Saturnalia

To finish Claudia's arc, you need to find the truth about her aunt Mara's death and bring the culprit to justice. You can find Claudia at the bar. She won't want to come with you, so you need to search her house for a reason to get involved.

Explore around town for a while and you will see a man with a lantern running about. This is Claudia's father, and you can follow him to their house if you don't know where it is. Hide around the corner until he comes back out and you will be able to get into the house to investigate. What you are looking for is Mara's diary in her dad's room, under the bed.

Take this back to Claudia at the bar, she is hiding in the bathroom now. Play through the little "a few hours earlier" scenario, and now you can play as Claudia. For now, it's easiest to keep exploring as a different character because Claudia's dad will send her back home every time he catches her. You need to go to the ancient olive tree in the nuragic site and use the scraper on the wall. After examining the memorial, find a bulletin board with an old politely campaign poster on it. It should be near a small alcove with a door you can open. Scrape the poser off to reveal another clue. Now you should head to the Hunter's house, which is always near the pharmacy, up some stairs. Use the wrench to open the door. At this point you will need Claudia.

As Claudia, return to the Hunter's house and check the travel brochure on the side table. This will give you the code for the safe in the next room. Open that, get the letter. Now it's time to confront your dad. You can wander around until Gabriele catches you, then talk to him. He will deny any involvement and take off running. He won't try to catch you anymore, so head to the school and unlock it with the soldering iron. The first door on the right will have a filing cabinet that you need to check. Now go to the church. There is a bulletin board of sorts on the second floor that you need to check. Then go back to Claudia's house and check the toy chest in her dad's room. Take the doll you find back to the olive tree and hang it from the broken chain. Now you want to run around and find Gabriele. Chase him to the tree and he will stop running. There is a bell here, up some stairs behind the tree. Go ring it. This will end Claudia's arc.
