Since Gerry O'Carroll joined Ireland's Garda in the early 1970s, there has been much bloodshed and plenty of controversy. As one of the force's most distinguished detective inspectors, he has seen his fair share of both. Following his first posting as an officer on the beat in Rathfarham, County Dublin, Gerry spent three decades investigating some of the country's most high-profile crimes, and here he explains the motives behind them and reveals the confessions that led to convictions. "The Sheriff" recounts Gerry's story from his Kerry upbringing as one of a family of 15 children to his professional success as one of Ireland's most well-known policemen.
