A hint before the Bogeyman. To complete the puzzle beforehand, grab the candles from the dressing room in the stage area. Go upstairs and pull the levers. Place the candles on the chandelier and light them. Go back up and raise the chandelier again. Go on the stage and through it. Ring the bells left-left-middle-right-left. Now continue on until some cut-scenes and you fight the bogeyman. Shoot him from a distance or attack melee. Once he goes down on one knee, press A on him to finish him off. If he stands back up, you will have to attack him again. The video actually ends after he is finished off, but for achievement unlocking purposes, it continues through a cut scene and a loading screen.
