Finished Harry Potter

After 2 days and hours upon hours of reading, I finished Harry Potter
#6. Very intriquing who R.A.B is leaving a note in the fake treasure
Dumbledore died getting. I racked my brain going through past books. Ms.
Rowling has a way of bringing up people and subjects in prior books in
her tales.
First I tried to figure out someone with a last name beginning with B.
The note began with To the Dark Lord, only followers call him that. Next
line was I know I will be dead long before you read this but I want you
to know that it was I who discovered your secret. This had to be a
follower believing he would be killed from betraying The Dark Lord
because he had a conscience, and has been killed in a prior book I
guessed.
I checked Book #4 for when The Dark Lord returned for clues. He said all
his followers knew the measures he took to insure immortality, so not
necessarily a close contact of him wrote this note. In book #5, his
followers knew about the phophecy that finished the note. Figuring the
traitor was not present at The Dark Lord's return, I looked at #6 again.
I was looking for names when the new potions professor talked about his
past students, when I recalled Harry's godfather had family who were
followers, but he was not one and became the black sheep of the family.
I also recalled his brother was killed as a follower. I went back to
book #5 to read what his name was. Regulus Black. He joined the
followers, freaked out, and then murdered. I think I found R.A.B.
He hoped that when the lord met his match that he would be mortal again.
We know Harry is the one who can defeat him. Though it will be
interesting how she will pull that one off. The phophecy said neither
can live while the other survives, so they would both die at the same
time. Though in #4, they shoot spells at each other in the graveyeard
and learn 2 people with the same source of magic in their wands
(established in #1) can not fight each other leaving the lord and Harry
floating in shock. Book #7 I can tell will be interesting.
Too bad Ms. Rowling doesn't give out middle names. I think #6 has
Harry's middle name for the first time. Ms. Rowling will probably change
who wrote the note after reading this. Post later. Bye!
