As you know, the most frequently occurring letter in English is e. Therefore, the first or second (or perhaps third?) most common character in the message is likely to stand for e. Try to find a character in the ciphertext that decodes to e. 2. The most common word in English is the. Use this fact to guess the characters that stand for t and h. 3. Decipher the rest of the message by deducing additional words
