To begin the A Date to Remember mystery, you need to pick up the Shipment Report inside the tent in the southwest corner of the restricted area in the Belvedere Courtyard. Picking it up will add the mystery to your journal, along with the location of the tent containing the locked container in the Museum Wing garden.

To access the restricted area, equip the Blackshirt Uniform since guards will not allow entry in the priest outfit. However, keep in mind that the Nazi Captains can recognize you even if you are wearing a disguise.

What is the solution for A Date to Remember mystery in Indiana Jones and the Great Circle?

Use the codes to decipher the code (Image via Bethesda Softworks)

Inside the tent, locate the following clues to solve the mystery:

• Secret Delivery Letter: Includes the date "October 15" and the code word "DICE."
• Calendar Page: Marks "October 20," a Wednesday, as the arrival date of the container.
• Code Lookup Table (in the drawer): Lists numbers corresponding to days of the week and letters from the code key.

The shipment report and handwritten note reveal that Hector De Luca incorrectly used the arrival date (October 20, a Wednesday) instead of the shipment date (October 15, a Friday). To unlock the chest, decode the shipment date, "October 15," and the day "Friday."

Use the Code Table to cross-reference the letters "DICE" with the numbers for "Friday":

• "D" = 6
• "I" = 3
• "C" = 8
• "E" = 0

The correct code is 6380. Enter this code to open the red ration chest and collect the rewards:

• Cash
• Giovanni’s Letter
• Vatican Medicine Guide

You can use the Medicine Guide to find all the medicine bottles scattered across the Vatican City in Indiana Jones and the Great Circle.
