October 2008. The Celtic Tiger had lost its roar and 45-year-old Dubliner Paul Keany's plumbing business was faltering. So he did something he lived to regret: he agreed to smuggle six kilos of cocaine into Ireland from Venezuela for a man he met in a pub. Arrested at the airport in Venezuela, he spent two years in one of the most notorious prisons in South America. His book, 'The Cocaine Dairies: A Venezuelan Prison Nightmare' describes the horror of life behind bars. It has recently been on the top ten best seller list in New Zealand.
