It's almost done, actually. Here's a sneak preview of the next chapter:

Dumbledore peered over his desk at young Harry, twinkling in a kindly sort of way. The boy had come to him with a terribly intense look on his childish face - Dumbledore hoped that whatever this matter was, it wasn't too serious. Harry was far too young for his life trials to be starting already. "What was it you wished to speak to me about, Harry?"

Harry James Potter-Evans-Verres leaned forward in his chair, looking bleak. "Headmaster, I got a sharp pain in my scar during the Sorting Feast. Considering how and where I got this scar, it didn't seem like the sort of thing I should just ignore. I thought at first it was because of Professor Snape, but I followed the Baconian experimental method which is to find the conditions for both the presence and the absence of the phenomenon, and I've determined that my scar hurts if and only if I'm facing the back of Professor Quirrell's head, whatever's under his turban. Now it could be that my scar is sensitive to something else, like Dark Arts in general, but I think we should provisionally assume the worst - You-Know-Who."

"Great heavens, Harry!" gasped Dumbledore. He sat there with his head whirling. The boy was right that this was nothing to ignore. He dared not confront Professor Quirrell within the halls of Hogwarts, around the other students - he would have to figure out some way to lure Quirrell out of the castle -

But the grim young boy was still speaking. "Now, if the worst is true, then we know exactly where You-Know-Who is right now. And I don't think that's an opportunity we should pass up. Destroying his body didn't work last time, so I asked Hermione if she'd ever heard of anything that would destroy a soul, and she mentioned a method of executing criminals called the Dementor's Kiss..."
