Find Dr Colden
Upon regaining control over your character, investigate the desk in front of you - in the drawer to the right, you will find Diary of the Pastor's Wife, Volume 1. Also, you can find the sleeping pills vial in the document locker by the wall on the other side of the room. If you managed to collect all the vials described in the previous chapters, you will unlock The most trivial object achievement.
Approach the coffee table to the left from the desk - there, you'll find Malleus Bestiarium, Volume 3, one of the bezbozne books - if you collected the ones described in previous chapters (6 and 7), you will unlock the Complete Revelation achievement). Also, the Occultism stat will be increased.
Leave Dr. Fuller's office using the door to your left. Continue leftward along the corridor - ignore all the doors, as they are either locked or hide nothing interesting. Go towards the basement doors and open them to initiate a cutscene.
Upon regaining control over your character, you will notice that the layout of the rooms has "slightly" changed. Guards will be gone, so you do not have to fear to go about the corridors, nonetheless, you need to pay attention to the brightness - if it is depleted, the Shambler, known from the previous chapter, will appear and you will have to restart this checkpoint. Initially, the area you can move in will be limited - it has to be unlocked.
Regenerate the brightness at the control point, and then turn into the corridor to the left. Before reaching the end of the corridor, enter the small office to the right - inside you will find Medicine and Secret Sciences which increases Medicine. Take it, return to the control point and go towards the light through the portal.
The main protagonist returns to the control point. A lamp will appear on the table to your right. It can be used to switch between two views ("dimensions") - the one you are currently in (tainted green) and the more real one. In order to complete this location, you need to switch between these two dimensions.
Switch the view and go to the spot where the energy beam led (the door with the PHARMACY sign). Go through the door and take the Uomo Deliquente from the bookcase. It will increase your Medicine stat. Return to the control point and switch the view to "green".
Follow the beam of light. Go to the Pharmacy again, and then to the next room. Approach the interactive spot to increase the lamp's brightness using the button presented on the screen. From now on, you can increase the brightness with this button - you can use that to unlock pathways, which will prove useful soon enough.
Upon returning to the control point, follow the beam of light until you reach a wall. Increase your lamp's brightness to unlock a pathway. Return to the control point and switch the view. Approach the door indicated by the beam of light and open it.
Return to the control point yet again and change the view to "green". Now, go through the newly unlocked door. Go across the room and through the next portal-door. A beam of light will appear - reach its end and increase brightness to return to the control point.
Stay in this mode, turn into the corridor going leftwards and then follow the beam of light. Approach the light wall and increase the brightness to unlock the pathway.
Return to the control point and refill the oil in your lamp. Now, enter the corridor on your left and when in it, turn left to enter Block A. At the end of this room, there is another wall to unlock.
Now go to the next part of the room, Block B, and approach the desk in which you found the Boiler Room key during the previous chapter. On this desk, you will find another spot where you can recharge your lamp - you cannot change the view, however.
Follow the beam of light that will guide you to a circle on the floor. Increase the brightness while standing by it. Now return to the control point from the beginning of this level.
Follow the beam of light to reach a wall that you can unlock. Return to the control point and switch to a regular view. Follow the corridor to the left and go around the asylum. Open the door to Dr. Fuller's office, but do not go inside. Instead, go to Administration located on the right from the aforementioned door - inside, on one of the desks, you will find another book that increases Medicine - The Reference Book of Medical Sciences.
Return to the control point and switch to "green" view, and then, follow the energy beam until you encounter Shambler again. Now, go to Dr. Fuller's office and shed light on the symbol on the floor.
Now, you will return to the control point. You can go around a bit to unlock more paths, however, there is nothing more to collect. Go to the entrance to the Psychiatric Wing and light it with your lamp.
Finally, the entrance to the Psychiatric Wing will be unlocked. Go there through the same door as Marie Colden in chapter 8.
You will get to a long and dark corridor with many doors. Go in the chosen direction and do not look around - the doors cannot be opened. After a while, in front of you, an image of a cell with the main protagonist locked in it will appear in front of your eyes. Next, you will find yourself in that cell.
The main protagonist will experience panic attacks. Look around the room, and soon an exit will appear. Go towards Marie Colden. After a short cutscene, new doors will appear - go through the corridor to start another cutscene.
Upon regaining control over your character, leave the room and follow one of the available paths. After a short walk, another cutscene will start, during which you learn that... Sarah Hawkins is alive!
Get Sarah Hawkins out
Upon starting the conversation, pay attention to the dialogue option in the top left corner. It is an answer in R'lyehian - if you want to unlock the Fluent in R'lyehian achievement, select this option. During the course of the game, there are 9 such dialogue options - in order to unlock the aforementioned achievement, you need to select them all.
After the conversation comes to an end, follow Sarah - there is nothing to investigate nor collect during this sequence. She will stop by the entrance - after going through it, you will be spotted by the guards and you will have to run towards the corridor ahead. Just run across it until you reach a safe location.
After a short conversation ends, go downstairs and try to turn the valve by the container. You will not succeed, as you need a tool to do it. You can find it by turning by 180 degrees from the tank - there is a Poker right ahead of you. Take the tool and return to the valve.
This will trigger a cutscene and then a conversation with Charles Hawkins, Sarah's husband. The dialogue options you chose do not matter much here - just go through the conversation to activate a short cutscene, after which the action will take you to another location.
Question Sarah Hawkins
You will again find yourself in the Hawkins' residence. After regaining control over your character, approach Officer Bradley sitting on the first floor and talk to him. Tell him what happened to Marie Colden, and in the later part of the conversation select the R'lyehian dialogue option.
Finish talking to him, and go downstairs to talk to Sarah Hawkins and Aldernon Drake. When talking to Sarah, an R'lyehian dialogue option will show up - select it.
Talk with Algernon Drake
After talking to Sarah, you will be tasked with talking to Drake. Go to the office, where you solved the globe puzzle and talk to him. During this conversation, there also is an R'lyehian dialogue option - select it and finish talking to the man.
Find the amulet
Now, you have to find the amulet. Drake will help you by giving you a clue - the drawing of a bust that you have to find. Go upstairs and towards Sarah's room, where you need to perform a reconstruction.
Examine the true on the floor, then the easel, the book on the floor, the circle on the floor, Sarah, and finally, the object by the door, also on the floor. Now, leave the reconstruction and approach the desk, on which you will find the bust you are looking for. You will receive the Sketch of a still-life.
The sketch you receive shows another bust that you can find right next to the place, where the main protagonist woke up a moment before - upstairs, near Office Bradley. Go there, approach the bust, and take the amulet lying there. The amulet - R'lyeth Key also increases you Occultism stat.
Show the amulet to Drake
After the cutscene ends, return to Drake and show him the amulet. Now, go to Sarah, who's waiting for you by the house entrance. Talking to her will initiate a cutscene, after which this very long chapter ends.
