An agency with a promise to keep.
The premise is a detective business rather than a police station. Assignments Unlimited operates from the address in the title, and Aubrey Mason is the investigator expected to make its ambitious promise work. Clients bring the problem; Mason has to discover what accepting it will involve.
The London setting can obscure the programme's origins. This is a South African production associated with Springbok Radio, not a British network drama simply because its characters work in London.

South African radio, a London address.
The Encyclopaedia of South African Theatre, Film, Media and Performance dates the 58-episode series to 1965-1966 on Springbok Radio, part of the SABC. It names Adrian Steed as the original writer, followed by Douglas Laws.
The 45 recordings available here are the Heritage Radio Vault selection. That listening-library count does not imply that the original programme produced only 45 episodes.
Did you know?
The university reference distinguishes this radio detective series from The Man in Half Moon Street and the later film Half Moon Street. A similar address does not make those films adaptations of Aubrey Mason's cases.
