Get the Backlight
After solving the boiler room puzzle, head to the piano room and grab the blacklight on the table in front of the piano. If you use the backlight on the floor next to the piano, you’ll spot footprints leading to a wall, which hints that there’s a secret door.
Use the blacklight to reveal hidden symbols on the walls. There are a total of five symbols, revealing the needed code to open the secret door.
Find the Clues
- The first clue is found behind a painting of the river.
- Follow the arrow to locate the second symbol, which is found at the top of the fireplace.
- Follow the arrow for the third symbol at the top of the window.
- The fourth symbol is at the corner of the room, to the left of the piano.
- The final symbol is found next to the chair.
Solve the Piano Puzzle
The puzzle seems straightforward, but many players mistakenly assume the numbers next to the symbols indicate how many times to press each piano key while the arrows show the sequence. The arrows are supposed to hint where to find the next clue, while the number signifies the order.
The order is Mn, Pe, CN, Ao, Pe.
The secret door opens once you have successfully input the right keys and sequence. The basement will lead you to the next series of puzzles that will ultimately reveal the passcode for the Rook Safehouse safe.
