So the problem(ish) that I'm running into, is that for the clue 'Spycraft', the following connections jumped out to me:
Millionaire - Rich Person, James Bond type imagery
Cover - Cover of Darkness, Subtlety
Disease - More of a stretch, but like, gas-filled espionage rings (James Bond type stuff)
Bug - Bug a phone line
PIN - As in Code, something that might be important.
Winter - A lot of Spycraft films take place in Winter
Bermuda - Also a stretch, but I believe there was a Bond film that took place there.
Plot - Espionage Plot
School - It's something that's learned?
Teacher - It's something that's taught?
Log - Spy's might keep logs/notes.
Berlin - Germany is the setting of many an American Spycraft Movie.
Arm - Arm a bomb.
Bell - Alarms (something you don't WANT, but might be concerned about)
Now, some of those are better options than others, certainly. My top 4 at the start of the game were:
Bug, Cover, Plot, Arm
However, Berlin was a close follow, and with Cover coming up Neutral, I could've seen subbing Berlin in for the fourth...
Except... I don't think Berlin was INTENDED for the 4th, as I think the 4th is left unguessed.
My list of unguessed possibilities: Millionaire, PIN, Winter, Bell
Bell again, I think, would've been clued with Education. So I'm going to pass on that.
That brings me to Millionaire, PIN and Winter.
Spycraft... I don't think I -really- like Winter here. It's a stretch, and doesn't super fit anything else that's been given. PIN/Millionaire is really close. Neither have me concerned about the opposing 'Sandy' clue...
Ugh.
I should go with Miliionaire. I really should.
