For over 100 years, MI5's story remained hidden behind locked doors. Now, with unprecedented access to thousands of declassified files, archivists Mark Dunton and Stephen Twigge reveal the spycraft that helped safeguard British democracy, from surveillance logs to interrogation transcripts and intercepted phone calls. Joined by former GCHQ Director David Omand , they discuss the history and evolution of intelligence work - and how secrets are managed, sometimes for decades - with spy novelist Ava Glass . There will be a book signing after this event . Get ahead of your Festival reading and visit the Waterstones Cheltenham Literature Festival bookshop and support Cheltenham Festivals with every purchase.
