Manu’s Letter Puzzle

Hey there buddies,

It's Wednesday, so puzzle time again!

This time, it's Manu's turn, and as you'd expect from our master secret agent, he's developed a secret code that you'll need to unravel to read his message.

Can you tell what his message is? Comment on THIS blog with the correct answer, and if you're the first to get it right, you'll get a special mention.

I'll give you a clue because I'm feeling kind. Don't let on to Manu. To crack the code, shift each letter down one in the alphabet (so B = A, C = B, etc).

Good luck!
