Read on to learn how to solve the Signs of Trouble puzzle.
Pick Up Gina’s Request In Indiana Jones and the Great Circle

The first step you need to take is to return to the Sistine Chapel. Head to the altar with the cross at the very front of the room. There is a bible on the table with a note inside. Pick up the note and read it. It’ll tell you about a safe in the foreman’s office near the dig site that has information inside.
Go to the Excavation Site

Next, head to the Excavation Site inside the Apostolic Palace. If you have the Blackshirt Uniform disguise, you can get in without trouble. If you don’t, then this area is restricted and guards will be hostile if they spot you.
To get to it, leave the chapel and take the path on the right side of the truck. Continue straight until you enter a building with multiple sets of stairs. Go to the top floor and through the right door. Make an immediate left through the double doors to enter the Excavation Site.
Unlock the Safe In The Signs of Trouble Puzzle

Once you reach the Excavation site, go to the tent on the far right side and locate the safe on one of the tables. Refer back to the note, Gina’s Request, for the code. The code is 1891.
Pick up the information inside and return to the chapel. Place the information inside the bible to complete the mystery.
