An amateur sleuth with a bed and breakfast, an unfriendly resident found dead, and a handsome detective who helps unravel the mystery in the cozy beach town of Sweetfern Harbor.

Brenda Sheffield can't believe her luck when she finds out that the family business, The Sheffield Bed and Breakfast, has been handed down to her upon the death of a relative. For too long, she's been idle as an assistant to a PI - a new challenge is precisely what she needs.

Uprooting to the idyllic village of Sweetfern Harbor was tough, but it doesn't take long for Brenda to fall for the brightly painted shopfronts and the friendly residents. However, there's always one who spoils the bouquet. Lady Pendleton owns half of the buildings in Sweetfern Harbor, and she rules with a green-fingered fist. With a personal vendetta against everyone, she ruthlessly raises rent and rates - resulting in turning many people out of house, home, and business.

One day, her flashy car pulls up outside The Sheffield Bed and Breakfast, but Brenda is shocked to find her slumped over the wheel and failing to respond. The coroner pronounces her dead at the scene, ruling it as a homicide.

With the entire town a suspect, Brenda isn't sure whom to turn to since crime isn't usually a factor in this New England town. Enter the handsome Detective Mac Rivers, who must unravel the twists and turns of this murder - but can an outsider's sleuthing experience help bring the perpetrator to justice? Or will they slip out of sight unnoticed - or strike down another victim?
