“I felt weird,” said Ron, shifting his shoulders uncomfortably. “Like I’d never be cheerful again . . . ”

Ginny, who was huddled in her corner looking nearly as bad as Harry felt, gave a small sob; Hermione went over and put a comforting arm around her.

“But didn’t any of you—fall off your seats?” said Harry awkwardly.

“No,” said Ron, looking anxiously at Harry again. “Ginny was shaking like mad, though . . . ”

Harry didn’t understand. He felt weak and shivery, as though he were recovering from a bad bout of flu; he also felt the beginnings of shame. Why had he gone to pieces like that, when no one else had?

Professor Lupin had come back. He paused as he entered, looked around, and said, with a small smile, “I haven’t poisoned that chocolate, you know . . . ”

Harry took a bite and to his great surprise felt warmth spread suddenly to the tips of his fingers and toes.

“We’ll be at Hogwarts in ten minutes,” said Professor Lupin. “Are you all right, Harry?”

Harry didn’t ask how Professor Lupin knew his name.

“Fine,” he muttered, embarrassed.

They didn’t talk much during the remainder of the journey. At long last, the train stopped at Hogsmeade station, and there was a great scramble to get outside; owls hooted, cats meowed, and Neville’s pet toad croaked loudly from under his hat. It was freezing on the tiny platform; rain was driving down in icy sheets.

“Firs’ years this way!” called a familiar voice. Harry, Ron, and Hermione turned and saw the gigantic outline of Hagrid at the other end of the platform, beckoning the terrified-looking new students forward for their traditional journey across the lake.

“All righ,’ you three?” Hagrid yelled over the heads of the crowd. They waved at him, but had no chance to speak to him because the mass of people around them was shunting them away along the platform. Harry, Ron, and Hermione followed the rest of the school along the platform and out onto a rough mud track, where at least a hundred stagecoaches awaited the remaining students, each pulled, Harry could only assume, by an invisible horse, because when they climbed inside and shut the door, the coach set off all by itself, bumping and swaying in procession.

The coach smelled faintly of mold and straw. Harry felt better since the chocolate, but still weak. Ron and Hermione kept looking at him sideways, as though frightened he might collapse again.

As the carriage trundled toward a pair of magnificent wrought iron gates, flanked with stone columns topped with winged boars, Harry saw two more towering, hooded dementors, standing guard on either side. A wave of cold sickness threatened to engulf him again; he leaned back into the lumpy seat and closed his eyes until they had passed the gates. The carriage picked up speed on the long, sloping drive up to the castle; Hermione was leaning out of the tiny window, watching the many turrets and towers draw nearer. At last, the carriage swayed to a halt, and Hermione and Ron got out.
