I am confused. Why does no one assume it was the Merlin that stole it? Isn't he the most obvious badass contender?

We also see it happening with the Red Court so it can't just be the Fallen?

I don't think my theory works on the Red Court. I am more inclined to believe that the Red Court aging was a side effect of the ritual, the older you were the more nasty-juice/radiation-juice you got pumped through you when the ritual completed. Some leeway is probably allowed, mostly because the ritual had inconsistencies (since Bob only had 10 seconds to explain it^^?).

Mab and the Denarians do scare the shit put of him when brought up (hell, he's hiding in Harry's basement from gruesome death by Mab), Shagnasty isn't going anywhere near him, so he has no reason to fear, when he was asked about the Kemmlerites he was in full on Necro-Bob mode IIRC, the Archive doesn't go after anybody and I don't think Bob has been asked about the Archive.

Ok, no doubt. But I am still not convinced that there might not be a story behind that. But let's rephrase the question to; what stories does Bob know about the Gatekeeper?

What would happen if the Archive wants the Apocalypse?
 (..replace google with a photo&description of Belshugruaubb the Worldeater?^^)

Did Justin die in his body?

Are all encryption techniques absolutely useless against intellectus? Or any faerie?

Î ask since faeries seem to understand "all"?? languages (encryption can be seen as translating something into a "unique" language), though asking a dewdrop fairie to decode the nuclear launch codes seems kinda overpowered^^.
Faerie programmers stealing all my jobs!11

If I write a book in the Nevernever and take it to earth does the Archive know it?

edit:

"I'm not sure it does," I said. "I got word today that the Gatekeeper-"
 Bob shivered.

Why does Bob shiver at mentioning the Gatekeeper? he dislikes hindsight?

1 ) Harry usually has a few supporting characters in each book.  Who do you think will be the main sidekick in Cold Days and in what way will they help?  Who else will have a significant contribution to the plot?

Main: Cait Sith and he will be no help at all. Side: Lash & Molly.

2 ) At the end of Ghost Story, Harry has said goodbye to all his friends in Chicago. 
a. Who will be the first friend to find out Harry isn't dead? 

Murphy after soulgazing she will deck him. Then Molly will curse at him. Then Mouse will flatten him. Lastly Charity will punch him. Lash will comment on his choice of women. I officially coin the term punchhug.

Murphy is first since she is the easiest to find and Thomas comes once Murphy calls him.

b. What shenanigans/snark will Harry use when he "re-appears"?

Mab will open a portal for him, it will lead to his grave ..which has been filled with earth.

c. Who will have the coolest reaction?

Molly, she will be frickin angry and go full nightmare porn on the presumed Harry illusion.
oor
Harry - Hey Mac
Mac - grunts & gets Harry a free beer

d. Who will have the most touching reaction?

Mouse, Harry will need a towel.

3 ) In nearly every book, Harry usually comes up with a new powerup/tool/way of making things go boom.  Given that he just became the new WK, what new abilities will he rely on and which new ability will be the most useful to him during the story (and how)?

His primary powerup will be using his future-sight to sense bullets, he will be pretty hard to assassinate.
Fire&Ice grenades, a miniature sun surrounded by an equally cold ice shell, upon impact interesting things happen.
Harry will tell Caith Sith to do stuff. Sith will do it badly. After a while Harry gets foxy enough to outfox the malk ..sometimes.

4 ) Harry generally has a "Big Bad" to worry about.  In fact, according to the blurb, Harry is going after someone very specific.  Who will that enemy be, and how will Harry take him/her/it down?

Thorned Namshiel. He will use the coin as soulfire battery.
Lasciels revenge will be a secondary plotline.
Several Formor clashes but no definite victory.

5 ) Harry usually faces some sort of "Choice" in every book.  A point where the easy way out will cost his soul/humanity in some way. According to the blurb, this book will be no different.  What will be the most crucial "choice" Harry makes?

Doing what Mab says no matter the cost.
Or between doing what Mab says and what she wants.

6 ) As the new Winter Knight, Harry is pretty much garunteed to encounter his Summer counterpart -- Fix.  What will their interactions be?  Will Fix survive?

Fix will be very far away. Harry will wave at him. They might talk a bit by shouting over the distance.
Or they will fight by very artfully missing each other, hard on the terrain though.

7 ) Jim has mentioned that it's about time now to start revealing some of the motivations/dealings of the shadowy figures working behind the scenes (i.e. what Harry calls the "Black Council").  What Black Council secrets/actions will be revealed in this book?

How Mab was wounded. Who was on the attack on Arctis Tor. A Cowl - Formor connection.

8 ) There are many WAG theories on the boards.  Write up to three WAG theories you believe are correct that will be confirmed (or at least have evidence in favor of) in Cold Days.
Cowl is Justin.
Kemmler is alive.
Mab repaired little Chicago.

9 ) Extra credit:  Write down any prediction about that you think might improve your final score.  Only issues aluded to within Cold Days will be counted.
Mab is/was pregnant.
The white god is the sun.
Molly makes full Council in this book.
Harry visits Susans grave.

"Dodging Bullets" by Harry Dresden

*Love serving mankind XD

Is there something left of Sanyas I-was-a-Denarian package? (like Harrys, languages, guitar++..better liar)

Can Harry build a working little Chicago on Demonreach?

Didn't Harry get the improved strength package with the WK mantle, so shouldn't his degenerated muscles still be able to lift his body weight?

Will Anna Valmont reappear (someone that hit Harry that often on the head.. has to be a recurring character^^)?
