In 1989 ITV broadcast a feature-length pilot, "Missing Persons", featuring Tony Melody as Robert Wainthropp and Garry Halliday as Geoffrey Shawcross, but ITV opted not to pursue a series. The storyline of this episode is ignored in the subsequent BBC series, with the first episode establishing Hetty as a detective in her first case and meeting Geoffrey for the first time. The characterization of Hetty was altered considerably for the series from the pilot. The 'original' Hetty was blonde and far more 'theatrical' in her manner. Additionally, the pilot character lived in considerably better circumstances than the home seen in the series.
