Lady Kiera Darby and her husband Sebastian Gage are looking forward to celebrating with new friends at an exciting yearly soiree, but they soon learn that murder never takes a holiday.
January 1832. After enjoying a delightful few weeks with her family, expectant mother Kiera and Sebastian Gage have been invited to the Duchess of Bowmont's Twelfth Night party in Traquair, Scotland. Though she normally avoids such fashionable, rambunctious events, Kiera is ready to join in the festive merrymaking. But upon their arrival at the opulent estate, it becomes obvious that all is not merry in their hostess's home. The family appears to be under a great strain, and someone seems determined to cause mayhem among the guests with a series of forged notes.
Matters swiftly turn from irksome to downright deadly when the partygoers stumble upon a decomposing body in the castle's crypt. The corpse is thought to be the duchess's son-in-law who had purportedly traveled to Paris more than a month earlier. It is evident the man met with foul play, and Kiera and Gage soon realize that a ruthless murderer walks among them—and may well be a member of the duchess's own family. And when the investigation takes a treacherous turn, Kiera discovers just how deep the killer is willing to dig to keep their secrets from ever seeing the light of day.
