A music box. It seems unusable, but it is not. Come on, adventurer, you have come far and you are near the end of the first level. Do not stop now!
The last steps to complete the level are simple, but you will have to remember one more time. Returning inside Lara’s home, up the stairs to the right hallway, and entering through the first door.
As I walked down the final corridor I was waiting for a locked door. If you introduced the previously retrieved music box, you might be able to open the door and enjoy a wonderful music room.
What instruments were there inside?
