Constable Stubblefield is the policewoman in Famous 5: On the Case. She is reliable when it comes to arresting the villains after the kids foil their plots. However, she is more interested in reading romance novels than stopping crime. She is revealed to be a big fan of her favorite romance writer, Fantastico. Constable Stubblefield refers to the group as "Kirrins", since they are staying at George Kirrin's house and are part of the Kirrin family.
