"One writes this letter on a new hat or on human skin with crushed gallnuts dissolved in water. When the writing is dry it will become invisible. Then soak a sponge with vitriol and rub it over the writing and it appears." - Philo of Byzantium on #secretwriting, 3rd century BC

The main form of communication that agents used with their handlers was #secretwriting. A crucial aspect of the system was the need for genuine information to be sent along with the deception material.

When you're a spy you have to be careful of ANYTHING giving you away, even to the point of not using lined paper, as the lines may run when exposed to invisible ink solutions. From KV 4/172, Notes from the Beaulieu spy school. #spies #espionage #secretagents #tradecraft #history
