My orders were always the same, to discover new coding codes and to send them to the command, and for the shipment to be safe I had developed a particular code, it was a family code, or rather referred to the family.
I was supposed to write home, commenting on my trip and asking for a relative, and according to who I was asking for, they could tell if I had found something or not. It was a very simple key, but thanks to that difficult to decipher, because for anyone who could see it, it was nothing more than a letter to a relative, of the many sent by the soldiers.
When I managed to get someone's code, then I did a special shipment, a small tourist gift wrapped in newspaper, and in it, indicated with invisible ink, the characters that formed the decoding key of the message discovered.
