So I'm in Fallout 2, trying to solve the mystery of Richard Wright's overdose. I've read the Wiki, and apparently I have to talk to Keith to ask him to examine Richard's bedroom.

However, the dialogue option never shows up. Is there something I have to do beforehand? Maybe a skill requirement or something?

I think there is a perception or inteligence requirement.

Its easier to just finger someone, either way you still get the 2nd quest.

Mentats to the rescue! Sure, it doesn't really help my guy's drug habit, but I WANT those experience points, damnit!
