The Winding Stair is a 1923 novel of romance and adventure by A. E. W. Mason, originally published by Hodder & Stoughton. Set largely in Morocco, the story follows the adventures of Paul Ravenel as he seeks to atone for the disgrace that still attaches to his family name due to the actions of his father who many years earlier in British India had been court-martialled after leaving a key hill fort unguarded.
