    I'd just like to add to the above solution by saying that there are 23 stones that need to be scanned

    The 24th and final message is unlocked when you scan the room mentioned above by Wottstar83

    This room is located in the center of the security control room in the penitentiary. It is the guard tower looking room in the center of this control room.

    To scan simply walk to the entrance of the room, and click and hold left bumper to scan.

    JMJimmyThis is somewhat misleading and relies on another solution...

    You make it sound like you walk into the security control room and take a scan, this of course doesn't work. You need to look at the floor inside the tower and take the scan.

    Once you have unlocked all the Spirit of Arkham stones, return to the penetentiary. Go past the green mile to the control room where you rescued the warden. Take a scan of the room to unlock this achievement.
