Hetty Wainthropp Investigates is based on characters from the novel
Missing Persons (1986) by
David Cook, who co-wrote the episodes with
John Bowen. The incidents in Cook's novel were inspired by his own mother's experiences. Prior to the pilot going into production, Patricia Routledge read the story
Missing Persons for BBC Radio 4's
A Book At Bedtime in February 1987. In
1990 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 characterisation 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. The BBC series was filmed primarily in
Burnley,
Darwen,
Blackburn,
Rossendale,
Bolton and other locations in
Lancashire. The music for the series was composed by
Nigel Hess, the cornet solo was performed by Phillip McCann and in 1997 the title track was awarded the
Ivor Novello Award for best television theme. The BBC series was popular with viewers, but no further episodes were commissioned after 1998. In 2008 Patricia Routledge said in an interview that the cast and crew had been told by the BBC at the end of the fourth series that a fifth series would be commissioned, but it never was. In 2017
Suzanne Maddock shared her memories of making
Hetty Wainthropp Investigates in a 45-minute interview for "The Bill Podcast" and explained how she felt disappointed for the fans of the series that they did not get to see a proper conclusion to the series. ==Synopsis==
