The Secret of Crickley Hall is a BBC television adaptation by Joe Ahearne of the 2006 supernatural thriller novel of the same name written by the British author James Herbert. The show was globally distributed by BBC Worldwide. The series presents two parallel dramas. The main storyline, set in 2006, follows the events of the Caleigh family who rent Crickley Hall because Gabe Caleigh (Tom Ellis) gets a short contract in the area; the other is a series of flashbacks following events in 1943 when orphans – who have been evacuated from London during World War II – are living at Crickley Hall.
