The letter reads:
Hello again, Halrien Yakamura. It is time to move, and we must move fast. A riot has broken out among many of the patients, and the guards have begun executing without orders. Things will be dangerous now, so being spotted is not wise. Exit your cell and go down the hall to your right. Keep going straight until you reach the cafeteria. From there, go down the hall on the west. Enter the third room on your right. When you arrive, I will deliver your next instructions. Beware of patients out of their cells.
What do you wish to do now?
