Suzie and Mary are enjoying running Dune House, the majestic Bed and Breakfast on the beach. They are happy with their lives in the small seaside town of Garber, but they are looking for something to spice things up a bit.

They get exactly that, but in the most unexpected and unwelcome way, when a guest dies on the premises. Although the police believe it is an accident, the friends believe that it is murder. They do whatever they can to uncover the truth and protect the reputation of Dune House. Even when it means putting their own lives at risk.

Will they be able to catch the killer? Or was the death really accidental?
