beaulieu.

But in the midst of the festivities, the Warwicks’ impeccably proper butler discovers a chilling note vowing vengeance on their family. Soon, a succession of increasingly sinister events threatens the celebration: a suspicious heart attack, a stolen horse, a sighting of an ancestral ghost, a vanished family jewel—and a missing child.

Then vicious rumors begin spreading on the dark web, designed to destroy the reputation and legacy of this generational family. Someone is determined to tear down everything the House of Crosswick has built, and the attacks are becoming dangerously personal.

With their signature humor, daring, and appetite for adventure, Philip and Genevieve fight back. But to protect their chronically endangered family and friends, the amateur sleuths must uncover who is behind the campaign against them—and settle an old score before Christmas at the château ends in tragedy.

Vengeance at the Vineyard is a lively holiday whodunit filled with family secrets, festive intrigue, and a final twist you won’t see coming.
