Introduction

If you’re an Indiana Jones aficionado, you’re in for a treat with the thrilling optional objective “Father and Son,” cleverly tucked away in the stunning setting of Vatican City within the game *Indiana Jones and the Great Circle*. While it may require a bit of extra effort to uncover, the rewards are definitely worth it!

Getting Started

To embark on this intriguing quest, players must first complete the initial Fieldwork mission titled “A Nun in Trouble.” You kick off this mission during your very first encounter with Gina in the game. The adventure then takes you through the Blackshirts' campsite as you sneak into Vatican City’s museum, aiming to rescue Gina’s friend Giuliana from the heights of the daunting Borgia Tower.

Unlocking the Mission

Completing “A Nun in Trouble” yields Giuliana's Key, which opens the door to the “Father and Son” Mystery mission. As hinted by Giuliana, this key unlocks a nearby door in the Borgia Tower—check your in-game map for guidance.

The Hidden Doorway

Initially, this doorway may seem like a mere shortcut to a zipline that whisks you to the street, conveniently placing you outside the famous Fountain of Confession. However, don’t be fooled! It’s the second locked door close to the zipline that holds the real secret.

Treasure Awaits

Using Giuliana’s Key on this door leads you into a storage room filled with treasures: a sleeping dog, a laid-back cat, a locked safe, various documents scattered about, and even a Bandage. One of the documents is an essential Adventure Book that teaches players the Throttle skill, giving you the power to execute stealthy ranged takedowns with Indy’s trusty whip.

Unlocking the Safe

Now, let’s get to the heart of the mystery: unlocking the safe. To crack it, first check the table drawer for an Italian Poem. Although the poem might not seem significant at first glance, it contains vital clues—someone has circled eight letters: I, R, I, A, T, A, S, O.

The Cipher Challenge

Next, look under the nearby typewriter for the Polybius Square Diagram, which offers a cipher for decoding the letters from the Italian Poem. This cipher isn’t heavily featured in gaming but proves essential for your quest.

Cracking the Code

A notable hurdle in this mystery arises from the handwritten cursive letters in the poem. It’s common to mistake the final letter “O” for an “A,” which could throw off the entire code and leave you scratching your head.

The 4-Digit Code

Decoding the circled letters using the Diagram gives you a 4-digit code: - I + R = 5 - I + A = 8 - T + A = 7 - S + O = 3 Thus, the safe’s secret code is 5873.

Rewards for Your Efforts

Once you crack the safe, you’ll be rewarded with the Siwa Photograph, Junior Report, Office Photograph, and Senior Report. Collecting all four documents scores you a whopping 60 Adventure Points, plus an additional 100 points for completing the “Father and Son” mission!
