Dick and the Duchess (1957)

Dick and the Duchess is a rare 1950s CBS situation comedy shot and set in London; it was one of the earliest of filmed television series in the UK. A multinational insurance company stationed American Dick Starrett in London as an investigator and adjuster. His wife, Jane, daughter of an English earl, and her family were less than enchanted with her marriage to a commoner — and an American at that. Jane feels that she had been 'Americanised' by movie and television crime stories enough to be a detective, so she often tries to help with Dick's investigations, although she usually causes more problems by doing so.
