I accidentally brute-forced a puzzle and now I'm mad at myself.

Is that a thing? Can you accidentally brute-force something?

Anyway...! I have reached room 46, but I'm not too far past that yet, I don't think. No big spoilers please, but I need to to get this off my chest.

I bought >!The Curse of Black Bridge!< and thought I would find a particular solution regarding the computer.

Spoilers ahead >!I'd already picked up from Randolph's notes that the secret Blackbridge admin key would be a three letter surname, due to the comment about not fitting with the usual length. So, I zeroed in on Fodric Lee in the book. LeeF. No? Damn. How about the letter in the guest room signed KL... nope. Tried a couple of others, and then out of frustration I tried alphabetically LeeA, LeeB... I did not get time to reconsider.!<

Now I have >!the admin key!<, but I don't know >!who B Lee is,!< I feel like I totally missed something on the way there, and I'm experiencing a weird combo of highly amused and pissed off.

This game is great.
