SSG: Spy/Spec-Ops Group discussion

If you'd like to see how WWII's greatest spy used secret writing and invisible ink (with several photos from MI5 archive files), and how the British developed it, see my article here: http://bit.ly/1Qnwjzk

I came across frequent mention of these techniques in this book I read recently, (which you surely must know of)

Heavily relied on in WWI by the Brits

Also little tricks such as typing their code on strips of linen (so that when sewn into the lining of a greatcoat, it would not rustle)

Another: typing the messages always with a wastepaper basket and kerosene at the table --for quick destruction

Oh--and a nifty trick: one courier carried his messages types on wax sandwich paper, (he would wrap a large sandwich in them) and then casually eat the sandwich as he was being processed through the border. If there was any trouble he would throw the coded messages away with the scraps of half-eaten food. Right into the wastebasket at the office.

Fabulous! Love the sandwich idea. Reminds me of the Cold War Soviet spy who would take a chocolate candy bar, melt it in a pan ... pour half of it back into the wrapper frame .. insert his microfilm ... then pour the remaining chocolate in. Refrigerate, reseal the wrapper and voila!

Popov also was given matches that would write in invisible ink but I thought i'd save that one for later. :)
