Murder on the Precipice takes place on the rocky coast of Maine in an old family-run inn where a young female guest goes missing in a case eerily similar to an unsolved disappearance years earlier when the property was used as an all-girls school. Elizabeth Pennington, a successful Manhattan interior designer, grew up in the inn and is thrilled to leave behind her hectic job and her tyrannical boss to help her grandmother who still runs the inn. Elizabeth makes it her mission to find the girl . . . before a murderer in their midst strikes again.
