Father and Son Mystery Walkthrough – Indiana Jones

The “Father and Son” quest is one of eight intriguing mysteries in Indiana Jones and the Great Circle, set in the enigmatic Vatican City. This guide will walk you through the step-by-step process to unlock and complete this exciting adventure.

Before starting, you must finish the “A Nun in Trouble” Fieldwork quest. Completing it will reward you with Giuliana’s Key, which opens a hidden balcony door at Borgia Tower. From there, you’ll gain access to a secluded office where the quest truly begins.

Once inside the office, the first task is to search the desk for clues. Here, you’ll discover the first two notes that will set you on your quest.

Note 1: Italian Poem

The first note, an Italian Poem, is located in the desk drawer. This poem is an initial clue and will later tie into the puzzle-solving process.
