“Impossible!” said Miss Wren, finally finding her voice.

“Wights can’t turn into birds!”

“That is true, as a general rule. But Alma is my sister, you see, and though I wasn’t fortunate enough to inherit any of her talents for manipulating time, I do share her most useless trait—the ability to turn into a vicious little bird of prey. I did a rather excellent job impersonating her, don’t you think?” And he took a little bow. “Now, may I trouble you for some pants? You have me at a disadvantage.”

His request was ignored. Meanwhile, my head was spinning. I remembered Miss Peregrine once mentioning that she’d had two brothers—I’d seen their photo, actually, when they were all in the care of Miss Avocet together. Then I flashed back to the days we’d spent with the bird we had believed was Miss Peregrine; all we’d gone though, everything we’d seen. The caged Miss Peregrine that Golan had thrown into the ocean—that had been the real one, while the one we “rescued” had been her brother. The cruel things Miss Peregrine had done recently made more sense now—that hadn’t been Miss Peregrine at all—but I was still left with a million questions.

“All that time,” I said. “Why did you stay a bird? Just to watch us?”

“While my lengthy observations of your childish bickering were incontrovertibly fascinating, I was quite hoping you could help me with a piece of unfinished business. When you killed my men in the countryside, I was impressed. You proved yourselves to be quite resourceful. Naturally, my men could’ve swept in and taken you at any point after that, but I thought it better to let you twist in the wind awhile and see if your ingenuity might not lead us to the one ymbryne who’s consistently managed to evade us.” With that, he turned to Miss Wren and grinned broadly. “Hello, Balenciaga. So good to see you again.”

Miss Wren moaned and fanned herself with her hand.

“You idiots, you cretins, you morons!” the clown shouted.

“You led them right to us!”

“And as a nice bonus,” said Caul, “we paid a visit to your menagerie, as well! My men came by not long after we left; the stuffed heads of that emu-raffe and boxer dog will look magnificent above my mantelpiece.”

“You monster!” Miss Wren screeched, and she fell back against the table, legs failing her.

“Oh, my bird!” exclaimed Bronwyn, her eyes wide. “Fiona and Claire!”

“You’ll see them again soon,” Caul said. “I’ve got them in safekeeping.”

It all began to make a terrible kind of sense. Caul knew he’d be welcomed into Miss Wren’s menagerie disguised as Miss Peregrine, and when she wasn’t at home to be kidnapped, he’d nudged us after her, toward London. In so many ways, we’d been manipulated from the very beginning—from the moment we chose to leave the island and I chose to go along. Even the tale he’d chosen for Bronwyn to read that first night in the forest, about the stone giant, had been a manipulation. He wanted us to find Miss Wren’s loop, and think that it was we who’d cracked its secret.

Those of us who weren’t reeling in horror frothed with anger. Several people were shouting that Caul should be killed, and were busily hunting for sharp objects to do the job with, while the few who’d kept their heads were trying to hold them back. All the while, Caul stood calmly, waiting for the furor to die down.

“If I may?” he said. “I wouldn’t entertain any ideas about killing me. You could, of course; no one can stop you. But it will go much easier for you if I am unharmed when my men arrive.” He pretended to check a nonexistent watch on his wrist. “Ah, yes,” he said, “they should be here now—yes, just about now—surrounding the building, covering every conceivable point of exit, including the roof. And might I add, there are fifty-six of them and they are armed positively to the teeth. Beyond the teeth. Have you ever seen what a mini-gun can do to a child-sized human body?” He looked directly at Olive and said, “It would turn you to cat’s meat, darling.”

“You’re bluffing!” said Enoch. “There’s no one out there!”

“I assure you, there is. They’ve been watching me closely since we left your depressing little island, and I gave my signal to them the moment Balenciaga revealed herself to us. That was over twelve hours ago—more than ample time to muster a fighting force.”

“Allow me to verify this,” said Miss Wren, and she left to go to the ymbryne meeting room, where the windows were obstructed from ice mostly from the outside, and a few had small telescope tunnels melted through them with mirror attachments that let us look down at the street below.

