Emily Lane is a friendly woman who owns a charming year-round Christmas-themed store called Under the Mistletoe in the quaint tourist town of Fletcher's Grove. While she is outwardly optimistic, her inner voice reveals a sardonic sense of humor, cunning intellect, and an eye for detail... because Emily has a big secret.

Emily finds herself compelled to investigate local murders. When she begins her personal investigations, Detective Sam Wilner, a smart local cop with a crush on Emily, begins to wonder if there is more to Emily than meets the eye.
