This section of Call of Cthulhu walkthrough guide focuses on chapter 7 called Nameless Bookstore. After fighting the Shambler in the previous chapter, the time has come for a peaceful exploration of the abandoned bookstore.
Inspect the bookstore
As soon as you regain control over the main protagonist, take The Interpretation of Dreams from the bookcase to the right, as it increases Medicine. Next, go left towards the exit and take the Diary of the pastor's wife, Volume 4 lying on the pile of books.
Now, continue within the bookstore and go along the right wall until you find another book you can take - History of Darkwater, Volume 2. Enter the small room to the left, where you will find the History of Darkwater, Volume 4.
Leave the small room and go to the other end of the bookstore. In the penultimate aisle, opposite the counter, you will find Breviary of Medicine, Tome III that increases Medicine. Right next to it, you will find Book of Dzyan that increases Occult. In the next (and last) isle, you will find another such book: Handbook on Anatomy and Dissection, Book II.
In the corner of the room you are in (opposite the bookcase with the previous book), you will find a small box lying on the floor. Take out your lamp to light it, open it and interact with the book - Malleus Bestiarium - in order to read it and increase the level of Occult. Enter the room behind the counter.
Here, you encounter another reconstruction. Before you activate, though, approach the bookcase opposite the entrance and take the book increasing Medicine - Handbook on Anatomy and Dissection, Book 1. To the right, on the floor among the books, you can find the Amulet in the shape of a dog that increases the Occult level. Now, activate the reconstruction.
First, investigate the door. Go a bit forward and investigate the footprint next to the door leading to the small room. Approach the counter and investigate the object lying there. Now, enter the room behind the counter and investigate the painting there along with nearby objects.
Now, investigate the safe and wait for the cutscene to end. Next, inspect the levitating man, Sara Hawkin's silhouette, and the book the woman is putting into the safe. Finally, inspect the man standing behind the painting and leave the reconstruction.
Open the safe
Before you leave the room, investigate the desk - inside, you will find Sleeping Pills, and in the drawer, the Key of R'lyeh file to read. Go to the bookcase located to the right from the same - between the books, you will find the Drake's Memories in which you'll find clues on how to open the safe.
Return to the bookstore's main room and go towards the last bookcase isle. You will find a board you can interact with - behind it, there are two new Drake's Cylinders (2 and 3). Now, go to the small room located next to the bookstore entrance.
Approach the stack of books by the window and investigate the Goblet. Now, check the chessboard set on the table, and finally approach the phonograph and listen to all recordings from the cylinders, as they include the clues on how to open the safe:
- Cylinder 1 - regards the Goblet from this room. Indicated number 5.
- Cylinder 2 - regards chessboards on the table and the chess pieces defending the queen. Indicates number 3.
- Cylinder 3 - regards the books you can find on the counter and to the total amount. Indicates number 9.
Now go to the sage and set the right combination: 5, 3, and 9. Accept your choice. This will activate a cutscene, after which the chapter ends.
