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.

During a quiet hospital stay for surgery, Hetty uncovers a robbery ring run by nurses and helps clear D.C.I. Adams in a sexual assault frame-up. Meanwhile, Hetty's brother-in-law, Frank, gets mixed up with a lusty widow.

Hetty is approached by Hansi, a German gentleman whose golden years have been hampered by a painstaking search for his sister, whom he lost contact with during World War II.

However, Hetty passes the case off to Geoffrey and Janet, when it comes to light that this is not the only pain Hansi has been suffering. Someone at his retirement community has been making pointed references to Nazism at Hansi, something he had never been a part of. The person is going so far as to deface Hansi's garden in the shape of a Swastika.

Hetty goes undercover as a potential tenant of the retirement community, where she comes into contact with characters that seem to come right out of the mystery novel she's reading: a regimental romantic, a frail woman who has remained alone since her fiance's death in the war, among others. All seem to have motives for harming Hansi.

Geoffrey and Janet find Hansi's nephew, only to find that he is ashamed of his uncle's German heritage and prefers to continue hiding.

Missing gems and precious metals drive a mining community to madness as Hetty searches for buried treasure stashed by a miner killed in a cave-in. Hot on the trail of the lost loot, Geoffrey, too, is caught in an underground accident.

Hetty goes to visit a long lost cousin in a small fishing village near Whitby. She soon finds a client - an elderly lady who is being troubled by mysterious sounds of a dog barking. Meanwhile back home Robert plans an exposé on a local building firm - but are his facts correct - and Janet is having problems with an obnoxious neighbour who won't take no for an answer.
