All at once it struck her. Move a few letters around. Codex. It was a Codex.

It was so stupidly simple. Here she'd been crossreferencing, reading for days on end when it was right under her nose the entire time. Well not under her nose, that was a bit too dramatic. It was more like it'd been posted on a sign in front of her that she'd been too lazy to read.
The Codex Gigas. Once she'd figured the name out, the rest was easy. Too easy for her liking, actually. She felt as though it should've taken more effort, more gusto to find this supposedly powerful book, yet all it really took? A google search, and a click on the wikipedia page. The description on wikipedia was a bit ... different from the notes she'd taken, but then, many things in the "human" world were not what they seen.
For example, she'd noted that the book supposedly held countless descriptions of demons, yet the humans only knew of one. Perhaps they couldn't decipher it? Perhaps FEAR was altering the visibility of the information. Hexes and curses- it was all rather Hollywood, but she assumed a witch of some sort could probably alter the book as such. Whatever the reason was, it was all very shrouded in mystery.
The first thing she knew was that unless the National Library of Sweden felt particularly generous, there was no way to get it. The second thing she knew was that to understand the discrepancies, she need to be in possession of the book.
Well that was useful.
There was only one solution. Write a letter to the big man on top. Of the life division, that is.

Dr. H,
I have reason to believe there is an artifact in Sweden. It is known as the Codex Gigas, commonly referred to as the "Devil's Bible." From what I have gathered, it is an encyclopedia of sorts on demons. I believe it would be in our best interests to recover this book, as it could provide priceless intel for our research.
Enclosed with this letter are my research notes which reinforce my claim. I will not waste your time repeating them here.
Considering we've infiltrated more complicated mechanisms than human devices, I will not require more than a handful of trainees and one skilled Death hunter to provide us with intel- I would like to request Gale Gentry, as he has significant experience. Additionally I will require the necessary equipment for such a break in- headsets, radars; there is a list in the aforementioned research notes.
Thank you for your consideration.
