Examine the old wing | Chapter 4 | Walkthrough Black Mirror Walkthrough

The conversation has finally ended. Approach the rightmost corner of the long table and look at the floor to find a photograph fragment.

Take a look at all of the items found on the long table. These are as follows: bloodstained piece of paper, a bottle of rectified alcohol, a lit candlestick (there is a map behind it), a large empty bottle, and two photographs.

Now, examine the large desk found in the center of the room. Take a look at a small shiny globe on your left and pick up an additional piece of a photo found on your right. The bottom left drawer contains a part of the key to the master study - pick it up and investigate the single drawer found in the middle of the desk.

Unlocking the middle drawer in Edward s desk

As you can see, you'll need a key to unlock the drawer. Open your inventory and find the key David has used to unlock the master study and attach the newly found part.

A correct setup of bits needed to unlock the locked drawer

Time to set the bits to match the lock found in the drawer. Set the first movable bit to mirror the one found above it. The next two should be placed 90 degrees left, while the final ones (those newly attached) should be placed opposite to the previous ones all the while maintaining the 90 degrees angle.

Open the drawer and pick up Cecilia's letter to Edward. While you're at it, read a fragment of Edward's memoir regarding the abandoned village.

Walk up to the table located next to Leah. Take a look at the books and check the contents of a crate found in the middle of the table.

Investigate the large metal coat of arms that has been shot down by Andrew (found right from Dr. Farber and marked by a large red square).

Proceed to the footbridge and take a look at the chasm (on the right side of the desk). David will say that it is too dark to see something.

Return to the long table. Pick up the map (pick it up right away, as otherwise you'll have to backtrack later on) and click on the candle found next to it. Pour the alcohol from the tall to the empty bottle and place the stained piece of paper inside it. Use the newly prepared bottle on the candle. Thanks to your efforts, David will be able to see the end of the chasm.

Return to the castle by utilizing the stairs on the other end of the footbridge.
