Let's Go Treasure Hunting!

Find the secret code word that has been posted somewhere in a previous November challenge. Once you've found the word, come back here and post it as a comment. The first person to do so will win a ticket in the final prize draw at the end of the month.

Treasure Hunt Clue:

"the most difficult letter"

Once the winner has been announced, the code word will be deleted from the blog.

Happy hunting!
