Hi Ky,
We will try to update the wiki at sometime but I hope these hints can help:
1. Meet Anthony in the Courtyard during night time hours (moon symbol)
2. Collect books at the Library
3. Get medical bag in the guest bedroom
4.&5. Get supplies from the pantry. investigate the pantry to find his limbs locked up in the adjacent butchery.
Leave enough time to report back to the basement when you've completed all the tasks. Visit the westwing and talk to Isaac or rest in your room quietly to lower suspicion.
hidden bonus: if you visit the courtyard during the day, you have a chance of finding a ghoul wearing simon's hat and can get a relationship boost next chapter for giving him that tip.
