The Church and Irish Terrorism, 1997, Dillon explores the nexus of religion and paramilitarism. Dillon interviewed paramilitaries and religious figures to discern whether this is a religious war or one of economics and class. The interviewees included the late Billy Wright, a.k.a. "King Rat", a notorious Protestant assassin killed by the INLA in prison in 1997, Protestant terrorist Pastor Kenny McClinton, and Fr. Pat Buckley who admitted breaking the seal of the confessional to save lives on both sides. According to Publishers Weekly: "Dillon has written an eye-opening book about a sometimes-incomprehensible sectarian situation". In The Trigger Men: Assassins and Terror Bosses in the Ireland Conflict, 2003, Dillon delves into the dark and sinister world of Irish terrorism and counterterrorism. He analyzes the personalities of some of the most dangerous, professional and ruthless killers in Northern Ireland, their motivations and the bizarre crimes they committed. Their individual stories are told in gripping, unflinching detail. Dillon also exposes the ideology of the cult of the gunmen and the greed combined with hatred that motivated the assassins in their killing sprees. He presents penetrating insights into the mindset of terrorist Godfathers and their triggermen like the infamous Protestant assassin Billy Wright, the INLA leader Dominic McGlinchey, "Mad Dog" Johnny Adair, the UDA hitman, Michael Stone, and British terrorist agent, Brian Nelson. Dillon co-authored with Rt. Hon. Roy Bradford Rogue Warrior of the SAS: A Biography of Col. "Paddy" Blair Mayne, 1987. Lt. Col. "Paddy" Blair Mayne is regarded as one of the greatest soldiers in the history of military special operations. He is the most decorated fighting soldier of WWII, receiving four DSOs, the Croix de Guerre, and the Legion d’Honneur. He was one of the six founder members of the SAS and pioneered tactics used today by Special Forces units across the globe. His exploits against Rommel's Desert forces and against the Nazis in Italy, France and Germany were legendary. His courage, initiative and wildness made him a giant among his men. He was, however, denied the ultimate accolade of the Victoria Cross because of his unorthodox rules of war and his resentment of authority. In 2002, Dillon updated the new, revised edition Rogue Warrior of the SAS - the Blair Mayne Legend, 2003 for Mainstream publishing. Dillon added a postscript with new facts about Mayne's conflicted personal life, in particular, his sexuality, which was a topic purposely omitted in the
