Spy Gadgets in World War II

James Bond is famous for his many gadgets, like exploding pens, jetpacks and laser beam watches. Unfortunately, many of them are made up - real spies don't use jetpacks, though they do use other gadgets. But what did they use before things like computers and lasers had been invented?

During the Second World War, MI5 played a very important part in catching German spies. The Germans sent many spies to Britain to steal vital secrets and carry out sabotage. British agents also went to German-controlled countries to sabotage the Nazi war effort. Agents of both sides used many clever gadgets to help them in their work.
