Called to investigate a string of robberies targeting Indian restaurant owners, Hetty herself is mugged! The plot thickens when Robert is the unwitting receiver of stolen goods. As Hetty delves deeper into the activities of the masked bandits, Geoffrey, sporting a stunning new hair-do, rides shotgun for her protection.

Hetty sends Geoffrey undercover when it comes to light that the owner of a local gym and fitness centre may be supplying people with dangerous anabolic steroids.

Robert's brother Frank comes to stay, and brings Hetty the case of a missing Victorian school ma'am.
