Love it!
Short, sweet, and to the point. This piece is nigh-perfect just as it is. I have to disagree with a previous reviewer who wanted an expansion of the lover's actions, as well as more ministry bashing--those would be nice (maybe as a one-shot, or 'prequel'), but don't belong in Harry's letter.
Nope, having written a few 'fornicate you very much' letters myself, I think that this one is just about exactly right.
Good on you, Harry!
