[#69]
Once you're ready to move on with the quest enter Marcella's Tent and it'll turn out that she's been already murdered. It's not mandatory to examine her body, however you would find some stimpaks, ammunition and a key to her safe. Notice that stealing items from her safe will be treeted as an act of thievery. The most important thing to do here is to pick up a new holotape from the table [#69]. Listen to the tape using your Pip-Boy and you'll find out that you'll have to travel to the Dunwich Building in Capitol Wasteland if you still want to destroy the book. Exit the tent and proceed to Point Lookout Pier. If you've already resolved the situation with Nadine and Catherine you will be allowed to leave Point Lookout for free. Otherwise you'll have to pay the fee for using the boat. It would be a good idea to eliminate Tobar prior to completing this quest, because otherwise you would only waste precious bottlecaps.
[#70]
When you return to Capitol Wasteland focus on planning the shortest route to the Dunwich Building. Don't forget that the area around the building is being patrolled by powerful creatures, so you'll have to be careful. Enter the building upon your arrival and start exploring nearby rooms, assuming of course that you haven't been here before. Watch out for Feral Ghoul Reavers [#70], because they're going to be very resistant to your attacks. Eventually you'll have to find a door leading to the Ruins of Dunwich Building.
[#71]
Continue exploring the ruins until you find a door leading to the Virulent Underchambers. It shouldn't be a problem, however don't forget that you don't have to be in a lot of hurry. Explore the underchambers and you'll soon find a passageway leading to the caves [#71]. Eliminate a couple of ghouls here, including the one named Jaime.
[#72]
Once you've secured this area explore the passageway that was being defended by the last group of ghouls. Concentrate your efforts on finding a large obelisk [#72]. Approach this structure, press the action key and choose the first option from the list to confirm that you want to destroy the book. Don't worry about the flames, because the damage received here is going to be minimal. You don't have to return to Point Lookout for any additional confirmation, because the quest will end with you getting rid of the book.
[#73]
SIDING WITH OBADIAH (HANDING OVER THE BOOK): In this case ending the quest is going to be much easier, especially since you won't have to leave Point Lookout even for a second. Once you've acquired the book head topside and fast travel to the Blackhall Manor. Enter the mansion and locate Obadiah again. You can give him the book right away in exchange for 1000 bottlecaps [#73] or you can ask him a few additional questions about Marcella and about the book itself.
[#74]
After you've formally ended the quest you can stay inside the manor a little while longer. Notice that if you follow the old man to the Basement you will witness a cruel ritual [#74]. You can now ask Obadiah about the body on the altar or you can murder him if you want to have the book back. Sadly it won't be of any use to you anymore.
