Neville brought it to her that afternoon, and from the front of the envelope it was clear who it had been sent from. He had not inspected it, as he should have done, but he had no way of knowing that. Pansy had not mentioned such a rule to him before she left, as it was so rare for Hermione to receive post. The magnitude of such a sudden letter passed him like a subtle breeze. Not even Draco had enforced this rule much during all these years, being the only one who had his post taken to his study every day. Hermione simply never got letters or anything of the sort, and it had been a fact for so long by this point—a fact that Pansy used to their advantage. Doubly so, since the wards around the manor recognized the trace of her magical signature on the letter, and raised no alarm.
