what would your brother tell me?
for instace the village was left, if you asked simply which way? then the liar would say right and the truth teller would say left, but if you ask the liar which way you're would tell me to go, then he would lie and say right and if you asked that same question to the truth teller he would also say right because he knows the liar would lie too you.
hence you know if the guy answers right it's left, or if he answers left then it's right.
