“Harry, this piece of vermin is the reason you have no parents,” Black snarled. “This cringing bit of filth would have seen you die too, without turning a hair. You heard him. His own stinking skin meant more to him than your whole family.”

“I know,” Harry panted. “We’ll take him up to the castle. We’ll hand him over to the dementors . . . He can go to Azkaban . . . but don’t kill him.”

“Harry!” gasped Pettigrew, and he flung his arms around Harry’s knees. “You—thank you—it’s more than I deserve—thank you—”

“Get off me,” Harry spat, throwing Pettigrew’s hands off him in disgust. “I’m not doing this for you. I’m doing it because—I don’t reckon my dad would’ve wanted them to become killers—just for you.”

No one moved or made a sound except Pettigrew, whose breath was coming in wheezes as he clutched his chest. Black and Lupin were looking at each other. Then, with one movement, they lowered their wands.

“You’re the only person who has the right to decide, Harry,” said Black. “But think . . . think what he did . . . ”

“He can go to Azkaban,” Harry repeated. “If anyone deserves that place, he does . . . ”

Pettigrew was still wheezing behind him.

“Very well,” said Lupin. “Stand aside, Harry.”

Harry hesitated.

“I’m going to tie him up,” said Lupin. “That’s all, I swear.”

Harry stepped out of the way. Thin cords shot from Lupin’s wand this time, and next moment, Pettigrew was wriggling on the floor, bound and gagged.

“But if you transform, Peter,” growled Black, his own wand pointing at Pettigrew too, “we will kill you. You agree, Harry?”

Harry looked down at the pitiful figure on the floor and nodded so that Pettigrew could see him.

“Right,” said Lupin, suddenly businesslike. “Ron, I can’t mend bones nearly as well as Madam Pomfrey, so I think it’s best if we just strap your leg up until we can get you to the hospital wing.”

He hurried over to Ron, bent down, tapped Ron’s leg with his wand, and muttered, “Ferula.” Bandages spun up Ron’s leg, strapping it tightly to a splint. Lupin helped him to his feet; Ron put his weight gingerly on the leg and didn’t wince.

“That’s better,” he said. “Thanks.”

“What about Professor Snape?” said Hermione in a small voice, looking down at Snape’s prone figure.

“There’s nothing seriously wrong with him,” said Lupin, bending over Snape and checking his pulse. “You were just a little—overenthusiastic. Still out cold. Er—perhaps it will be best if we don’t revive him until we’re safely back in the castle. We can take him like this . . . ”
