Britainโs spy agency MI5 is revealing some secrets.
In collaboration with host The National Archives and prepared over several years by the agencyโs own archivists, โMI5: Official Secretsโ is giving the public the chance to see equipment and methods used by real-life James Bonds and their colleagues over the agencyโs 115-year history.
Ken McCallum, director general of MI5, said the agency wanted to be more transparent.
While TV fiction showed the dramatic side to spying, real intelligence work was about โordinary human beings together doing extraordinary thingsโ, he said at an event this week launching the exhibition.

One of the featured items is a 110-year-old lemon, used as evidence against German spy Karl Muller, who was executed by firing squad in 1915 at the Tower of London. Muller used lemon juice to write secret messages during World War I.
