Nicholas Lampoon quits his job as a detective in the city to join his sister Penny in the suburbs for a "boring life" in the tea business. However, things take a turn as the new Yellow Petal Tea House manager begins to uncover the murder of a poor banker buried in the graveyard across the street only days before Nicholas quit. With much force, Penny and his house keeper Ms. Applebury convince him to get involved in the confusing case of the banker's widow and many others along the way.
