“Well, I can certainly smell him this time,” Celaena said between panting breaths. They’d reached the site in little less than three hours, guessing by the sun. That was faster and longer than she’d ever run, thanks to the Fae form she’d been training in.

“This body has been rotting ­here longer than the demi-­Fae from three days ago.”

She bit back her retort. There had been another demi-­Fae body found, and he hadn’t let her go see it, instead forcing her to practice all day while he flew to the site. But this morning, he’d taken one look at the fire smoldering in her eyes and relented.

Celaena stepped carefully on the pine carpet, scanning for any signs of a fight or of the attacker. The ground was churned up, and despite the rushing stream, the flies ­were buzzing near what appeared to be a heap of clothing peeking from behind a small boulder.

Rowan swore, low and viciously, even lifting his forearm to cover his nose and mouth as he examined the husk that remained, the demi-­Fae male’s face twisted in horror. Celaena might done the same, except . . . except—

That second smell was ­here, too. Not as strong as it had been at the first site, but it lingered. She shoved back against the memory that wanted to rise in response to the smell, the memory that had overwhelmed her that day in the barrow-­field.

“It has our attention and it knows it,” she said. “It’s targeting demi-­Fae—either to send a message, or because they . . . taste good. But—” She pictured the map Rowan kept in his room, detailing the wide area where the corpses had been found, and winced. “What if there’s more than one?” Rowan looked back at her, brows high. She didn’t say anything ­else until she had moved to where he stood by the body, careful not to disturb any clues. Her stomach lurched and bile stung the back of her throat, but she clamped down on the horror with a wall of ice that even her fire could not melt. “You’re old as hell,” she said. “You must have considered that ­we’re dealing with a few of them, given how vast the territory is. What if the one we saw in the barrows ­wasn’t even the creature responsible for these bodies?”

He narrowed his eyes, but conceded a nod. She studied the hollowed-­out face, the torn clothes.

Torn clothes, what looked like small cuts along the palms—as if he’d dug in his fingernails. The others had barely been touched, but this . . .

“Rowan.” She waved away flies. “Rowan, tell me you see what I’m seeing.”

Another vicious curse. He crouched, using the tip of a dagger to push back a bit of clothing torn at the collar. “This male—”

“Fought. He fought back against it. None of the others did, according to the reports.”

The stench of the corpse was nearly enough to bring her to her knees. But she squatted by the decaying hand and forearm, shriveled and wasted from the inside out. She held out a hand for Rowan’s dagger, still possessing none of her own. He hesitated as she looked up at him.

Only for the afternoon, he seemed to growl as he pressed the hilt into her open palm.

She yanked down the dagger. I know, I know. I ­haven’t earned my weapons back yet. Don’t get your feathers ruffled.

She turned back to the husk, cutting off their wordless conversation and getting a snarl in response. Butting heads with Rowan was the least of her concerns, even if it had become one of her favorite activities.

There was something so familiar about doing this, she thought as she carefully, as gently and respectfully as she could, ran the tip of the dagger under the male’s cracked and filthy nails, then smeared the contents on the back of her own hand. Dirt and black . . . black . . .

“What the hell is that?” Rowan demanded, kneeling beside her, sniffing her outstretched hand. He jerked back, snarling. “That’s not dirt.”

No, it ­wasn’t. It was blacker than night, and reeked just as badly as it had the first time she’d smelled it, in the catacombs beneath the library, an obsidian, oily pool of blood. Slightly different from that other, horrific smell that loitered around this place, but similar. So similar to—

“This isn’t possible,” she said, jolting to her feet. “This—­this—this—” She paced, if only to keep from shaking. “I’m wrong. I have to be wrong.”

There had been so many cells in that forgotten dungeon beneath the library, beneath the king’s Wyrdstone clock tower. The creature she’d encountered there had possessed a human heart. It had been left, she’d suspected, because of some defect. What if . . . what if the perfected ones had been moved elsewhere? What if they ­were now . . . ready?

“Tell me,” Rowan growled, the words barely understandable as he seemed to struggle to rein in the killing edge he rode in response to the threat lurking somewhere in these woods.

She lifted her hand to rub her eyes, but realized what was on her fingers and went to wipe them on her shirt. Only to recall that she was wearing nothing but the soft white band around her br**sts, and that she was cold to her very bones. She rushed to the nearby stream to scrub off the dried black blood, hating even that the trace of it would be in the water, in the world, and quickly, quietly told Rowan of the creature in the library, the Wyrdkeys, and the information Maeve held hostage regarding how to destroy that power. Power that was being used by the king to make things—­and targeting people with magic in their blood to be their hosts.

A warm breeze wrapped around her, heating her bones and blood, steadying her. “How did it get ­here?” Rowan asked, his features now set with icy calm.

“I don’t know. I hope I’m wrong. But that smell—­I’ll never forget that smell as long as I live. Like it had rotted from the inside out, its very essence ruined.”

“But it retained some cognitive abilities. And what­ever this is, it must have them, too, if it’s dumping the bodies.”

She tried to swallow—­twice—but her mouth was dry. “Demi-­Fae . . . they would make perfect hosts, with so many of them able to use magic and no one in Wendlyn or Doranelle caring if they live or die. But these corpses—­if he wanted to kidnap them, why kill them?”

“Unless they ­weren’t compatible,” Rowan said. “And if they ­weren’t compatible, then what better use for them than to drain them dry?”

“But what’s the point of leaving the bodies where we can find them? To drum up fear?”
