No, it's a logical choice, honestly. Hydra's the secret keeper, isn't she? We'll need to lift that, I reckon. One of the nice things about Hogwarts is that it's public but fairly defensible.

We'll need a second Polyjuice detector in the main entrance, too. I'd like to leave the prototype here for Septima.

But the Manor doesn't have anti-Apparation, does it? That's something to consider. We don't want your Aunt Bella popping into the west drawing room for tea, do we?
