Richard Jeperson is a fictional character created by British horror / fantasy author Kim Newman.
As such, he shares many character traits with them – a flamboyant dress sense, upper-class tastes and sensibilities combined with a youthful appreciation of the 'trendy' aspects of 1970s culture, a chivalrous and patriotic nature, and a healthy disdain for most representations of establishment authority.
The stories in which he appears also parody / homage these telefantasy shows, and frequently examine 1970s British culture and society through this lens.
In these stories, the character acts as an investigator for the Diogenes Club (established in the Sherlock Holmes stories by Arthur Conan Doyle), a branch of Britain's intelligence and law-enforcement community existing outside of regular channels designed to investigate (and where necessary, put a stop to) psychic, paranormal and unusual phenomena.
The character himself is unusually empathic to an explicitly paranormal level, possessing a keen sensitivity to both these phenomena and to the thoughts and feelings of others.
