"He started to removea" I took in a deep, shaking breath. Only in the presence of the Revered Speaker, or of his representative, did one put aside one's sandals. "The army isn't satisfied with Tizoctzin. It's only normal they'd want to find someone else to worship a that's hardly his fault." Even to me, the words rang as hollow as rotten wood.

"Ah, but he didn't try very hard to stop them, either."

I remembered what Teomitl had said, when they'd both tried to bow down to him. Now is neither the time nor the place.

Now, no. But later, perhaps a once Tizoc-tzin was overthrown, and Teomitl himself crowned Revered Speaker?

When I came back, I found Teomitl still sitting on his reed-matand Mihmatini gathering up Nezahual-tzin's feather headdress and cloak. "Feeling better?" I asked.

Teomitl grimaced. "Not really. And you, Acatl-tzin?"

Every muscle in my body felt stretched and pounded, like maize in the mortar, and without the cane, I wouldn't have been able to stand up. "I've been better." I didn't say anything about Nezahual-tzin's warning; I wasn't sure why. A desire not to worry him a or perhaps a sign that I believed Nezahual-tzin far more than I should have?

I would watch, and wait, and the accusation would prove itself groundless, another of Nezahual-tzin's little games. Yes. It had to be. Teomitl wasn't a fool. He had to know open rebellion would throw the Mexica Empire into more disarray than it could bear.

He had to. "Mihmatini?" I asked.

She paused on her way to the entrance. "Yes?"

"You haven't told me how it went, with the She-Snake. After the trial."

"Oh." She paused. "Nothing much. I complained and the SheSnake notified me I was acting irresponsibly. We both know who put him up to this." She snorted. "If you ask me, Tizoc-tzin still sees me as a young, inexperienced girl."

Did he? It was his loss, then. Both Teomitl and I had got over that stage long ago.

I was watching Teomitl's face as she spoke, and saw the hands clench and the shadow of jade imprint itself over the features. "My brother is a fool." There was something in his voice: a harshness that hadn't been there before, as if being so close to death had stripped away the last of the pretence.

"Teomitl," I started, but at this moment the entrance-curtain was wrenched open a by one of Mihmatini's priests. "My Lady Guardian..."

"What is it?"

"There is a delegation in the courtyard, asking to see you and the High Priest for the Dead."

The delegation was, as I had suspected, mostly priests from my order, Ichtaca at their head. "Acatl-tzin." He looked relieved to see me. "When we didn't see you come back..."

I shook my head, obscurely ashamed. "I haven't abandoned you. It's just been a a busy day."

"He almost died," Mihmatini said, fiercely. "What is it?"

Ichtaca took a deep breath. "You have to come to the palace, now."

My heart sank. What had happened now? "Why?"

It was Palli, the round-faced offering priest, who spoke up. "The sickness is no longer contained, Acatl-tzin. It'sa" he took a deep breath "it's got into one of the palace wings. There are dozens of dead people."

THIRTEEN.

Sickness in Our Midst The atmosphere in the palace was tense and fearful a even worse than four months before, when a star-demon had wreaked havoc in the courtyards, killing one councillor and carrying off the soul of a second. The first few courtyards we crossed seemed to be devoid of the She-Snake's black-clad guards, but as we went deeper a towards the affected wing a we saw more and more of them, and heard the growing clamour of the crowd.

"How bad is it?" I asked Ichtaca.

"Thirteen sick, two dead. And it's spreading." For once, he'd agreed to walk ahead of me, casting aside the etiquette which would have seen him defer to me as his superior. And a good thing: I was still weary and slow, limping through the courtyards with the help of Ceyaxochitl's cane, and of course I only had a vague idea of where we were going.

"And they don't know where it started?"

If Ichtaca had had less of a sense of decorum, he'd have thrown his hands up. "The priests of Huitzilpochtli are quite... competent."

"But not enough?" I guessed, shrewdly. They were Quenami's order, and Quenami had never had to handle a massive panic.

"You're assuming Quenami will be capable of something beyond court intrigue," Mihmatini said, curtly a she'd insisted on accompanying us, when it had become clear that the emergency concerned her as well.

"To be fair," Ichtaca said with a grimace, "I'm not sure we'd have handled it better. It's work for the clergy of Tlaloc."

Who inconveniently happened to be locked in cages, awaiting Tizoc-tzin's pleasure.

