This is the secret message of my own cipher. I used a substitution alphabet keyword cipher. Basically, the way this type of cipher works is where you put your keyword¬†to the first letters of the alphabet, and then you just align the rest of the alphabet together minus the letters you used for your keyword. So if your keyword is “frog” then your cipher would work like this:
A=F
B=R
C=O
D=G
E=A
F=B
G=C
H=D
I=E
J=H
and so on until the end. A cryptographer could break this manually using frequency analysis, but I’ll give you two hints. The message is related to my spy character, and I’ll give you my keyword: thorn. The real message is below (SPOILERS):
