Thanks for replying. The clue field says: Clues 3/4 - does it mean that I have found 4 but only solved 3?
When I click on Clues it says:
------------
CLUES FOUND
Cheree [don't know how to put spoiler tags here]
Cheree's body [don't know how to put spoiler tags here]
Cheree once [don't know how to put spoiler tags here]

I see no "???" which means there is nothing to decipher yet I guess. However, I don't recall how many I have deciphered so it may be that the game thought I had deciphered the third even though I was far from finished(?)...
