Skill Question, Detecting Lies

[Nechevo]

What skill would one use to figure out if someone is lieing?

 

I was wondering that at my last Champions session, and went through the skills and I couldn't find a skill that specifically says it can be used to detect lieing.

 

I'm assuming that Conversation would work. Probably Deduction. Any others?

I don't know that any Skill would specifically help to detect that someone was telling a falsehood in all circumstances. I can see situations where Deduction would tell a character that, but other situations where it wouldn't help at all. I think it's probably as much or more a roleplaying/player-makes-deduction sort of thing as it is a Skill Roll sort of thing.
