OK, here goes.
I've gotten to the Dunwich building, explored the WHOLE place (TWICE as it turns out). Found Jaime and killed him (this raises another question actually. Should I have killed him if I'm playing as a good character or was he savable??? I didn't fire until I checked my screen and he came up as a red line so I assumed he was hostile). Anyway, killed Jaime, killed everything in and under the building, listened to all 9 or 10 (can't remember exact number now) of his personal entry tapes, and they kept mentioning a "book" of some sort. So, I assumed this was something I should like to find. It wasn't on Jaime's body, it wasn't in the vicinity, and I ended up going through the whole building again checking and re-checkiing every desk, file cabinet, nook and cranny, etc. No book.
So, here's my specific question. Just would like a yes or no answer. Is there a "book" of some sort to find at the Dunwich building??? If yes, please no spoilers, I will simply go through the building again and try again.
Thanks for any help and my apologies if this should be posted in the spoilers section (I never go there, cause I don't like spoilers. ) Anyway, if this question belongs there, I hope a mod will move it there. Thanks again.
ON EDIT: BTW, I did find a "book" of sorts in the building. It was one of those that you read that increases your skills by 2 points (1 point if you don't have the comprehend perk). Don't really think "that" was the book of which Jaime was talking about in his personal entry tapes though.
