The summer of 1982 was long-seared into the Irish public imagination for more than just record temperatures. That July, aristocrat Malcolm Macarthur went on a killing spree, taking the lives of two innocent people - Bridie Gargan and Dónal Dunne - in a doomed plan to ease his financial woes. A massive manhunt was launched and Macarthur was eventually captured in the home of the state's top law officer, Attorney General Patrick Connolly. The scandal resulted in untold damage to Taoiseach Charles Haughey, and the words he used to describe the drama - grotesque, unbelievable, bizarre and unprecedented - coined the phrase GUBU. Here, GUBU podcast-maker Harry McGee retraces these sensational events.
