Code Breaking 101 - Module 04
Invented by 15-year-old Louis Braille in 1824, braille uses various combinations of raised dots in a 3x2 grid to symbolise different letters, numbers and other characters. Louis himself had lost his sight in an accident; his writing system is now used by the visually impaired all over the globe.
In the world of espionage, this system of raised dots can be used to leave messages which can be read discreetly without the agent needing to look at the message. Messages can also be left using stones, bottle tops or other small items to mark the dots.
