Mind if I join?
1.) First and foremost, pay The Rat something, pronto. Dude just saved our land, our liberty and our life. Find out what he wants, perhaps suggest something of the shiny gold/silver/gem-set-in-it variety. We will need him later. Let's keep him on our side and hope he keeps knives out of our back. Make it clear we appreciate him and -- without being pushy at all.
2.) Spend some time with the spouse. Happy wife; happy life.
3.) Start thinking about getting our connections in order. Ask the merchant working for us, Victor Irlof (if I got the name right), how things work in this place. Are there guilds or merchant companies? However things get traded, we need to figure it out and figure out how to start influencing that so among other things we can start enticing stuff to us and keep an ear out for the next lackey merchant the count tries to use. If there is no structure (guilds etc) in this place, then ask our merchant about how we could go about setting that up. Don't do anything yet, but consider building guildhalls in the future, holding organized guild contests at our festivals, etc, etc. Find out what kind of things our allies (the two knights and the industries in their towns) need and consider finding a way to provide it or trade it to them.
Nothing cements alliances like fattening your allies' wallets legitimately.
4.) Make believe you do not suspect the count and if possible like you are still loyal to him. I mean of course the one who drinks too much and likes to try and kill us.
Always forgive your enemies. That way they never see your vengeance coming.
Find his weakness. Exploit it. He likes the drink Pay as much of your taxes as possible in wine to keep him good and drunk. Consider subsidizing it if possible. Consider paying him a little more in wine value than he would've gotten in coin. More wine for him, less coin for him. The more drunk he is, the less clearly he'll be thinking. He'll either screw up at some point or drift into inebriation instead of assassination. Send in quantity only so he doesn't think we're trying to poison him (we probably shouldn't poison him when constantly drunk will do just as well).
Figure out what the count's drink of choice is and where he gets it.
Keep in mind that the count probably has spies in the duke's court and thus knows that we implicated him. Make believe we think it was just the wool merchant for now, should it come up.
Consider having the masons/ builders build more complicated housing for your people.
One of our biggest assets is living space. Condos and apartment complex like places will save some space and allow us to offer more of that to the right people.
A consistent enticement we have repeatedly used is giving people a place to live as a recruitment tool. We want to attract, train and retain top talent in industry and military.
Have somebody survey our land to figure out where we can build walls on the edges.
I'm not sure how much time it would take to do all of these things, break them up if necessary, assuming people even want to do them/some of them? Up to you really.
