Inside Villa Maurel (M17,15), after you kill the thugs, walk into the main study. You will notice a marker for a hidden treasure, which is a key fragment on the table, next to the bookshelf. Also, collect two more in the side wings of the building. With all three fragments, smash the wall in the study, as the fighter, behind which there is a device to fix the key. With the key, go to the door opposite and, after you enter, you can collect the loot.
