It was just like the night when Trelawney had been sacked. Students were standing all around the walls in a great ring (some of them, Hermione noticed, covered in a substance that looked very like Stinksap); teachers and ghosts were also in the crowd. Prominent among the onlookers were members of the Inquisitorial Squad, who were all looking exceptionally pleased with themselves, and Peeves, who was bobbing overhead, gazed down at Fred and George Weasley who stood in the middle of the floor with the unmistakeable look of two people who had just been cornered.
