I have just got to the spot in the palace where you break those two chairs that are blocking the door way and then you have to climb up that wall and kill that one guy who is standing there. What is the solution to get up to the next balcony that is higher up. I see those two dagger plates but the Prince just runs up the wall and can't reach the dagger plate to stab the dagger into. It's a little too high. I don't know how to get further from here. Did I miss getting something I should have on the way to this point in the game?
