When Allied fighters were trapped behind enemy lines, one branch of military intelligence helped them escape: MI9. The organisation set up clandestine routes that zig-zagged across Nazi-occupied Europe enabling soldiers and airmen to make their way home. Secret agents and resistance fighters risked their lives and those of their families to hide the fugitives.

In her new book, Dr Helen Fry offers a significant reassessment of MI9’s wartime role in the first critical history of the department in 40 years.

Helen Fry is a specialist in the history of British Intelligence. She is the author of The Walls Have Ears, The London Cage, and over 20 books focusing on intelligence and POWs in the Second World War.
