Ron was tied between Hermione and Cho Chang. There was also a girl who looked no older than eight, whose clouds of silvery hair made Harry feel sure that she was Fleur Delacour’s sister. All four of them appeared to be in a very deep sleep. Their heads were lolling onto their shoulders, and fine streams of bubbles kept issuing from their mouths.

Harry sped toward the hostages, half expecting the merpeople to lower their spears and charge at him, but they did nothing. The ropes of weed tying the hostages to the statue were thick, slimy, and very strong. For a fleeting second he thought of the knife Sirius had bought him for Christmas—locked in his trunk in the castle a quarter of a mile away, no use to him whatsoever.

He looked around. Many of the merpeople surrounding them were carrying spears. He swam swiftly toward a seven-foot-tall merman with a long green beard and a choker of shark fangs and tried to mime a request to borrow the spear. The merman laughed and shook his head.

“We do not help,” he said in a harsh, croaky voice.

“Come ON!” Harry said fiercely (but only bubbles issued from his mouth), and he tried to pull the spear away from the merman, but the merman yanked it back, still shaking his head and laughing.

Harry swirled around, staring about. Something sharp . . . anything . . .

There were rocks littering the lake bottom. He dived and snatched up a particularly jagged one and returned to the statue. He began to hack at the ropes binding Ron, and after several minutes’ hard work, they broke apart. Ron floated, unconscious, a few inches above the lake bottom, drifting a little in the ebb of the water.

Harry looked around. There was no sign of any of the other champions. What were they playing at? Why didn’t they hurry up? He turned back to Hermione, raised the jagged rock, and began to hack at her bindings too—

At once, several pairs of strong gray hands seized him. Half a dozen mermen were pulling him away from Hermione, shaking their green-haired heads, and laughing.

“You take your own hostage,” one of them said to him. “Leave the others . . . ”

“No way!” said Harry furiously—but only two large bubbles came out.

“Your task is to retrieve your own friend . . . leave the others . . . ”

“She’s my friend too!” Harry yelled, gesturing toward Hermione, an enormous silver bubble emerging soundlessly from his lips. “And I don’t want them to die either!”
