Mafia: The Old Country Walkthrough - Sicilian Defense 1906
This walkthrough guides players through Mafia: Definitive Edition's Sicily Defense, 1906 mission, detailing how to find Giuseppe, unlock safes, and retrieve the printed edition.
After the meeting, there's a chest in the adjacent room that you can pick.
Head to the marketplace square and ask around with the vendors. Your target is the person wearing a red vest on the edge of the market.

Follow the person in the red vest to scout the interior, then go back at night to rescue them.
Find a way in through the left side of the building.

Wait for the guards to move away, then climb the ladder.

Once you're in the courtyard, sneak into the prison.

There's a key on the table to open the door and rescue Giuseppe. You can also open the door with a knife.

There's an amulet next to the cell door. Be sure to loot the cell as well.

You'll discover that "Shadow," Black Hand's brother, is also being held here.

Enter the building and examine the documents on the desk. You'll learn that the printed edition is inside a safe.

There's a guard at the entrance to the stairs leading upstairs, so you can't go that way yet.
First, explore the first floor. Passing through the dining room leads to Blancati's office.

Look at the documents next to the safe, and you'll find out that Blancati's safe uses the factory default password.

Go to the office across the hall and check the documents there. You'll discover the factory default password is: 00-01-02.

Return and open Blancati's safe. It only contains money, but not the printed edition.

Head back to the office across the hall, pass through the multi-person office, and arrive at Marino's office. (You've completed a full circuit of the first floor.)

The documents here reveal that Marino's safe is still using last month's password.

Check the documents next to the safe, and you'll find out last month's password was: 28-34-12.
Open Marino's safe, and you'll learn that the printed edition has been moved to Diamico's safe upstairs. The password is 02-19-62.

Throw a coin to distract the guard, then head up the stairs.

Diamico's office is in the center of the upper floor.

There's an amulet in Diamico's office. Grab a gun as well, and prepare for a fight.
The documents in the office will also confirm the password is 02-19-62. Open Diamico's safe to retrieve the printed edition.

After the fight, escape and return home to a pleasant surprise.
