A piece of paper with the Windsors’ autographs, old tabloids, gloves, furs, souvenir teacups, photographs, buttons, and other ephemera are displayed amid the jewelry. Another cabinet is bursting with books and 1,500 old newspaper clippings. Beside them lies the FBI file on the Duke and Duchess, who were long hounded by rumors of Nazi sympathies. “The Duke wasn’t very smart, and he was impressed by a housing project he saw in Germany in the 1930s. But they weren’t Nazis,” Baty says, echoing the argument of Hugo Vickers, the British Royal Historian who has written extensively about the Windsors.
