Murder in Mont Saint-Michel

"Situated off the Normandy coast, Mont-Saint Michel has been many things in its history: a prison, a siege fortress and an abbey. When Maggie and Laurent--who are struggling with the revelation of a family secret that threatens their marriage--take part in a couples' counseling weekend on the island they are thrust head first into the setting for a brutal double murder. Because a once-in-a-century storm is bearing down on the island preventing communication with the outside world, their small group of six is trapped on the island--with a murderer. And the clock is ticking. Maggie has only one night to find the killer--and elicit a confession--before the police arrive and go with the obvious evidence--all of which points directly at Laurent."--Amazon.com
