The one question that guarantees a correct answer, no matter if the Indian is a Liar or a Truth Teller is:
"If I came here yesterday and asked you how to get to the Truth Telling Village, what would you have told me?"
Obviously, if you are talking to a Truth Teller, he would have given you the proper direction.
But a Liar would've have lied - and sent you the wrong way. But because Liars always lie, he now has to lie about what he would've told you yesterday - and send you in the right direction.
