Marian Cockrell was a novelist and screenwriter. In 1945, she published the now-classic children's fantasy book Shadow Castle, which was successful enough for a second printing in 1964 and several additional reprints in the early 1970s. She never published another children's book, but did get six novels for adults into print, along with short stories in magazines such as The Saturday Evening Post and Redbook. She also worked as a screenwriter for films and television programs, including Batman and Alfred Hitchcock Presents, as did her screenwriter/director husband Frank Cockrell. Her daughter Amanda Cockrell also became a novelist. In 2000, Shadow Castle was reprinted by the Authors Guild in conjunction with Amanda Cockrell through a program called backinprint.com. This version included six additional chapters that were cut by the original publishers.