While we waited for her to return, the clown and the snake girl debated the best ways to torture Caul.

“I say we pull out his toenails first,” said the clown. “Then stick hot pokers in his eyes.”

“Where I come from,” the snake girl said, “the punishment for treason is being covered in honey, bound to an open boat, and floated out into a stagnant pond. The flies eat you alive.”

Caul stood cricking his neck from side to side and stretching his arms boredly. “Apologies,” he said. “Remaining a bird for so long tends to cramp the muscles.”

“You think we’re kidding?” said the clown.

“I think you’re amateurs,” said Caul. “If you found a few young bamboo shoots, I could show you something really wicked. As delightful as that would be, though, I do recommend you melt this ice, because it’ll save us all a world of trouble. I say this for your sake, out of genuine concern for your well-being.”

“Yeah, right,” said Emma. “Where was your concern when you were stealing those peculiars’ souls?”

“Ah, yes. Our three pioneers. Their sacrifice was necessary—all for the sake of progress, my dears. What we’re trying to do is advance the peculiar species, you see.”

“What a joke,” she said. “You’re nothing but power-hungry sadists!”

“I know you’re all quite sheltered and uneducated,” said Caul, “but did your ymbrynes not teach you about our people’s history? We peculiars used to be like gods roaming the earth! Giants—kings—the world’s rightful rulers! But over the centuries and millennia, we’ve suffered a terrible decline. We mixed with normals to such an extent that the purity of our peculiar blood has been diluted almost to nothing. And now look at us, how degraded we’ve become! We hide in these temporal backwaters, afraid of the very people we should be ruling, arrested in a state of perpetual childhood by this confederacy of busybodies—these women! Don’t you see how they’ve reduced us? Are you not ashamed? Do you have any idea of the power that’s rightfully ours? Don’t you feel the blood of giants in your veins?” He was losing his cool now, going red in the face. “We aren’t trying to eradicate peculiardom—we’re trying to save it!”

“Is that right?” said the clown, and then walked over to Caul and spat right in his face. “Well, you’ve got a twisted way of going at it.”

Caul wiped the spit away with the back of his hand. “I knew it would be pointless to reason with you. The ymbrynes have been feeding you lies and propaganda for a hundred years. Better, I think, to take your souls and start again fresh.”

Miss Wren returned. “He speaks the truth,” she said. “There must be fifty soldiers out there. All of them armed.”

“Oh, oh, oh,” moaned Bronwyn, “what are we to do?”

“Give up,” said Caul. “Go quietly.”

“It doesn’t matter how many of them there are,” Althea said.

“They’ll never be able to get through all my ice.”

The ice! I’d nearly forgotten. We were inside a fortress of ice!

“That’s right!” Caul said brightly. “She’s absolutely right, they can’t get in. So there’s a quick and painless way to do this, where you melt the ice voluntarily right now, or there’s the long, stubborn, slow, boring, sad way, which is called a siege, where for weeks and months my men stand guard outside while we stay in here, quietly starving to death. Maybe you’ll give up when you’re desperate and hungry enough. Or maybe you’ll start cannibalizing one another. Either way, if my men have to wait that long, they’ll torture every last one of you to death when they get in, which inevitably they will. And if we must go the slow, boring, sad route, then please, for the sake of the children, bring me some trousers.”

“Althea, fetch the man some damned trousers!” said Miss Wren. “But do not, under any circumstances, melt this ice!”

“Yes, ma’am,” replied Althea, and she went out.

“Now,” said Miss Wren, turning to Caul. “Here’s what we’ll do. You tell your men to allow us safe passage out of here, or we’ll kill you. If we have to do it, I assure you we will, and we’ll dump your stinking corpse out a hole in the ice a piece at a time. While I’m sure your men won’t like that much, we’ll have a very long time to devise our next move.”

Caul shrugged and said, “Oh, all right.”

“Really?” Miss Wren said.

