But he said he served at Buckingham. It's impossible for him to attack or harm Voldemort directly, but I can understand how an elf could twist logic to the point where he could attack Harry, believing that Harry is not really related to his master.

Yeah, they can be as tricky as goblins.

Still. That's disturbing, to say the least. We know who's after Harry, now, but what good does it do us? Have to think on that. I'm not sure it's a good idea to enlist one elf against another, either, Allie. Or how to protect Harry against a foe who can come and go as he pleases.

Meanwhile, about the Chamber - well, I thought I knew every nook and cranny of that castle, but I've never heard of the chamber, except as a bedtime tale my parents used to use to scare us. James, Peter, Moony and I certainly never found anything like an entrance to the lair of a giant beast bent on destruction. It's got to be someone using the legend to his own ends. Who has a vested interest in seeing Hogwarts becomes pureblood only?
