Find and explore the secret chamber | Chapter 6: A Man Apart Thief Guide

Note - It is absolutely optional to locate the entrance to the secret chamber. I recommend against quitting the search for this room, because you can find one of the unique collectibles there. Start your search for the chamber still before you focus on reaching the Baron's study.

The letter that hints on the existence of the hidden chamber

You first learn about the hidden chamber, most probably, while exploring the villa's ground floor (assuming that your starting point was in the cellars). Inside one of the chambers, in the Western part of the building, you will find a letter (Eastwick's Letter), whose contents will be commented upon by your character. At this moment, in Garrett's log, there will appear an optional objective, connected with locating the secret chamber.

The location of the secret chamber has been marked on the map

You can find another document, connected with the secret chamber, at the first floor of the villa, i.e. at the upper level of the library. This is a map (Manor Floor Plan), thanks to which you will learn that one of the "empty" areas has been marked in red ink, if you view the map from the log level.

Before you reach the secret chamber, you can go to one of the small storages, located in the North-Western part of the building's first floor. You can learn about the chamber if you look through the hole in the wall. To gain access to the secret chamber, you need to explore the Western corridor on the first floor. Stop to the North of the pressure plates, connected with traps, and examine the painting shown in the above screenshot. You need to locate two hidden switches and press them, which will grant you access to the old chapel [Northcrest Manor - Old Family Chapel].

You now need to solve a puzzle, where you are supposed to compose the drawings on the left and on the right wall of the sarcophagus. Start with the left wall. You need to manipulate the individual elements to arrange them into the drawing presented in the above screenshot.

When it comes to the right wall you can use a hint and find a hole in the sarcophagus, thanks to which you will get the view of the mechanism. The plan assumes that you operate the interactive elements in such a way, so as to make the weight on the chain go through all the holes (screenshot 1). The solution to this puzzle has been presented in screenshot 2.

The reward for solving the puzzle

If you have completed both parts of the puzzle, in the correct way, the sarcophagus will open and Garret will be able to take the unique crystal (Unique Loot - Heart of the Lion). You can now leave the chapel (you need to examine the painting again and press the two switches).
