He dived again, and Cho, thinking he’d seen the Snitch, tried to follow; Harry pulled out of the dive very sharply; she hurtled downward; he rose fast as a bullet once more, and then saw it, for the third time—the Snitch was glittering way above the field at the Ravenclaw end.

He accelerated; so, many feet below, did Cho. He was winning, gaining on the Snitch with every second—then—

“Oh!” screamed Cho, pointing.

Distracted, Harry looked down.

Three dementors, three tall, black, hooded dementors, were looking up at him.

He didn’t stop to think. Plunging a hand down the neck of his robes, he whipped out his wand and roared, “Expecto patronum!”

Something silver-white, something enormous, erupted from the end of his wand. He knew it had shot directly at the dementors but didn’t pause to watch; his mind still miraculously clear, he looked ahead—he was nearly there. He stretched out the hand still grasping his wand and just managed to close his fingers over the small, struggling Snitch.

Madam Hooch’s whistle sounded. Harry turned around in midair and saw six scarlet blurs bearing down on him; next moment, the whole team was hugging him so hard he was nearly pulled off his broom. Down below he could hear the roars of the Gryffindors in the crowd.

“That’s my boy!” Wood kept yelling. Alicia, Angelina, and Katie had all kissed Harry; Fred had him in a grip so tight Harry felt as though his head would come off. In complete disarray, the team managed to make its way back to the ground. Harry got off his broom and looked up to see a gaggle of Gryffindor supporters sprinting onto the field, Ron in the lead. Before he knew it, he had been engulfed by the cheering crowd.

“Yes!” Ron yelled, yanking Harry’s arm into the air. “Yes! Yes!”

“Well done, Harry!” said Percy, looking delighted. “Ten Galleons to me! Must find Penelope, excuse me—”

“Good for you, Harry!” roared Seamus Finnigan.

“Ruddy brilliant!” boomed Hagrid over the heads of the milling Gryffindors.

“That was quite some Patronus,” said a voice in Harry’s ear.

Harry turned around to see Professor Lupin, who looked both shaken and pleased.

“The dementors didn’t affect me at all!” Harry said excitedly. “I didn’t feel a thing!”

“That would be because they—er—weren’t dementors,” said Professor Lupin. “Come and see—”

He led Harry out of the crowd until they were able to see the edge of the field.

“You gave Mr. Malfoy quite a fright,” said Lupin.

Harry stared. Lying in a crumpled heap on the ground were Malfoy, Crabbe, Goyle, and Marcus Flint, the Slytherin team Captain, all struggling to remove themselves from long, black, hooded robes. It looked as though Malfoy had been standing on Goyle’s shoulders. Standing over them, with an expression of the utmost fury on her face, was Professor McGonagall.
