I think it's best to lie from a character's point, or from a narrator that has a set personality/bias etc., rather than the dry, omniscient third narrator. Then it's just.. I don't know, annoying? Sometimes it gives the impression that the author doesn't have a clue, and is forced to resort to rearranging the laws of the universe to make a resolution- other times, it gives an impression of "HA, I TRICKED YOU!!" At the very least, it sort of breaks the sense of ''third person narration'' you get.
I personally like having characters lie outright to others, and other than very vague hinting at the deception, having other characters just follow that until the truth is revealed. Then again, maybe this is because I have a character that lies a lot to the people in her group.
That's true, if you're doing third person narrative, it's not like you can make the narrator surprised, unless you're not doing the omniscient view (which tends to be almost all of 3rd person views I've seen). It's not like you can have someone talk about what's happened in the past, and can see anything, and then go "Oh, wow. I'm surprised as you are. No really!"
If you do a third person camera view, like a movie, then you *might* be able to pull it off, but I haven't seen it done in a novel just yet.
