I'll no doubt read any and all of these you choose to write because you're my safe place in the H/D world, but there's something about the description of Unscrupulous Practices that's really compelling. I've seen a few people make Draco an Auror to redeem his name or to try to please Harry or get Harry's attention, but none that have given him a more self-serving motivation independent of what Harry and broader wizarding society will think of him. As for Harry melting into the sunlight, I can't wait to see how you explain that.
