(3 point Flaw)
This is the next step up from the Flaw: Curiosity, and generally requires more thought and premeditation, whereas Curiosity is a spur-of-the-moment issue.
You're too inquisitive for your own good; even most cats have more of a sense of self-preservation than you do. When a mystery presents itself, you'll go all the way to hell (literally!) to puzzle it out. It's hard to put a finger on why you feel compelled to search out facts, but it often gets you in trouble.
In game terms, this Flaw forces you to make a Willpower roll whenever some question is left unresolved. This question could be anything from an overheard conversation to a lost artifact. If you fail the roll, you'll go out of your way - really out of your way - to uncover the answer. The difficulty for the roll depends on the amount of work it looks like you will have to do. The simpler the question appears, the higher the Willpower difficulty will be. Note the emphasis on "looks like"; many complicated problems arise from something that seemed simple at the time.
