Welcome, secret agents! Your mission, should you choose to accept it, is to decode the cryptogram puzzles below. Each letter in the puzzle stands for another letter. Use your detective skills to figure out the secret message!
A cryptogram is a type of puzzle that consists of a short piece of encrypted text. To solve it, you need to substitute letters to reveal the original message. Each letter in the puzzle always stands for the same letter in the real message. For example, if 'A' stands for 'E' in one word, it will stand for 'E' in every other word in that puzzle.
Directions: Use the code below to decode the word.
Code: A=E, B=T, C=A, D=H, E=O, F=S

2. CDE:
3. FADE:
