Something old, something new, something borrowed and someone's blue...

Finally feeling like Sea Isle, Scotland is becoming her new home, American doctor Emilia McRoy is delighted when she is invited to a wedding at Morrigan's Castle. Her friends have warned her that it's a three-day party and it's bound to get wild, not to mention the impending snowstorm. Constable Ewan Campbell, owner of the castle, ensures their safety with the blizzard. What he didn't ensure, is that all of his guests would survive the night alive. When Emilia explores the impressive castle, she finds a dead man in one of the turrets.

The snowstorm hits and the local police can't reach the castle until it lets up. With no one able to leave, the family insists they carry on with the wedding, which makes Emilia's job as the coroner a bit easier--the suspects are in one place­--and complicated because the killer has Emilia in his sights. The fact no one claims to know the victim isn't helping. Why would someone no one knows be murdered at a castle in the middle of nowhere?

It's up to Emilia to uncover the mystery who the victim is, so the killer doesn't get away Scot free.
