Luke Waters came from modest beginnings in Finglas on Dublin s Northside, but nevertheless dreamed of becoming a detective. He initially planned on following in his grandfather s and brother s footsteps in joining An Garda Siochana, but in 1985, America beckoned. After some time as a barman, he enrolled in the NYPD, working his way from rookie through Narcotics before becoming a homicide detective. Waters retired from the NYPD in 2011 and now lives in County Cavan with his wife and three children.
