Radley was a vampire, who was mentioned by Tom in the episode The Trinity. He was killed in 2005 by the 14 year-old Tom McNair and his father. Tom was staying in the Bristol Hilton Hotel at the time and he had hunted Radley with his father for some time. Hal Yorke knew Radley as well, he said about him that he was a "Big ginger fellow". Since Hal knew him it is sure that Radley was turned into a vampire before 1955, however it is not mentioned how long before 1955. There isn't known much more about Radley.
