Welcome to the official Author site of historian Helen Fry. She has written and edited over 25 books. Her works cover primarily the social history of the Second World War, most especially intelligence (MI5 and MI6) as part of the secret war and espionage, as well as interrogation of German prisoners of war. Helen continues to publish new wartime stories and bring fresh insight into the clandestine operations of WW2, including widespread coverage of one of the greatest deceptions of the war: the bugging of Hitler’s generals at Trent Park. She has worked very closely with WW2 veterans over a 15-year period and is sadden by the passing of those eyewitnesses into history, many of whom she had built up a special relationship. She has written extensively about the refugees from Nazism who fought for Britain in WW2, as well as operations relating to British Intelligence. Helen has received worldwide acclaim for her books and, because of her expertise in British intelligence in wartime, has been involved in a number of documentaries as well as conducted advisory work for TV and drama. Helen particularly enjoys TV work and remains available for historical consultancy work for feature film, TV and drama.  She lives and works in London.
