A new walking tour celebrating a quirky detective show has had interest "from all over the country", its organiser says.
John Hughes, who has run the "Haunted and Hidden Bristol" tour for more than 20 years, has now launched a route based on the locations used to film the BBC TV show Shoestring, starring Trevor Eve.
Shoestring ran for two seasons on the BBC in 1979 and 1980 and attracted up to 20 million viewers an episode.
Mr Hughes said there is still a lot of nostalgia about the show because "it shows Bristol as it used to be" and lots of the filming locations are still unchanged after 40 years.
