Find the Bookcase Note in Father Ventura’s office
The mystery is in Father Ventura’s office in the Apostolic Palace in the Vatican. The office’s front door is locked; the walkthroughs describe entering through a side door. The palace is a restricted area with patrolling guards, so be prepared to avoid or distract them. PowerPyx suggests drawing guards away with the whip or wearing the Blackshirt Uniform. Guides differ on the floor, so use the office and palace as your landmarks rather than relying on a floor number. Game8; PowerPyx.
Pick up the Bookcase Note from the table and inspect both sides. One side says to take the books alphabetically; the reverse lists the book titles and the symbols shown on their spines. Use those symbol-title matches to identify the books before pulling them.
Pull the books in alphabetical order
| Order | Spine symbol | Book title | Shelf position, left to right |
|---|---|---|---|
| 1 | Crown | Francorum | Second |
| 2 | Triangle | Logicae | Fourth |
| 3 | Wheel | Philosophiae | First |
| 4 | Sun | QDV | Third |
The book titles are alphabetized, while the positions are a left-to-right fallback reported by PowerPyx. Pulling the four books in the listed order activates the mechanism and opens a hidden compartment. Game8; PowerPyx.
