Spy note/ clock key

[Darbyglenfarm21]

PLEASE HELP!
I need spoilers to decode the spy note! I have looked everywhere and cant find somewhere to spy.

I also cant find the clock key. Where is it?!

Spoilers welcome for both, thanks!!

You will find the clock key after you do the spying. And there's a

secret passage

in the basement behind the barrels that you may want to check out to help with the spying(:

I have gone under there but nothing happens?

Did you walk up the spiral staircase?
