wall. Try to push the shiny red button again. Push the darn button, already!

Eliminate the large wylebeast. This is optional unless it is revived before speaking with Samuel.

Return to the reception desk and interact with Samuel.

During the conversation, the casebook entries "The student's request" and "The lab is clear" will be removed.

After the conversation, the casebook entries "Lab flask", "The guard's plea" and "A key to the lab" will be removed and you will receive new clues.

Go back through the doorway to the right, but this time open the door directly across the hall and go upstairs.

Go through the next couple doorways and enter the office of Prof. George Cavendish.

Interact with the slightly crumpled page on his desk to receive "Draft of an article" (Lore, Documents, Evidence 5/7).

Interact with the block in the left cubby of Cavendish's desk and use Mind's Eye (a special ability to see visions of the past) to focus on the vision of the past. You will receive "George Cavendish made a spare key" (Mind Palace Clue), "Soap vision" (Key Evidence 6/6), and "Key Evidence Collected".

In the Mind Palace (a mental space to connect clues), combine the clues "Westerbrook has access to poison" and "George Cavendish made a spare key" to create "The poison thief" (Casebook, Quid Pro Quo).

Leave Cavendish's office and go to Prof. Edwin Westerbook's desk across the room. Interact with the page on his desk to receive "Note from Prof. Westerbrook" (Lore, Correspondence, Evidence 6/7).

Use some melee attacks (close-range physical attacks) to "unlock" the door behind Westerbook's desk and enter the tiny storage room.

Interact with the cabinet to find "Bottles of ricin" (Evidence 7/7) and "All Evidence Collected".

Leave the Department of Medicine and the Oakmont University campus.
