Problem

This problem follows on from Substitution Cipher and Transposition Cipher



Below is a secret message. It's been double encrypted, first using a substitution cipher and then using a transposition cipher. Can you decipher it?

If you want to work on a computer, you can download the ciphertext as a text file here.

You can then use our Cipher Challenge Toolkit to help you decrypt it.
