Hoping to dispel the late-winter gloom, innkeeper Judith McMonigle Flynn flies off for a much-needed vacation to Scotland. But soon she and prickly Cousin Renie find themselves marooned in an ancient castle perched high above the North Sea while their husbands go off on a fishing trip with the local police inspector. But when an explosion rocks Grimlock Castle, leaving a dead body in its fiery wake, an ever-curious Judith is once again up to her neck in a murder investigation. And the situation grows even murkier when the husbands and their Scotland Yard buddy go missing . . .
The hunt is on for a killer through the bonnie braes and sea-green glens of Scotland. And if Judith and Renie aren't careful, this could turn out to be their most dangerous--and last--Highland fling.
