Springbok Radio of South Africa produced many original radio shows including Walk Softly Peter Troy. Peter Troy was a show modeled after all of the hard-boiled, noir type detective shows. Set in London, the show featured fast women and lots of action. Keeping with the detective tradition, there was also the friend/enemy detective. The show starred Tom Meehan, John Simpson, and Merle Wayne.
Many radio shows feature an interesting way to name their shows. Some shows have titles with colors in them or they have titles with a particular phrase. The Peter Troy shows all featured titles related to women like vixen, doll and witch.
The show was on the air from December 1963 until February 1964 on Springbok, then moved to the English Service from May to November 1964. Apparently, the sponsor on Springbok, Irving and Johnson, did not like the show so they withdrew their sponsorship.
