In 1956 Fielding was hired by Michael Powell to act as technical adviser for the filming of Bill Stanley Moss's book "Ill Met by Moonlight" – the story of Leigh Fermor's and Moss's abduction of General Kreipe, the German commander in Crete. He wrote a number of books; including "The Stronghold", an account of SOE's Cretan operations, and a memoir of his own wartime experiences "Hide and Seek" (which he dedicated to Christine Granville). In 2014 Folio republished "Hide and Seek" with an introduction by Granville's biographer Clare Mulley.
