Offered for comment

This idea came to me yesterday around dinnertime, and grabbed me so hard I didn't stop writing until five this morning. It's only about halfway done, and fairly rough yet, but I'd appreciate whatever feedback anyone cares to give me. I warn you that sentences run not merely on, but actually rampant, liberties are recklessly taken, and you all know how much I love a good split infinitive. (I'm afraid I may have gone bit too far in places; feel free to whack me with a ruler if it's warranted.)

This is, god help me, Harry/Draco slash, and a bit dark in places at that. I'll give it an R rating for language, violent themes, and repeated references to buggery, but any explicit acts of sodomy take place discreetly offstage.

( In which Draco explains to Blaise why he's going to kill him, in the form of a very long letter. )
