As soon as Hermione and Colin had disappeared, he dashed back into the main aisle, conjuring a loud explosion to catch the Death Eaters' attention.
"Get him!" Lucius bellowed.
"What about the others?" one of the other Death Eaters asked.
"Don't worry about them. Potter's the only one we need."
Harry smiled with satisfaction as all of the Death Eaters that were still standing set off after him. He raced down the main aisle, casting shield charms in quick succession. He noted that his pursuers weren't using any dangerous spells, a sure sign that they still thought he had the orb in his possession.
So far, everything was going well. Time to start the next phase of his plan.
He veered to the right without warning and ran up the nearest row. He kept going until he was about halfway down, then turned around sharply and cast several stunning charms. He hadn't even had the time to take proper aim, but the narrow aisles which had conspired against them earlier were now working in his favor.
The Death Eaters had nowhere to run. Three of their numbers fell, but Lucius, Bellatrix and two others continued after him.
He made it to the end of the aisle, then immediately started up the next row. He prepared to attack again, but this time, Bellatrix was ready. She yanked one of her fellow Death Eaters in front of her as a shield, casting an incarcerous spell in his direction. He was in the midst of casting another stunning charm, so he wasn't able to block it.
Thick ropes wrapped around him like rapidly-growing vines. He lost his balance and toppled over, his wand clattering to the ground. He twisted desperately towards it, but Bellatrix got there first.
"Well, that's too bad, Potter. It looks like your little game is over." She smiled triumphantly as she pointed her wand at him. "Accio prophecy!"
Nothing happened, and the smile slid off her face. She turned to Lucius. "He doesn't have it."
The elder Malfoy stepped forward, his aristocratic features stony. "Where is it, Potter?"
"Like I'd ever tell you," Harry spat.
"Crucio!" Blinding agony consumed him, blocking out everything else. He screamed and writhed on the floor, feeling as if his insides were being ripped out.
"You forget, Potter," Bellatrix seethed, "that we don't have to play nice anymore. You should be on your knees begging for mercy."
"She's right, Potter," Lucius said imperiously. "Tell us where the prophecy is, and I'll consider sparing your life."
"Oh, gee, thanks a lot for the generous offer," he quipped, earning him another cruciatus curse.
He panted heavily as the pain finally let up, sweat streaming down his face and neck. He wasn't sure how many more of those he could take.
"There's no need for you to have to go through that again, Potter," Lucius said, his voice icy. "Just tell us where it is."
He glared up at his captors with every ounce of strength he could muster. "No."
He braced himself as Bellatrix raised her wand and cried, "Crucio!" but suddenly he felt himself being lifted by the collar of his robe and pulled out of harm's way.
A familiar dark-cloaked figure had come to stand beside him. With a flick of his wand, the ropes binding Harry evaporated. His face was mostly hidden in the shadow of his hood, but there was no mistaking the smirk on Draco Malfoy's face.
"What was that about not needing my help again, Potter?"
