"It would," Tonks agrees, "but in order for him to do that, there needs to be a plan, and Draco has to be informed about the plan – and I don’t see any way we can do that. The information he sends us is mostly numbers and coded locations, how many people are going to be where. It’s easy to do on a charmed Galleon. What you’re talking about would require reading him in on Horcruxes in general, which I’m not at all sure we should do, and then him having a plausible excuse to visit his aunt’s vault. Would he even have a way to destroy a Horcrux if he found one?"
