Bugging in Six Easy Lessons

Chris Serle sets out to investigate the bugging game. In a top-floor office of a skyscraper two men are having a secret conversation. From the skyscraper across the street a snooper directs a special laser on to the office window, picking up the tiny movements in the glass every time one of them speaks. Futuristic equipment turns these movements into minute electric signals. Eventually it is decoded back into sound. Fact or fantasy? Don't ask the people in the bugging business. They've become so confused between real life and Hollywood they no longer know which is which.
