A Sound Revolution. The true story of Marie Louise Killick's valiant fight against powerful men in the musical world. They had pirated her invention of a stylus that was to revolutionize the quality of sound reproduction of gramophone records. Despite winning her 10 year legal battle in The Royal Courts of Justice in London, England, her opponents, Pye Radio, found other means to ensure she never received her damages - worth millions. Manoeuvred into bankruptcy, she spent three years trying to prevent the Official Receiver from settling her damage claim against Pye Radio for a derisory sum. She died at the age of 49, penniless and homeless. During her fight she was 'kidnapped', her supporters were assaulted and even her solicitor was frightened off the case. During the fight, she was hounded from pillar to post and forced to spend six weeks with her children living in a builder's yard. Truly a story of enormous courage and tenacity on her part to bring the men who had robbed her to justice!
