"He's been gone for two full days now," Sirius said, pacing in nervous circles across the floor of their brand-new living room. "How long does it take to deliver a bloody letter?"

"We don't know if that was his whole mission," Lily said placatingly from one of the sofas. Sirius had been a nervous wreck ever since Remus left for Dornoch, and he was only getting worse the longer he was gone. All of them were nervous, really—they had no idea what could be taking him so long. Peter had bitten his nails almost down to their quicks. He couldn't imagine what he would do if Dumbledore ever sent him on a solo mission—he wouldn't do that, would he? Lily, seeing him shiver, wrapped an arm around him and pulled him closer to her.

"Look at this," James said, coming down the stairs with a letter in hand. "I just got this from an owl. It's for Remus, from his dad."

"What?" Sirius stopped his pacing and whirled around to face James. "Why would it be delivered here?"

"It must mean the owl couldn't get to Remus for some reason." James threw the letter down onto the sofa and pulled at his hair. "Owls always know how to find the right people; Lexie's never misdelivered something before. This can't be good."

"Well, Remus does live here," Lily pointed out. "Maybe the letter was just delivered for him in advance."

"Lils, I love you, but you're not going to stop us from going mental today. Moony's been gone way too long—and tonight's the full moon. He's got to be back before the full moon."

"I know," Lily murmured. "I—I'm sure he will be." If he wasn't, Peter thought, if he couldn't get himself locked up somewhere in time, Remus was likely to do something he'd never be able to forgive himself for. Peter shivered once again at the thought.

Ding-dong. The four of them jumped at the sound of their doorbell echoing through the house; no one had rung it since they moved in. The only people who knew where they lived were other members of the Order.

"Remus?" Sirius asked hopefully.

James shook his head. "He would've done the knock."

Lily helped Peter off of the sofa, and together the four of them cautiously approached the front door, James peering through the peephole and cursing at whatever he saw on the other side. "This isn't going to be good," he murmured.

"Who is it?" Peter asked nervously.

In response, James pulled open the door to reveal their porch crowded with witches and wizards: Frank and Alice Longbottom, Dorcas Meadowes, Marlene McKinnon, Harriet Favreau, and Neville Lewis. They all wore solemn, dark expressions.

"What?" James demanded of them.

Marlene stepped forward. "The Order's just received another tip-off from Mundungus," she said. "Remus has been captured by the werewolves and brought to Fenrir Greyback. Fenrir's holding him prisoner in his camp."

Peter felt like all the blood was draining form his veins. No. Not Fenrir—anyone but Fenrir Greyback, the werewolf who had destroyed Remus's entire life.

"We have to break him out of there," Frank said gravely. "Now."
