Helen has authored and edited over 25 books covering the social history of the Second World War, including British Intelligence and the secret war, espionage and spies, and MI9 escape and evasion.

​She is the foremost authority on the ‘secret listeners’ who worked at special eavesdropping sites operated by British Intelligence during WWII. Her groundbreaking research and extensive media coverage have shed light on one of the greatest intelligence deceptions of the war: the bugging of Hitler’s generals at Trent Park in North London, and thousands of prisoners of war at Latimer House and Wilton Park in Buckinghamshire. Helen is the official biographer of MI6 spymaster, Colonel Thomas Joseph Kendrick. She has also extensively written about the 10,000 Germans who fought for Britain during WWII.

Helen will be speaking about her latest book – Women in Intelligence.  This book is a groundbreaking history of women in British Intelligence spanning the 20th century. It provides an incredible account of the efforts of women across two world wars, with tales of bravery and heroism. Many new stories are told for the first time, shining a light on the hidden legacy of women in intelligence from World War One to World War Two.
