After the nightmare, revealing a bit more each time, the day starts like the previous two. You will receive the white pages listing for the Cazaunouxs who live in the city. Once you regain control, read the newspaper to open the Tulane University location on the map. Then ask Grace for your messages to learn Detective Mosely is requesting your presence for an interrogation of a suspect.
With this done, head back into the bedroom. Grab the black shirt from the closet if you haven't already. Next, use the white pages listing on the phone on top of the dresser. You can call each of the numbers to listen to Gabriel's social engineering attempts, but the number you need is 555-0128. It will be the number with the old lady with the dog Castro. Next, call the number listed for the vet's office. Ask about "Madame Cazaunoux," then choose "I'm worried about Castro" from the second list of options. The Cazaunoux residence will now be available on the map. We have to take care of a few things before heading over there, though. The first stop is the Police Station.
When you arrive, take note of the drummer out front of the station. Head on inside, and go directly to Mosely's office. He will take the badge back here if you haven't been back to the station yet. Watch the interrogation and leave.
Next, head to Jackson Square, and collect the completed veve from the artist. Go across the park to the top left side now. There will be a fortune teller set up here. Wait for her to get up to dance, and use the hand icon when she does. She will drop a veil on the ground, which you will need to pick up. Examine the veil from your inventory to find another snake scale. Pick this up (you'll use the tweezers automatically this time) to add it to your inventory, then use the combine option with the other scale to compare them.
Once you are done comparing the scales, give the veil back to the fortune teller to receive a free fortune reading. After the scene, exit the park through the north entrance to enter the Cathedral.
Inside the Cathedral, go inside the top confessional booth on the left side. Notice the knothole in the wall here; we will use this later on. Kneel down at the kneeler to talk to the priest. Feel free to choose any dialogue here, but once you are ready to proceed, choose "Confession" and then "Womanizer." The priest will then leave for a lunch break. Exit the booth and go inside the middle door. There will be a box here with blessing oil (you can't take it) and a priest collar. Take the collar and return to the World Map.
Leave the French Quarter and go to the Greater New Orleans view. From here, go to the newly opened Tulane University location. The lecture starts as soon as you enter the location. It will be a few minutes long, so get comfortable. Once you regain control, talk to the Professor. Ask about "Cabrit Sans Cor'," "Human Sacrifices," "St. John's Eve," and then any other topics you want to know more about. Once done, show the crime scene photo and the completed veve from your inventory. He'll contact you later on with more information, so head back to the World Map.
Make a quick stop at the Dixieland Drug Store. Ask Willy about "St. John's Eve," "Animal Masks," and "Willy Jr." Now exit back to the World Map and head to the Cazaunoux Residence.
Outside the residence, open your inventory, and combine the black shirt, hair gel, and priest collar to make the priest disguise. Use this on Gabriel (just click on him to bring up the icon menu) and he will change clothes. Knock on the door (the one with the 345 street number above it) and say you are "Father MacLaughlin" to gain entry.
Talk to Cazaunoux and first ask about "Cabrit Sans Cor'." Confirm the meaning of "Goat Without Horns" to have her really open up to you. Next, choose "Human Sacrifice," "Real Voodoo Queens," and then "Voodoo Hounfour." She will then take out a silver snake bracelet for you to say a prayer over. When it shows the close-up of the bracelet, use the clay from your inventory on it to make a mold of it for later use. That prayer is amazing, by the way.
Now finish up any other topics you want to talk about and leave back to the World Map. Head over to St. Louis Cemetery next. Nothing to do here on the first screen, so head straight to the Gedde tomb to run into Malia. After the scene, leave back to the map, which should take you back to St. George's automatically. Watch the cutscene and the day ends.
