The moon was bright, but clouds scudding across it kept throwing them into darkness. Ahead, Harry could see the lighted windows of Hagrid’s hut. Then they heard a distant shout.
“Is that you, Filch? Hurry up, I want ter get started.”
Harry’s heart rose; if they were going to be working with Hagrid it wouldn’t be so bad. His relief must have showed in his face, because Filch said, “I suppose you think you’ll be enjoying yourself with that oaf? Well, think again, boy — it’s into the forest you’re going and I’m much mistaken if you’ll all come out in one piece.”
At this, Neville let out a little moan, and Malfoy stopped dead in his tracks.
“The forest?” he repeated, and he didn’t sound quite as cool as usual. “We can’t go in there at night — there’s all sorts of things in there — werewolves, I heard.”
Neville clutched the sleeve of Harry’s robe and made a choking noise.
“That’s your problem, isn’t it?” said Filch, his voice cracking with glee. “Should’ve thought of them werewolves before you got in trouble, shouldn’t you?”
Hagrid came striding toward them out of the dark, Fang at his heel. He was carrying his large crossbow, and a quiver of arrows hung over his shoulder.
“Abou’ time,” he said. “I bin waitin’ fer half an hour already. All right, Harry, Hermione?”
“I shouldn’t be too friendly to them, Hagrid,” said Filch coldly, “they’re here to be punished, after all.”
“That’s why yer late, is it?” said Hagrid, frowning at Filch. “Bin lecturin’ them, eh? ’Snot your place ter do that. Yeh’ve done yer bit, I’ll take over from here.”
“I’ll be back at dawn,” said Filch, “for what’s left of them,” he added nastily, and he turned and started back toward the castle, his lamp bobbing away in the darkness.
Malfoy now turned to Hagrid.
“I’m not going in that forest,” he said, and Harry was pleased to hear the note of panic in his voice.
“Yeh are if yeh want ter stay at Hogwarts,” said Hagrid fiercely. “Yeh’ve done wrong an’ now yeh’ve got ter pay fer it.”
“But this is servant stuff, it’s not for students to do. I thought we’d be copying lines or something, if my father knew I was doing this, he’d —”
“— tell yer that’s how it is at Hogwarts,” Hagrid growled. “Copyin’ lines! What good’s that ter anyone? Yeh’ll do summat useful or yeh’ll get out. If yeh think yer father’d rather you were expelled, then get back off ter the castle an’ pack. Go on!”
Malfoy didn’t move. He looked at Hagrid furiously, but then dropped his gaze.
“Right then,” said Hagrid, “now, listen carefully, ’cause it’s dangerous what we’re gonna do tonight, an’ I don’ want no one takin’ risks. Follow me over here a moment.”
He led them to the very edge of the forest. Holding his lamp up high, he pointed down a narrow, winding earth track that disappeared into the thick black trees. A light breeze lifted their hair as they looked into the forest.
“Look there,” said Hagrid, “see that stuff shinin’ on the ground? Silvery stuff? That’s unicorn blood. There’s a unicorn in there bin hurt badly by summat. This is the second time in a week. I found one dead last Wednesday. We’re gonna try an’ find the poor thing. We might have ter put it out of its misery.”
“And what if whatever hurt the unicorn finds us first?” said Malfoy, unable to keep the fear out of his voice.
“There’s nothin’ that lives in the forest that’ll hurt yeh if yer with me or Fang,” said Hagrid. “An’ keep ter the path. Right, now, we’re gonna split inter two parties an’ follow the trail in diff’rent directions. There’s blood all over the place, it must’ve bin staggerin’ around since last night at least.”
“I want Fang,” said Malfoy quickly, looking at Fang’s long teeth.
“All right, but I warn yeh, he’s a coward,” said Hagrid. “So me, Harry, an’ Hermione’ll go one way an’ Draco, Neville, an’ Fang’ll go the other. Now, if any of us finds the unicorn, we’ll send up green sparks, right? Get yer wands out an’ practice now — that’s it — an’ if anyone gets in trouble, send up red sparks, an’ we’ll all come an’ find yeh — so, be careful — let’s go.”
The forest was black and silent. A little way into it they reached a fork in the earth path, and Harry, Hermione, and Hagrid took the left path while Malfoy, Neville, and Fang took the right.
They walked in silence, their eyes on the ground. Every now and then a ray of moonlight through the branches above lit a spot of silver-blue blood on the fallen leaves.
Harry saw that Hagrid looked very worried.
“Could a werewolf be killing the unicorns?” Harry asked.
“Not fast enough,” said Hagrid. “It’s not easy ter catch a unicorn, they’re powerful magic creatures. I never knew one ter be hurt before.”
They walked past a mossy tree stump. Harry could hear running water; there must be a stream somewhere close by. There were still spots of unicorn blood here and there along the winding path.
“You all right, Hermione?” Hagrid whispered. “Don’ worry, it can’t’ve gone far if it’s this badly hurt, an’ then we’ll be able ter — GET BEHIND THAT TREE!”
Hagrid seized Harry and Hermione and hoisted them off the path behind a towering oak. He pulled out an arrow and fitted it into his crossbow, raising it, ready to fire. The three of them listened. Something was slithering over dead leaves nearby: it sounded like a cloak trailing along the ground. Hagrid was squinting up the dark path, but after a few seconds, the sound faded away.
“I knew it,” he murmured. “There’s summat in here that shouldn’ be.”
“A werewolf?” Harry suggested.
“That wasn’ no werewolf an’ it wasn’ no unicorn, neither,” said Hagrid grimly. “Right, follow me, but careful, now.”
They walked more slowly, ears straining for the faintest sound. Suddenly, in a clearing ahead, something definitely moved.
