In this episode themes of morality are raised when after Fernadez is murdered Jeff tips off a newspaper contact named Barry Jones who pays him well for story information. Jeannie on the other hand shows some moral compunction by questioning Jeff's ethics in selling a story. "Well, did you get your blood money?" she demands of Jeff.
We also learn that Jeff once paid Jeannie with a gold earring "in lieu of salary" again revealing his financial difficulties.
Jeff is hit many times in this episode. He is coshed over the head, shot at four times, nearly hit with a large sandbag and a thrown revolver, and worst of all is knocked out by a shelf tipped on him in the basement as he is searching for clues.
Meanwhile in this episode Marty acquires a taste for dining at the finest restaurants, remarking that he had recently dined at the Savoy with Harold Wilson.
