"Were we?" Ziani shook his head. "I'm sorry," he said, "I can't remember."
Valens clicked his tongue. "You were saying that a big double-action bellows was all right for relatively shallow shafts, but for deeper work there's some way of using fires to suck air down into the tunnels. Sounded a bit dubious to me, but you're the engineer." Ziani took a deep breath. "What's going to happen to him?"
"What do you think?" Valens laughed. "You Mezentines may be streets ahead of us in everything else, but when it comes to judicial murder, we've got you beat every time. You won't find any condemned traitors getting away from us by jumping out of windows or carving up sentries. Count yourself lucky on that score that you didn't have us to contend with. No, they'll probably take him round behind one of the big supply wagons and do it there. It's where the butchers go to slaughter chickens, out of sight of the horses so they don't spook. It's amazing, the way horses freak out if they see something getting killed; though not people, oddly enough, only other animals. Though we did have a few of the wagon horses go crazy during the battle; smashed up their traces and bolted, miserable bloody creatures. It makes you ask yourself: why can't anything in this world ever hold still?" He paused, then shrugged his shoulders. "It was justice, that's all. I can see why you probably don't like the look of it, you having had such a close call yourself. Can't blame you; but it's got to be done."
"What about the Duchess?" Ziani asked. "Will she understand?"
Valens scowled, then said: "No, of course not. I've screwed that up, for good. But that's no bad thing. It was a distraction; all very fine and splendid when there's nothing serious going on, but when you're facing the annihilation of your people, you need to keep a clear head. If we're going to get across the desert, I'll need to be able to concentrate. Hence the clearing up of odds and ends." He shifted suddenly in his seat, then became still again. "That Nennius is a competent man. Still a bit young, but he has the rare and valuable virtue of doing what he's told." He yawned; genuinely tired, as far as Ziani could judge. "Do you think I should've sent him back to the Mezentines?"
"No," Ziani said.
Valens nodded. "It did seem like a fair compromise," he said, "but I thought, what the hell, let's just for once do something properly, instead of fudging the issue just in case we've misjudged it. My father always used to say, never ever give anybody a second chance. I always used to think he was a vicious bastard. Well, he was, but I'm beginning to understand why. Didn't somebody say once that the tragedy of mankind is that as they get older, sons gradually turn into their fathers? Probably a young man, the one who said that. I wish I'd had the chance to know my father when I was a bit older. He died when I was at that rebellious stage, and so I've always been torn between hating and despising everything he stood for, and trying to be his deputy, so to speak, doing the things he'd have done if he'd lived. Of course, he'd never have gone to Civitas Eremiae; which rather puts me in my place, don't you think?"
Ziani stood up. "If that's everything you wanted to see me about…" he said.
Outside, nothing seemed out of the ordinary. They were carrying hay on pitchforks to feed the horses, or rolling barrels, or searching for strayed children, or arguing with the sentries about some camp regulation or other. Obviously Nennius had done a properly discreet job; not a good idea to spook the rest of the flock by slaughtering a duke where people could see. Well; the news would circulate quickly enough. Built into Ziani's calculations was the assumption that Orsea's death would be a popular move among the Vadani; they'd all sleep better at night knowing that the traitor who'd brought the Mezentines down on them was dead, and Valens would be respected for not allowing the malefactor's exalted rank to save him. He paused to remember Orsea as he'd first encountered him-wounded in the disastrous battle, confused, tearing himself apart with guilt, still able to find a little compassion for the misfortunes of a stranger. Well; like a true nobleman, he'd lived to serve. In death he'd been useful. By now, he was just a carcass, inedible meat. One more, among so very many.
"There you are." He looked round and saw Daurenja loping toward him like a big, friendly dog. "I've been looking for you, but nobody seemed to know where you'd got to."
Not now, Ziani thought. "I've been busy," he said. "The Duke…"
"Won't take a moment." Daurenja fell in beside him, matching his pace exactly. "I've been thinking," he said. "You remember I talked to you a while back, about this pet project of mine. The exploding sulfur compound, and making a tube to use it in."
