Bon Voyage is the fourth mission of The Da Vinci Disappearance, downloadable content for the game Assassin's Creed Brotherhood. In this walkthrough, the player will learn where to locate the fourth painting of Da Vinci, and get it from a ship without being noticed.

1. The next painting is in the central part of Centro District. Head for that location and enter the house to initiate the memory.
2. You will learn that the paintings are in the harbour and have to recover them before the merchant sails away.
3. The harbour is north of your position. I recommend taking the rooftops to get there so you won't be detected by the guards. 
4. Locate the merchant. After the friendly talk, you will have to beat up Duccio. Stay in defensive mode and counterattack some of the thugs. Then, focus on Duccio. After a few fists in the face, he will escape and seek more help from his bodyguards. He will do that three times, run after him at each time and beat him with your fists.
5. After the beating, head to the boat marked on your map. Get in the water and swim to get close to the boat. Avoid any dectection. Climb on the side of the ship and locate the painting. It is at the center of the ship, surrounded by a group of three men. Two others are patroling. Wait for the guards to turn their back and kill them. Use your assassins to get rid of the group of three.
6. The third painting is now yours.
