Hmm, yes, try. I don't know how exactly you're supposed to replace the number in the Caesarian shift with z. Unless you mean using 26. But that would be redundant. Also, there's the matter of the keyword. I mean, what are you supposed to do with that. But you try your idea. Maybe I'm just overthinking things.

I didn't think so. The only one I know that uses everythig we have is the Keyed Vigenere cipher. But I just couldn't get that to work. 

Well, what else would it be? I tried anagraming it, but nothing came up. What do you think it is?

It's killing me. I have to finish it, I just have to. 

I know. is there anyone here who has actually solved this?

I don't know who Kazza is. Well, I know she's a modertor, but that's about it. So she doesn't frequent the board anymore?

I see. I keep thinking. And the most obvious one would be a Caesar shift. I mean... the inscription is in Latin and it's probably the best known cipher there is. But I have turned those letters in every way I could think of using every kind of Caesar shift I could think of and nothing seems to work. 

Is the magnifier that thing on the desk in chapter three?

No, did you zoom in on chapter four? 

Oh no, you're not going to see it in the picture. Just look around for something that is extra, unlike on the usual pages. (hint: what you're looking for is not in the actual picture)
