The required veil of secrecy was never penetrated. “We were all terrified by the Official Secrets Act, and thought we’d end up in the Tower of London if we gave anything away,” she said. Her parents thought she was working as a filing clerk. The secrecy lasted only as long as necessary: a few years after the war ended, Montagu published his own account of Operation Mincemeat and it was made into a film, The Man Who Never Was (1956). “Churchill was kept informed, but he did rather dine out on it, which was another reason the story began to come out,” Patricia Davies recalled.
