Lenny Thornber is a malicious juvenile delinquent and thief holding a small village in fear of reporting him. After Maureen O'Callaghan courageously makes an official complaint against him, he sets fire to her car in revenge. DCI Adams recruits Hetty to investigate. With Geoffrey posing as her son, she poses as Maureen's sister-in-law from Ireland in order to move around freely and gather evidence against him and his associates.
