was so tall that she had to push the canopy of the trees apart as she stepped out of the forest, cracking and snapping branches. The wand-light only reached her chest, which was roughly about the same height as Grawp's head. Her head was merely a shadowed shape moving above the treetops, outlined against the starry sky. She moved slower than Grawp, ponderously, her great feet coming down to the ground like falling millstones, shaking leaves from the nearby trees with each step.
'So much for stealth,' Hardcastle commented, staring up at the monstrous figure.
'Harry, Titus, James, Zane, and Ted,' Hagrid called out very slowly, 'meet Prechka. Prechka, these are friends.'
Prechka bent down slightly so that her head hovered over Grawp's shoulder. She made a low, interrogative grunt that James thought actually rattled the windows in Hagrid's cottage. Harry raised his lit wand over his head and smiled. 'Prechka, Grawp, thank you both for coming and helping us. We won't keep you long, I hope. Hagrid has explained what we are asking you to do tonight, has he?'
Grawp gathered himself to speak. 'Harry look for sneaking man. Grawp and Prechka help.'
'Excellent,' Harry said, turning to address the group. 'Hagrid, you take Trife and get him on the scent from the path. See if he can pick up anything leading off the trail into the forest or around the lake. If so, send up a red signal. Ted, you'll be with me and Prechka in the forest. Zane, James, you'll both join Titus and Grawp searching the perimeter of the lake. We're searching for a back trail as much as we're looking for the intruder himself, so watch for broken branches, disturbed undergrowth and ground leaves, and anything human-related, such as bits of cloth, trash, papers, or anything of that nature. Everyone clear?'
'Who're we looking for, Harry?' Ted asked.
Harry was already approaching Prechka slowly. 'We'll know that when we find him, won't we?'
Zane, James, and Hardcastle climbed onto Grawp's back as the giant squatted down. James and Zane both clambered onto a shoulder, gripping Grawp's ragged shirt for support. Hardcastle, apparently oblivious to how ridiculous it might look, straddled the back of Grawp's neck like a kid being carried by his dad. He held his lit wand up and out, spreading a halo of light onto the ground around them, and then directed Grawp toward the lake. As they left, Harry and Ted were still working out the best method to get onto Prechka's shoulders.
'Do we need a ladder, you think?' Ted called.
'Get her to bend all the way over, with her hands on the ground,' Harry called, waving up to the she-giant, who had kneeled, but become distracted by Hagrid's garden. She pulled up a handful of pumpkins, roots and all, and began stuffing them into her mouth.
'That's right, that's right,' Hagrid called soothingly. 'Just lean over here a bit. There we go. Oh!'
There was a sharp wooden crunch as Prechka leaned on Hagrid's wagon, crushing it to kindling.
Hagrid patted the gigantic elbow, shaking his head. 'Oy, at least yeh can climb up now, Harry. Just use the wall there as a step. There yeh go.'
Prechka was being coaxed upright again, Harry and Ted perched on her shoulders, when Grawp entered the woods lining the west side of the lake and all view of the Hogwarts grounds vanished behind dense, stunted trees.
Grawp was surprisingly gentle, turning sideways and ducking to avoid branches that might knock his cargo off his back. James could feel the weight of Grawp's footsteps pressing into the ground far below, but experienced none of the shudder and thump he had expected to feel riding on a giant's back. Hardcastle directed Grawp quietly, being seated almost right next to the giant's ear. He led them in an orderly zigzag, approaching the lake, and then turning back into the thick of the wood again, slowly advancing around the perimeter. Their progress was slow and the motion of Grawp's walking began to rock James into sleepiness. He shook himself awake, studying the ground below for any of the signs his dad had described. In an attempt to keep himself awake, he explained to Hardcastle and Zane how he had seen the unidentified man on the Quidditch pitch. He told them about the camera, and described the other two times he'd seen the man on the grounds.
'You've seen this person three times, then?' Hardcastle asked, his voice a gravelly monotone.
'Yeah,' James nodded.
'But apart from your dad tonight, no one else has seen him at all?'
James felt rankled by that, but answered directly. 'No. Nobody.'
They were silent again for a while. James guessed that they had travelled approximately a third of the way around the perimeter. He saw glimpses of the castle looming over the lake whenever they neared its edge. The woods seemed annoyingly untouched and normal. Crickets buzzed and creaked, filling the night air with their strange chorus. Everywhere James looked, fireflies stitched the shadows, going about their nocturnal business. There was no sign that anyone had ever been through this wood, much less anyone recently.
'Stop, Grawp,' Hardcastle said suddenly, his voice tense. Grawp stopped obediently and stood still. His massive head turned slightly as he looked around. James peered around Grawp's enormous, dirty ear, trying to see what Hardcastle was looking at or listening for. Half a minute crept by. James knew not to speak. Then, in the near distance, there was a harsh scurrying sound. Something scrambled, unseen, through the fallen leaves and stopped again. A branch creaked, as if it were being stepped on. James' heart was suddenly pounding. Still, neither Grawp nor Hardcastle moved. James saw Hardcastle turn his head slightly, trying to pinpoint the direction of the sound.
It came again, nearer this time, but still unseen. It was ahead of them, behind a low rise on the woods side of their path. James couldn't help thinking that there was something distinctly inhuman about the scurrying sound. It was, somehow, too busy. The hair at the base of his neck prickled.
Hardcastle tapped the back of Grawp's head lightly and pointed toward the ground, reaching so Grawp could see his hand. James felt the giant lower, and was surprised again at the slow grace of the motion. The leaves underfoot crackled only slightly as Grawp put his hands on the ground. Hardcastle slid silently off Grawp's back. His eyes were locked on the low rise ahead.
'Stay with--'
He was interrupted by the noise of scrambling movement. It was much closer this time, and now James saw the motion of it. Dead leaves scattered into the air as a large, shadowy form scuttled over the rise, moving with horrible speed. It darted in and out of the trunks of the trees, crashing through bushes. It seemed to have far too many legs, and there was a strange bluish glow emanating from its front. It flickered wildly as the thing moved. Hardcastle leaped in front of Grawp as the thing approached. He flicked his wand with the practiced economy of a
