Harry’s nose felt very hot, and then very cold. He raised a hand and felt gingerly. It seemed to be mended.
“Thanks a lot!”
“You’d better put that cloak back on, and we can walk up to the school,” said Tonks, still unsmiling. As Harry swung the cloak back over himself, she waved her wand; an immense silvery four-legged creature erupted from it and streaked off into the darkness.
“Was that a Patronus?” asked Harry, who had seen Dumbledore send messages like this.
“Yes, I’m sending word to the castle that I’ve got you or they’ll worry. Come on, we’d better not dawdle.”
They set off toward the lane that led to the school.
“How did you find me?”
“I noticed you hadn’t left the train and I knew you had that cloak. I thought you might be hiding for some reason. When I saw the blinds were drawn down on that compartment I thought I’d check.”
“But what are you doing here, anyway?” Harry asked.
“I’m stationed in Hogsmeade now, to give the school extra protection,” said Tonks.
“Is it just you who’s stationed up here, or—?”
“No, Proudfoot, Savage, and Dawlish are here too.”
“Dawlish, that Auror Dumbledore attacked last year?”
“That’s right.”
They trudged up the dark, deserted lane, following the freshly made carriage tracks. Harry looked sideways at Tonks under his cloak. Last year she had been inquisitive (to the point of being a little annoying at times), she had laughed easily, she had made jokes. Now she seemed older and much more serious and purposeful. Was this all the effect of what had happened at the Ministry? He reflected uncomfortably that Hermione would have suggested he say something consoling about Sirius to her, that it hadn’t been her fault at all, but he couldn’t bring himself to do it. He was far from blaming her for Sirius’s death; it was no more her fault than anyone else’s (and much less than his), but he did not like talking about Sirius if he could avoid it. And so they tramped on through the cold night in silence, Tonks’s long cloak whispering on the ground behind them.
Having always traveled there by carriage, Harry had never before appreciated just how far Hogwarts was from Hogsmeade Station. With great relief he finally saw the tall pillars on either side of the gates, each topped with a winged boar. He was cold, he was hungry and he was quite keen to leave this new, gloomy Tonks behind. But when he put out a hand to push open the gates, he found them chained shut.
“Alohomora!” he said confidently, pointing his wand at the padlock, but nothing happened.
“That won’t work on these,” said Tonks. “Dumbledore bewitched them himself.”
