The stories follow teenage detective Nancy Drew. Her father, Carson Drew, is a successful attorney and a widower. Their house is taken care of by their full-time housekeeper, Hannah Gruen.

They break-up and reconcile multiple times throughout the series. But in the last book of this series, it is shown that they kept dating each other.
