Right now you're facing a closed door. Turn around and exit the room. Now, slightly turn right and you can see a staircase. Get down the stairs, now you're facing few portraits. Turn behind and you can see a passage, walk through the passage till you reach an opened door on the right side. Turn right and walk into the room. After you reach the mid point of the room, turn left and you can see a passage in front of you. Walk towards that passage till you reach a opened door in front of you. Enter into the room, slightly turn right and move forward. Move forward till you reach a cupboard with a monitor and mirror on it. Stand behind the chair and that is the end point.
