¡°Oh yes,¡± said Dumbledore coldly. ¡°But I'm afraid no Dementor will cross the threshold of this castle while I am Headmaster.¡±
¡°So how about it?¡± Ron said to Harry as though there had been no interruption. ¡°Come on, last time we went you didn't see anything. You haven't even been inside Zonko's yet!¡±
The team cheered madly. Harry let the Snitch go again, gave it a minute's head start, then tore after it, weaving in and out of the others; he spotted it lurking near Katie Bell's knee, looped her easily, and caught it again.
¡°You know what this means?¡± Black said abruptly to Harry as they made their slow progress along the tunnel. ¡°Turning Pettigrew in?¡±
She continued in this vein for some time, until Wood said, ¡°Er ¡ª Madam Hooch? Is it okay if Harry has the Firebolt back? We need to practice¡¡±
