directly in front of you should be an insert in the wall with a plant arrangement inside. directly next to that insert is a alarm system. if you turn directly to your right. you will see a hallway, leading down this hallway there is pictures at the very end of this hallway. 3, 4 different pictures. you are going to walk towards those pictures and you are going to stop right at the edge of the hallway. right before the black marble line that is on the ground. and you are done.
