Spies, secret agents and spooks of London

From the dark and dangerous alleys of Tudor London to the busy streets of today's city, spies have always found plenty of work.

You might not know who they are (well that's the point, really, isn't it?), but no doubt they know who you are!

Look through the spyhole at: how the Gunpowder plot was uncovered; who the highest-ever paid spy was; Elizabeth I's wily spymaster Sir Francis Walsingham; the code-cracking boffins of World War II; death by poisoned umbrella on Waterloo Bridge; the real James Bond; and the wacky exploits of Boys Scouts founder, Baden-Powell.
