Mallory Ryan is a police constable working in Perth, Australia.
Mallory grew up on a ranch in Bindoon, Australia, where she started a relationship with George "Digger" Harkness when they were teens. Her father disapproved, and she didn't like several things about him, but was drawn to him all the same. She later moved to Perth, and after her father died, became a police constable. She was reunited with Digger while on the job, as she was on the scene of one of his robberies. She told him to stop, but he cut her arm with a boomerang before she could react. He escaped.