“I thought I could scare you,” he said, “but you’re right, I’d rather not be killed. So take me to one of these holes in the ice and I’ll do as you’ve asked and shout down to my men.”

Althea came back in with some pants and threw them at Caul, and he put them on. Miss Wren appointed Bronwyn, the clown, and the folding man to be Caul’s guards, arming them with broken icicles. With their points aimed at his back, we proceeded into the hall. But as we were bottlenecking through the small, dark office that led to the ymbryne meeting room, everything went wrong. Someone tripped over a mattress and went down, and then I heard a scuffle break out in the dark. Emma lit a flame just in time to see Caul dragging Althea away from us by the hair. She kicked and flailed while Caul held a sharpened icicle to her throat and shouted, “Stay back or I drive this through her jugular!”

We followed Caul at a careful distance. He dragged Althea thrashing and kicking into the meeting hall, and then up onto the oval table, where he put her in a choke hold, the icicle held an inch from her eye, and shouted, “These are my demands!”

Before he could get any further, though, Althea slapped the icicle from his hand. It flew and landed point-down in the pages of the Map of Days. While his mouth was still forming an O of surprise, Althea’s hand latched onto the front of Caul’s pants, and the O broadened into a grimace of shock.

“Now!” Emma bellowed, and then she and I and Bronwyn rushed toward them through the wooden doors. But as we ran, the distance across that big room seemed to yawn, and in seconds the fight between Althea and Caul had taken another turn: Caul let go of Althea and fell to the table, his arms stretched and grasping for the icicle. Althea fell with him but did not let go—now had both hands wrapped around his thigh—and a coating of ice was spreading quickly across Caul’s lower half, paralyzing him from the waist down and freezing Althea’s hands to his leg. He got one finger around the icicle, and then his whole hand, and groaning with effort and pain, he wrenched it free from the Map and twisted his upper body until he had the point of it poised above Althea’s back. He screamed at her to stop and let him go and melt the ice or he’d plunge it into her.

We were just yards from them now, but Bronwyn caught Emma and me and held us back.

Caul screamed, “Stop! Stop this!” as his face contorted in pain, the ice racing up his chest and over his shoulders. In a few seconds, his arms and hands would be encased, too.

Althea didn’t stop.

And then Caul did it—he stabbed the icicle into her back. She tensed in shock, then groaned. Miss Wren ran toward them, screaming Althea’s name while the ice that had spread across most of Caul’s body began, very quickly, to recede. By the time Miss Wren reached them, he was nearly free of it. But then the ice everywhere was melting, too—fading and retracting just as quickly as Althea’s life was—the ice in the attic dripping and raining down through the ceiling just as Althea’s own blood ran down her body. She was in Miss Wren’s arms now, slack, going.

Bronwyn was on the table, Caul’s throat in one hand, his weapon crushed to snow in her other. We could hear the ice in floors below us melting, too, and then it was gone from the windows. We rushed to look out, and could see water flooding from lower windows into the street, where soldiers in gray urban camo were clinging to lampposts and fire hydrants to keep from being washed away by the icy waves.

Then we heard their boots stomping on the stairs below and coming down from the roof above, and moments later they burst in with their guns, shouting. Some of the men wore night-vision headsets and all of them bristled with weapons—compact machine guns, laser-sighted pistols, combat knives. It took three of them to pry Bronwyn away from Caul, who wheezed through his half-crushed windpipe, “Take them away, and don’t be gentle!”

Miss Wren was shouting, begging us to comply—“Do as they say or they’ll hurt you!”—but she wouldn’t let go of Althea’s body, so they made an example of her; they tore Althea away and kicked Miss Wren to the ground, and one of the soldiers fired his machine pistol into the ceiling just to scare us. When I saw Emma about to make a fireball with her hands, I grabbed her by the arm and begged her not to—“Don’t, please don’t, they’ll kill you!”—and then a rifle butt slammed into my chest and I fell gasping to the floor. One of the soldiers noosed my hands together behind me.
