First off, as a child of the late 70's and 80's, the subject hits home with me. Most younger people give me the exact same reaction Chas. gets when I mention the Soviet Union. Here in the States, especially where I live in Washington state (Seattle area), we're dealing with a wave of Socialism taking over the political system. I cross-reference now with Soviet socialism and I get blank stares. You hit that right on the nose and I loved it. Your topic and your storyline will hit home with a good audience. It's not going to play to the young. It will play to the middle-aged fan base that kind of slips through the cracks in today's market. Charles' quirks run from the usual (drunkeness) to the odd (talking to stuffed spiders). Using a good mix creates a good character. Charles isn't a typecast; he's a unique character afflicted with typical problems (making him believable) and atypical quirks (making him a likeable oddity). You're doing well with him.
Now for the unfun stuff...
I've noticed that there are places where punctuation is used very oddly.
Charles wiped his brow; massaged the crown of his head, collected the dossiers, slumped into his chair; and contemplated the events that were unfolding at a speed he had not anticipated.
Mixing semicolons and commas. Run with commas for separation. Use semicolons to separate two complete sentences in one run or, less commonly used, as a listing comma. Check through the work for this as I see it quite a few times.
He hadn't been convinced the already dubbed the dawn of a new era would
Here, you're using a title of sorts so throw single quotes around it:
He hadn't been convinced the already dubbed 'the dawn of a new era' would
It allows the reader to pull away from the double 'the' used in the sentence that would otherwise be awkward. I'd recommend pulling the second 'the' anyway and stick with 'dawn of a new era'
Luckily, they did not know about Fred.
This comes in the middle of a paragraph that you started talking about the den. I realized Fred is in the den and both the den and the spider would bring Charles ridicule but you make a severe jump here. A new paragraph seems in order and a tie in would help bring the two jarringly different statements together.
by a tsunami that would wipe away everything
A tsunami? There's no mention before or after of a natural disaster. You say that Charles believes there's a conspiracy. While I'm all for using hyperbole, you need something connecting. A tsunami of what?
One more quick note and then I'll shush. On page six, you suddenly jump from Charles' perspective to Sam's perspective. Having been a victim of that myself, I can tell you it's a pain in the butt. Editors and readers get confused at the sudden change. Jumping from one to another is fine but put a break in between to let the reader know there's a jump coming.
