"I've nothing else but two quick statements... One, Could you go over your case files again. See if there is any reference in any way to the Carlyle Expedition or members of it. Something about that expedition was what Jackson uncovered and what got him killed. My gut tells me that these are all related somehow, but so far, the evidence doesn't seem to pan out. There are rumors that some members of the expedition, even all of them, survived somehow but disappeared. This is only because none of thier bodies were found. Me, I'm betting they're dead... but you never know. Second... a question really. I think I need to show this symbol to some practicioner of "magic" and occult rituals. I'm thinking now that with the absense of this mark on anyone but Mr. Elias, that it is some kind of mystic ward or something used to chase off what ever it was Jackson knew or a warning or some such thing that was not needed on the other victims." Jack says in a "thinking out loud" kind of way.
