You could also ask "Does the guard to paradise lie?" If the guard to paradise is a liar he will say "no" (which is a lie because he does lie). If the guard to paradise tells the truth he will say "no" (which is the truth). In which case the guard to death says "yes." (If he is a liar he will say the truth teller lies, and if he tells the truth he will say the liar is a liar). This means in either situation if the guard says no, take his path. But if the guard says yes, take the other path.
