His heart thundered. “It would explain how they were able to come and go unnoticed.”

And if the old woman had been brought down there …

“How did they even get her to go? Without anyone noticing?”

He didn’t want to answer. The Valg could summon shadows if they wished. And hide within them. And those shadows could turn deadly in an instant.

Yrene slid to a stop in front of the main library desk, Nousha’s head snapping up. The marble was so smooth Yrene had to grapple at the edges of the desk to keep from falling.

“Have you seen Hafiza?” she blurted.

Nousha looked between them. Noted the sword he still had out.

“What is wrong.”

“Where are the tunnels?” Yrene demanded. “The ones they boarded up—where are they?”

Behind her, a storm-gray Baast Cat leaped up from its vigil by the hearth and sprinted into the library proper.

Nousha gazed at an ancient bell the size of a melon atop the desk. A hammer lay beside it.

Yrene slapped her hand on the hammer. “Don’t. It will alert them that—that we know.”

The woman’s brown skin seemed to go wan. “Head down to the bottom level. Walk straight to the wall. Cut left. Take that to the farthest wall—the very end. Where the stone is rough and unpolished. Cut right. You’ll see them.”

Yrene’s chest heaved, but she nodded, muttering the directions to herself. Chaol memorized them, planted them in his mind.

Nousha rose to her feet. “Shall I summon the guard?”

“Yes,” Chaol said. “But quietly. Send them after us. As fast as you can.”

Nousha’s hands shook as she folded them in front of her middle. “Those tunnels have been left untouched for a very long time. Be on your guard. Even we do not know what lies down there.”

Chaol debated mentioning the usefulness of cryptic warnings before plunging into battle, but simply entwined his fingers through Yrene’s and launched them down the hall.

61

Yrene counted every step. Not that it helped, but her brain just produced the numbers in an endless tally.

One, two, three … Forty.

Three hundred.

Four twenty-four.

Seven hundred twenty-one.

Down and down they went, scanning every shadow and aisle, every alcove and reading room and nook. Nothing.

Only acolytes quietly working, many packing up for the night. No Baast Cats—not one.

Eight hundred thirty.

One thousand three.

They hit the bottom of the library, the lights dimmer. Sleepier.

The shadows more alert. Yrene saw faces in all of them.

Chaol plunged ahead, sword like quicksilver as they followed Nousha’s directions.

The temperature dropped. The lights became fewer and farther between.

Leather books were replaced with crumbling scrolls. Scrolls replaced by carved tablets. Wooden shelves gave way to stone alcoves. The marble floor turned uncut. So did the walls.

“Here,” Chaol breathed, and drew her into a stop, his sword lifting.

The hall before them was lit by a sole candle. Left to burn on the ground.

And down it: four doors.

Three sealed with heavy stone, but the fourth … Open. The stone rolled aside. Another lone candle before it, illumining the darkness beyond.

A tunnel. Deeper than the Womb—deeper than any level of the Torre.

Chaol pointed to the rough dirt of the passage ahead. “Tracks. Two sets, side by side.”

Sure enough, the ground had been disturbed.

He whirled to her. “You stay here, I’ll—”

“No.” He weighed the word, her stance, as she added, “Together. We do this together.”

Chaol took another moment to consider, then nodded. Carefully, he led her along, showing her where to step to avoid any loud noises on loose bits of stone.

The candle beckoned by the open tunnel doorway. A beacon. An invitation.

The light danced along his blade as he angled it before the tunnel entrance.

Nothing but fallen blocks of stone and an endless dark passage greeted them.

Yrene breathed in through her nose, out through her mouth. Hafiza. Hafiza was in there. Either hurt or worse, and—

Chaol linked his hand with hers and led her into the dark.

They inched along in silence for untold minutes. Until the light from the sole candle faded behind them—and another appeared. Faintly, far off. As if around a distant corner.

As if someone was waiting.

Chaol knew it was a trap.

Knew the Healer on High had not been the target, but the bait. But if they arrived too late …

He would not let that happen.

They inched toward that second candle, the light as good as ringing the dinner bell.

But he moved forward nonetheless, Yrene keeping pace beside him.

The sole candle grew brighter.

Not a candle. A golden light from the passage beyond. Gilding the stone wall behind it.

Yrene tried to hurry, but he kept their pace slow. Quiet as death.

Though he had no doubt whoever it was already knew they were coming.

They reached the turn in the tunnel, and he studied the light on the far wall, trying to read for any shadows or disruptions. Only light.

He peered around the corner. Yrene did so, too.

Her breath snagged. He had seen some sights in the past year, but this …

It was a chamber, as enormous as the entire throne room in Rifthold’s palace, perhaps larger. The ceiling held aloft on carved pillars receding into the gloom, a set of stairs leading down from the tunnel onto the main floor. He knew why the light had been golden upon the walls.

For illuminated by the torches that burned throughout … Gold.

The wealth of an ancient empire filled the chamber. Chests and statues and trinkets of pure gold. Suits of armor. Swords.

And scattered amongst it all were sarcophagi. Built not from gold, but impenetrable stone.

A tomb—and a trove. And at the very back, rising up on a towering dais …

Yrene let out a small sound at the sight of the gagged and bound Healer on High seated on a golden throne. But it was the woman standing beside the healer, a knife resting on her round belly, that made Chaol’s blood go cold.

Duva. The khagan’s now-youngest daughter.

She smiled at them as they approached—and the expression was not human.

It was Valg.
