Dick Barton - Special Agent was a BBC radio drama that aired from 1946 to 1951. The series followed the adventures of ex-Commando Captain Richard Barton MC who, along with his teammates Jock Anderson and Snowy White solved crimes and saved the nation from disaster.
In 1972, the BBC broadcast a new, abridged, 10-episode version of the very first Barton serial “The Secret Weapon”, starring many members of the original cast. This audio drama series is hosted on the Internet Archive.
