You begin the Collegial Mystery puzzle at the very beginning of the Order of the Giants DLC in Indiana Jones and the Great Circle. As Indy, you visit the Casina Pia, which then eventually leads you to the underground tunnels of Rome. 

But we won’t do that just yet. Instead, go to the upper floor of this building and take a right till you enter a room with a safe. Head to the desk on the western end of the room, and you’ll find a letter. Interact with this letter to begin the Collegial Mystery. 

How To Solve the Collegial Mystery and Acquire the Safe Code

The clue to solving the Collegial Mystery and acquiring the safe code lies underneath a chair on the western end of the room. Acquire this note and you’ll get the following information: 

  • Consider the number of Apostles when our Lord washed their feet.
  • Reflect upon the multitude of Cherubim bearing witness to the Nativity of our Savior.
  • Count the number of beasts present in celebration as the prodigal son returns to his father’s embrace.

If you notice, all of these sentences are referring to numbers in some way. Furthermore, these sentences are also inviting you to look at the paintings in the room. As you look at the paintings, you’ll notice that there are 12 Apostles, 2 Cherubim, and 2 Beasts. This means the safe code is 1222. Unlocking the safe will then net you two documents and the Hard Crust combat adventure book.
