ELOISE UNDERCOVER

France, 1944. 12-year-old Eloise’s father has not come home in over a week, and she is getting worried that something might be badly wrong.

Do you know that this says? 

It says Morse Code!

Morse Code is a series of dots and dashes used to send individual letters of the alphabet. If you use it over a short wave radio the long and short tones are referred to as dits and dahs. You could also use a torch!

Morse code was used during WW2 because it was the simplest, most recognizable and understandable signal to send. Online encoding didn’t exist yet, so the safest way of making sure your message was secure was to encrypt it yourself, then send it. Someone at the other end would write down your message, feed it through the same manual decoding system in reverse and… voila! 


Could you be a covert code breaker? 


Here’s an example of a substitution cipher. Each letter of the alphabet has been substituted with a code letter. 

HINT: Sometimes it helps to work on the short words first (notice how NBY is repeated several times!) 


Here’s a question for you written in code. Can you crack it? 
QBUN QUM NBY ZCLMN MUNYFFCNY NI ILVCN NBY YULNB? 


Here’s the alphabet to help you. 
ABCDEFGHIJKLMNOPQRSTUVWXYZ 

Got it? If so, congrats, you’re on your way to becoming a spy! If not, here’s the key: 


Question: 
QBUN QUM NBY ZCLMN MUNYFFCNY NI ILVCN NBY YULNB? 

Key: 
ABCDEFGHIJKLMNOPQRSTUVWXYZ 
GHIJKLMNOPQRSTUVWXYZABCDEF 

You can use random orders and patterns, but in this case the alphabet has simply shifted 6 places to the right. 


Question: 
QBUN QUM NBY ZCLMN MUNYFFCNY NI ILVCN 
WHAT WAS THE FIRST SATELLITE TO ORBIT 
NBY YULNB? 
THE EARTH? 

Answer: 
Sputnik 1
