You can unlock this one in Chapter 6: Revelations. If you miss this on the first playthrough, you can go back using chapter select. This method should lead you to unlock both this and True Detective for leaving no traces and finding all of the clues.
When you get into the apartment, you will see several doors you can open.
Enter the first door to the left to enter the
bedroom.
Open the bottom drawer
below the TV to find a classified file. Read it
and Take it
. Close the drawer.
Continue clockwise to find a laptop on the chair. Read the article and Put it Back
.
To the right of the bed, there's a nightstand. Open the bottom drawer to find a pink file with cacti on the cover. Read and Take. Close the drawer.
Leave the room. Close the door on the way out.
The next door on the left is locked for now and the doors to the right lead to an irrelevant cupboard (contains zero Harry Potters, either) so we can move on. You'll come to two doors at the end of the corridor. Ignore the left one as it leads to an irrelevant bathroom, unless you want to check it out.
Enter the last door to find yourself in an
open living area/kitchen space.
Immediately to your left, you'll find a brown file containing an important password next to a potted plant. Read and Take.
Optional: Be sure to check out the drawers below the TV for some nice film references (Kill Bill, Jurassic Park, La La Land etc.)Enter the kitchen area and pick up the file on the table. Read and Take. You will also pick up a key that will grant you access to the locked room from earlier.
Return to the hallway after closing all of the drawers and doors and enter the
previously locked room (next to the phone).
After the cutscene, interact with the laptop in front of you, read and take.
You should now see both trophies pop up as the chapter continues.
