“The Ninth?”

Gideon’s heart was still ricocheting around her chest. She raised her shoulders in an expression that the brethren of the Locked Tomb would have recognised immediately as the precursor of Gideon about to do something particularly daft, but Corona took it as acceptance, and said mock-indulgently to her cav: “Well, then, my dear, go off and make yourself happy.”

He beamed as though he had just been bought a new pair of shoes. Gideon thought: Shit.

The Cohort cavalier, Dyas, was saying: “Your Highness. The adept shouldn’t officiate for their cavalier.”

“Oh, pff! Surely just this once can’t harm, Lieutenant.”

“You can’t call yourself a disinterested arbitrator, Princess,” Magnus was saying.

“Nonsense: I’m harder on him than anyone else. To the touch; call!”

In a very short space of time she was standing face to face with another cavalier, and there was a juddering in her ears that she recognised as the beating of her own heart. The glass of her knuckle-knives felt black and cold and silky all the way through a layer of robe and her shirt, and her tongue felt thick in her mouth. She hadn’t been this overstimulated since that one time when training had consisted of Crux, a repeating crossbow, and two skeletons with machetes. The Third’s main-gauche dagger was as gorgeously wrought as his hair: chased silver and Imperial violet, the arms of the hilt curved and hugging inward in a way that tugged on her memory but did not grasp the right file. The blade was thin and bright and flared at the top. She was so busy looking at it that she barely heard Naberius say:

“Naberius the Third.”

And very, very quietly, just for her:

“Ninth cavs are necro suitcases. Who’re you?”

It was good that she had already practised how to be quiet, because the traditional Nav response would have been one of any number of pieces of crude backchat. She resented the contempt with which his mouth rounded over Ninth; she resented suitcases; she resented his hair. But Coronabeth was singing out, “I call for Gideon the Ninth!” and they were marking five paces—six—seven.

She had only a moment to size Naberius up. He was about an inch shorter than her, with a frame that had been whipped within an inch of its life into perfectly sculpted muscle. He was narrow shouldered with long, long arms, and she was beginning to believe that he was not simply a douchebag who used lip balm, but a douchebag who used lip balm and had a very long reach. He stood perfectly: more perfectly even than her teacher, who had partially fused her spine with standing to attention. His rapier was a froth of silver wire and tracery at the loop of the hilt, and the blade shone notchless, perfect as the line made from his shoulder to its tip: her answering stance felt slouchy and half-assed, and the black knuckle-knives brutish, unsurgical. The hard moue of his mouth told her that he was used to making people feel that way, but also that he definitely used lip balm. Her heart sped up: slowed: renewed, arrhythmic with anticipation.

“Begin!” called Corona.

In the first ten seconds, Gideon had known that the fight with the Fifth House was hers to lose. It took her twenty seconds to come to a very important discovery about the House of the Third: it valued cleanliness. Each twitch of the sword was a masterpiece of technique. He fought like clockwork: inevitable, bloodless, perfect, with absolute economy of movement. The first time the black sword of the Ninth flicked into action, the line of his rapier slicing hers to the side—a simple semicircle arc with the blade, bored, contemptuous, exact—would have brought an expert to tears. His advance and retreat were like lines from a manual, fed directly into his feet.

Stop blocking every blow, her brain told her. Her arm ignored her brain, and sparks glittered as Naberius’s sword clanked against the obsidian glass of her defending knuckle-knives; the force of the blow reverberated up Gideon’s arm and shuddered into her spine. Her sword sang forward in what she knew to be a perfect thrust, aimed true and hard at his side; she heard an oily shnk!, and then another blow quaked its way into her elbow and up to the base of her skull. The blade she had taken for a dagger had separated into three, trapping hers neatly: a trident knife, which was so hopelessly obvious that she probably had to offer to save time and kick her own ass for him. Naberius smiled at her, blandly.

It was the most irritating fight she’d ever had. He wasn’t as fast as she was, but he wasn’t wearing robes, and anyway he didn’t have to be as fast as she was. He just had to keep her at arm’s length, and he was a master at it. This to the touch nonsense was pissing her off. If she had been wielding her longsword she would have simply smashed through him like a brick through a windowpane. But she had a needle in one hand and a handful of black glass in the other, and had to skip and hop around like he was wielding poison; and he had been a cavalier probably since the day he was born. At some points he could stand there completely still, completely bored, his sword held in perfect form as though he were doing dressage. The light beat down on her robes and her head. She couldn’t believe she was being held at bay by someone who had eaten every cavalier manual and chewed dutifully twenty-five times.

Naberius toyed with her languidly—he had a trick where his sword licked out like a cat’s claw, immediate, before pulling back again with a measured half step—and he kept her at sword’s length, never letting her enter his space. He kept up his litany of parry; quick attack for space; pressure the sword with the offhand until she was sick to death of it.

Gideon ran her rapier down the length of his—lightless black on silver—with a shrill squeal, but he circled it deftly down and away. She thrust again, high, and found that the upper breadth of her blade was caught neatly within the fork of that goddamned trident knife: he used the leverage to push her down.… down … and she found that his rapier was sliding forward, over her arm, through the tuck of her elbow. Aiglamene had taught her to anticipate a death blow. She flinched to the side immediately, letting it press tight against her, swearing mentally all the way: in a real fight he’d be able to slice a hot ribbon over her chest and shoulder, but couldn’t kill her either way. And he couldn’t touch her with the point, just the edge. She was still in the duel.

But then he did something perfect. It was probably recorded in some shitty Seventh-style swordplay book as TWO CROWS DRINKING WATER or THE BOY STRANGLES THE GOOSE. He pivoted her sword downward with his three-bladed knife, jerked the wrist of his rapier-hand forward, and flicked the black blade of the Ninth from her grip. It clattered to the worn-out flagstones and was still. Jeannemary gulped off a yelp in the background. Her heart trickled like prayer beads sliding down a string.

Naberius stepped out of his lunge and smiled that irritating smile again.

“You cut too much,” he said.

He did not smile when Gideon unwound her sword-arm from his rapier in a swift wheel of movement, ducked forward, and punched him in the solar plexus. The breath wheezed from his lungs like he was an open airlock. Naberius crumpled backward, and she kicked her robes aside to touch one booted foot to the place beneath his knee: he staggered, spat, and fell. She dropped for her sword and backpedalled for space, as he thrashed like a fallen animal trying to rise. Gideon fell into stance, raised her sword, and let it come to rest at his collarbone.

“Match to the Third,” said Coronabeth, which startled her.
