What you probably overlooked is that if you ask the liar, you refer to the door he's not standing in front of. That means that it fits: First, let's look at the scenario that you ask the guy in front of the freedom door. If you ask the truth-teller, the door behind him is the freedom door, and he says yes. If you ask the liar, the door behind him is the freedom door, so the door behind the other one (the truth-teller!) is death, which the liar negates to yes. Similar for the guard at the death door, who always says no. | |
