Recently retired English professor Harriet `Harry' Wild discovers a knack for investigation and is compelled to intervene in cases assigned to her police detective son.
Due to their new notoriety, a woman approaches Harry and Fergus in desperation to find out how her husband died. Although reluctant to get involved, Harry's interest is soon piqued.
Harry enlists her granddaughter Lola to go undercover at a girls' school in pursuit of a bank robber who committed murder to fake his own death.
Harry and Fergus agree to help Happy, a local loan shark, find out who murdered his employee. In return, Happy will cancel the sizeable debt Fergus's father owes.
A stuffy dinner party in the home of Harry's former colleague goes awry when a vomiting bug hits all the guests but Harry. After the cause of the sickness is traced to a dead body in the home's well, Vicky Boyle leads the investigation.
A violent storm traps Harry, Fergus and Lola in the local pub. Cut off from the outside world, the trio are put in even more peril when they discover a kidnap victim in a car.
