I am getting some information together for a short story I'm writing and have exhausted my efforts with Google searches. I've discovered Monopoly boards, pipes and shoes with secret compartments but nothing on what I'm really looking for.
One of my characters to will reference how WWII POWs (irregardless of nationality) communicated right underneath the guards noses as part of a story he's telling. I'm specifically seeking hand gestures if possible or even something as simple as leaving an object in a certain spot.
I'm hoping to find a signal which the character can then implement with his team in the modern day an an homage. Thank you.
There's an example in Pat Reid's Latter Days At Colditz of a network of 'stooges' (POW slang for look-outs) used during the construction of [The Colditz Cock] (http://en.wikipedia.org/wiki/Colditz_Cock); one stooge observed the courtyard from a bedroom, and placed either a white towel (all clear), blue towel (silence - goons in the building), green mustard pot (stand by for danger) or red metal salt jar (quit workshop at once) in the window. A second stooge perched on a beam in the workshop, looking at the window from a gap in the roof. In case this system failed there was also a backup, involving an electrical circuit that could be broken by a stooge in the lobby, causing a light in the workshop to go out and a nail to drop from an electromagnet into a tin basin, in case the light was missed.
