In 1943, MI5 secretary Hester Leggatt played a vital role in an operation to fool the Nazis, by writing fake love letters to be found on a corpse. Hester's own story remained a mystery until Operation Mincemeat inspired fans, known as mincefluencers, to #FindHester. Erin Edwards wrote to MI5, asking for confirmation that Hester had worked in the wartime security services. Here she tells BroadwayWorld about her own research and eventually receiving written confirmation from MI5 about Hester.
