Instead of spending her golden years lying down, the indomitable Hetty Wainthropp found her calling late in life. Combining common sense, her husband, and her pocketbook, this senior sleuth takes on all the cases the police deem too minor.
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.
Robert goes undercover to help Hetty solve a case of stolen property involving a suspicious drowning. Posing as a wheelchair-bound millionaire, with Geoffrey along for the ride as his chauffeur, he finds himself at the scene of the "accident" in the company of a questionable character.
A reclusive senior is holding up a real estate deal by refusing to leave her condemned apartment building. Hetty is offered a fabulous bribe when she discovers something suspicious about the structure.
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.
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.
Robert's brother Frank comes to stay, and brings Hetty the case of a missing Victorian school ma'am.