"Oh, that." Ziani frowned. "I haven't given it any thought, I'm afraid."
"That's all right," Daurenja said magnanimously. "You've had other things on your mind. But I've been thinking about it-what you said, about forging the tube rather than casting it. Great idea, and I can see the sense in it, but there's a few small details I'd like your opinion on. For a start-"
"Not now," Ziani said.
"Oh, just while we're walking," Daurenja replied cheerfully. "I'm sure it's me being thick, and you can explain what I've been missing in just a few words. Let's see, now. You were talking about staves, like making a barrel; presumably you're thinking about butt-welding them around a mandrel. But-"
"You don't want to take any of that too seriously," Ziani said irritably. "I was just thinking aloud. On reflection, I'm fairly sure it wouldn't work."
"Oh, I don't agree. I think you've cracked it. But were you thinking about welding all the staves in turn, a separate heat for each one, or trying to do the whole lot in one heat? Only there's distortion to think about if you're doing them piecemeal, but if you're going for simultaneous, you'd need to rotate the mandrel, which'd mean-"
Ziani stopped. "Why don't you listen?" he said. "I'm not interested in helping you with this ridiculous idea of yours. I've heard about what happened to your last business partner." Daurenja pulled what he guessed was supposed to be an appeasing face, but he ignored it. "If I were you," he went on, "I'd clear out now, while you still can. Piss off back to the Cure Doce, or Lonazep. Or the Mezentines, if you really admire them so much-if you're Cure Doce by birth, that makes you a neutral, they've got no quarrel with your people. Go away, and leave me alone."
"I don't think so." Daurenja looked faintly disappointed, maybe a little hurt. "Thanks to you, I've made myself very useful here. They need me. I'm afraid you can't just chuck me out if and when you feel like it, I'm working directly for the Duke these days. Besides," he added, "things have changed rather a lot in the last half-hour, haven't they?"
"What do you mean?"
Daurenja sighed. "I happened to see my friend Major Nennius just now," he said. "I don't think he saw me; he was preoccupied, a job he was doing. Not," he added quickly, "that I blame you. Had to be done, I can see that quite clearly; you had no choice. But I don't think Duke Valens would be very happy if he knew about how it had come about, if you get my meaning."
It was that kind of fear that chills you to the bone; not the heart-stopping kind that forces all the breath out of you, or the immediate physical danger that loosens the bowels and the bladder. In spite of it, Ziani found he could keep quite calm. "I don't understand," he said.
"Of course you do," Daurenja said indulgently. "And I appreciate it's not something you feel like discussing, especially out here in the open where people might be eavesdropping. We'll have a nice long chat about it some time, when we're both of us not quite so busy. I will say this, though: you're a clever man. False modesty aside, I've always reckoned I'm quite smart, a cut above everybody else I've ever come across-you've got to believe that, haven't you, or how can you justify doing the difficult, nasty stuff? But I can see, compared to you I'm crude and ignorant. You could say, I am to you as the Vadani are to the Mezentines. Uncouth, you could call it. Unsophisticated." He smiled warmly. "I knew you were the right man for me to tag along with; I knew it when I first heard about you. A man after my own heart, I thought. I mean, look at what you've achieved, and practically nothing to work with. And look at you now. Leading the Vadani to join up with the Cure Hardy and change the entire world; and all so you can go home. Quite apart from the skill of it, the sheer scope of your vision is magnificent." He shook his head. "I know this sounds corny as hell, but I'm really proud to know you, Ziani Vaatzes. Today of all days; when it all started to come together, I mean." He shrugged. "Look," he went on, "I can tell you're not really in the mood for talking about lap-welds and expansion coefficients; we'll leave it for another time. I hope you don't mind me saying my piece, by the way. Only, my principle's always been, be open with people, tell them what you think. That's got to be the right way, hasn't it?"
