Lexy Campbell is long overdue a trip to Scotland to see her parents, and an unexpected death in the extended Last Ditch Motel family makes Christmas in a bungalow in Dundee with nine others seem almost irresistible. But when Lexy and the Last Ditch crew hop across the Atlantic, there's a change of plan and they're whisked off to Mistletoe Hall in the pretty village of Yule, where the surprises continue. The news that a man disappeared from the crumbling pile sixty years ago, along with an unsettling discovery in the bricked-up basement, means that Todd, Kathi and Lexy - Trinity for Trouble - must solve another murder.
