While in the restoration room, on the second floor of the museum, leave through the door close to the location, where you found the thirteenth Stone. Then, go along the windows and cross the wall, into the next room. On the desk, you will find another note. Collect it and you will obtain another clue: Ghosts at the museum.
You can obtain the last Straightjacket in room 217. You gain access to it only after you have completed the "Get Past the Ghost Wall" main mission.
In this room, you can use the shower.
