According to Wikipedia: "Gordon Thomas (1933–2017) was a British investigative journalist and author, notably on topics of secret intelligence. Thomas was the author of 53 books published worldwide including The Pope's Jews, Secret Wars and Gideon's Spies.
Thomas was born in Wales, in a cemetery keeper's cottage where his grandmother lived. He had his first story published at nine years old in a Boy's Own Paper competition. With his father in the RAF, he travelled widely and was educated at the Cairo High School, the Maritz Brothers (in Port Elizabeth, South Africa) and, lastly, at Bedford Modern School. His first book, completed at the age of seventeen, is the story of a British spy in Russia during World War II, titled Descent Into Danger. He refused the offer of a job at a university in order to accompany a travelling fair for a year: he used those experiences for his novel, Bed of Nails. Since then his books have been published worldwide. He has been a foreign correspondent beginning with the Suez Crisis and ending with the first Gulf War. He was a BBC writer/producer for three flagship BBC programmes: Man Alive, Tomorrow's World and Horizon.
He was a regular contributor to the Japanese news magazine Facta and he lectured widely on the secret world of intelligence. He also provided expert analysis on intelligence for US and European television and radio programs. His book Gideon's Spies: Mossad's Secret Warriors became a major documentary for Channel Four that he wrote and narrated: The Spy Machine. It followed three years of research during which he was given access to Mossad’s main personnel. The documentary was co-produced by Open Media and Israfilm."
