 In the early episodes Frazer kept a philately shop but, by series four, the writers had decided that he should become the local undertaker, in keeping with his gloomy nature.Openly eager for more power within the platoon, he sometimes led rebellions against Mainwaring; in response Mainwaring temporarily let Frazer take over as captain in "If the Cap Fits...".Frazer was the only member of the platoon to be portrayed as a villain in episodes such as "A Soldier's Farewell" and "The Two and a Half Feathers", though for the most part he was loyal and well-intentioned.
