There was one thing in her favour tonight. Ron had left all the candles burning, so the cavernous room was brightly lit. She scanned it. If she were a Weasel – Weasley, she corrected herself scrupulously – where would she hide important documents? She had to bear in mind that Ron, while probably not quite as stupid as the Slytherins made him out to be, was no Hermione Granger. His hiding place was unlikely to be especially complex.
