If, like me, you spent your childhood memorising every page of the Usborne Spy's Guidebook, your mind will now be chock-full of top secret, hi-tech spying secrets.
Here is just one example:
Alone in a park, you suspect a rival spy is on your tail. What do you do!?
Of course, you spell a secret message on the pavement using nuts and leaves and somehow disguise yourself as a tree!
If you think that is stupid, then look out: because you've just insulted the world's most famous spy, James Bond!
Yes, James Bond himself is the author of the Usborne Spy's Guidebook.
The most interesting spying lesson within the book is this one: If someone is following your footprints, simply walk backwards into a lake!
The resulting footprints will appear to someone walking out of the lake, and your pursuer will think that the murderous zombie 'Jason' from the Friday the 13th movies is on the prowl!
And it was this very technique that, on the 20th of November, created the longest line of backward footprints.
Chris Jessops was attempting to escape from an angry farmer - when he suddenly remembered the backwards walk... and used it!
Unfortunately, since he was walking backwards, he couldn't see where he was going, and he kept on walking for 322 miles, until he was hit by a train!
WOW!
