The Secret of Secrets Mystery is located in the southwest area of the Vatican City map in Indiana Jones and the Great Circle. This guide provides a full walkthrough, from starting the Secret of Secrets Mystery to solving it.
Start of the Secret of Secrets Mystery
In the southwest corner of the Indiana Jones and the Great Circle – Vatican City map, look for a passage with a sign labeled “Sistine Chapel.” Enter using Indy’s Priest disguise and go through the only accessible door, which requires the Cleric Key. Once inside, head upstairs and open the desk drawer to retrieve the Planetary Chart. This is the first of three notes needed to solve this mystery.
A smaller table nearby holds a second Mystery Note, called Nicoletti’s Letter.
St. Peter Statues Hold the Secret
Check near the desk for two St. Peter statues you can pick up. Rotate them to inspect the bottoms, as shown in the screenshots below.
Decypher the Code, Open the Safe
Compare the four symbols with the Planetary Chart to find the code for the nearby safe. The numbers on the first St. Peter statue screenshot are easy to identify—it’s 71. However, the symbols on the second St. Peter statue aren’t listed on the chart. Upon closer inspection, you’ll notice the symbol for the number four is missing, likely due to a water stain. For now, let’s assume the number is 44.
The code for the safe is 4471.
Inside the safe, you’ll find a Forged Book. Pick it up, and underneath it, you’ll see the Mystery Note titled “Hidden Note.” This is the third and final note of the Mystery. Collect it to earn 100 Adventure Points.
