Black Mirror III Hints
How can I get the cabinet's serial number?
1 of 8: The brochure says that it's on the back of the cabinet. Unfortunately, its back is against the wall, and it's screwed to the floor.
2 of 8: If Murray copied down the serial number before having the cabinet installed, it isn't around. You'll have to get at the back of the cabinet somehow so you can see its serial number.
3 of 8: Explore around to see if you can find the room that's on the other side of that wall.
4 of 8: If you exit the office and go through the doors that lead to the guest rooms, you'll realize that your room (number 2) is on that wall's other side.
5 of 8: Verify that by examining the floor plan on the wall opposite your room's door, then enter your room and examine the interactive wall section.
6 of 8: Before you start tearing into the wall, you'll need to figure out exactly what part of it is directly opposite Murray's steel cabinet.