The courtyards we passed were all but deserted, the entrancecurtains closed with the finality of barricades. From time to time, a pale face would peek between the curtains a and withdraw just as fast, as if unable to meet our gaze.

Gradually, the noise grew: it was the priests of Huitzlipochtli arguing with burly warriors, trying to convince them they should stay inside, wait for the contagion to be ended.

"And when in the Fifth World do you think this is going to happen?" One of the warriors waved his macuahitl sword, threateningly; his companion laid a hand on his arm. "Let it go, Atl. You know priests are useless."

"I assure youa" the priest said in a quavering voice.

"Great work," Mihmatini muttered under her breath. I winced, but said nothing. Ichtaca likewise made no comment, but quickened his pace a forcing me to stay the same if I wanted to remain ahead of him.

There were more priests in the following courtyards, and the same total lack of mastery: they stood in doorways, arguing with irate warriors and noblemen a with mothers holding out wailing children, and old women who looked totally unfazed by any of their finery. As we neared the centre, it got worse and worse; the quarrels louder, the priests more numerous but equally ineffective, and the people milling outside, hoping to break the containment, becoming more and more dispersed.

And, in the last courtyard, there was a crowd a not densely packed, but at least a hundred people, mostly artisans, judging by their garb, and by the handful of feathers and precious stones scattered on the ground. From somewhere within the hubbub, I caught Quenami's raised voice: "You see, we have toa"

He didn't see. Like most artisans, they worked within the palace, but didn't sleep there. Their workshops were there a and, granted, their whole families had come with them, helping them glue feathers or mosaic beads, or sort out precious stones, but they certainly hadn't expected to be all but imprisoned in the palace.

Mihmatini was already pushing her way towards the centre, and Ichtaca and my priests followed in her wake, but the noise of the crowd was growing a a rolling wave of discontent that wouldn't be quelled by Quenami's words. It was going to burst.

Mihmatini had reached the centre. I caught angry words, presumably coming from one of the priests, and her own voice, raised to carry. "There is no cause for alarm..."

I was still lagging behind when it all broke down: one moment I was slowly making my way through a crowd of angry artisans, the next moment people were pressed against me, trying to hit me, to hit each other, anger palpable in the air. I couldn't see my priests, or Mihmatini, and the noise around me was only the wordless murmur of the crowd.

I tried to reach up with my one free hand, to slash my earlobes and whisper a prayer to Lord Death a which would have endowed me with the cold of the underworld, keeping the mob at bay, but they were too numerous, I couldn't...

Instead, I was all but carried by the crowd to the edge of the courtyard: it wasn't anger at the priests that drove them, but desire to leave the palace. I understood, but I couldn't not condone. For all we knew, several among them were already contaminated, carrying the sickness everywhere within the palace. They had to be stopped a and, indeed, the She-Snake's guards were already pulling up at the entrance to the courtyard, their uniforms a stark black against the adobe, their faces pale in the afternoon light a leeched of all colours, save the glint of their spears, the colours of their feather-shields.

The crowd in which I was caught wavered and came to a stop a and, for a bare moment, I dared to hope I might somehow slip away, turn back, and make my tottering way to Mihmatini and my priests a but then one artisan, more adventurous than one of his fellows, threw an adze at the leftmost guard.

The guard ducked, but the crowd was inflamed: the first ranks flung themselves at the guard, heedless of their spears. They fell back, cut, but there were always more artisans to take their place...

Buffeted here and there, I nevertheless managed to reach up with my free hand and, without a knife, rub at my earlobes, ignoring the growing pain until a sharper stab of pain told me I'd succeeded in removing the scabs from my previous offerings. The blood that stained my hands was only a few drops, but it would suffice.

"In the land of the fleshless In the region of mystery Where jade crumbles, where feathers become dust..."

Cold rose up, caught me in its embrace a gradually extinguishing every other feeling until it was all I could feel. The people on either side of me a two burly artisans weighing precious stones as if they were weapons a shrank back, and I used the opportunity to make my way out of the crowd, pointing the cane ahead of me like a weapon. I came to a rest under the row of pillars surrounding the courtyard. A few hostile gazes followed me: if I didn't move away, I'd be the next person they threw adzes at.

Where was Mihmatini?

A soft, dappled radiance came from the centre of the courtyard: the press of artisans had shrunk there, become almost a huddle. I caught a glimpse of Quenami's haughty face, and Mihmatini in hurried conversation with Ichtaca and two artisans. It didn't look as though they were fighting.

At the courtyard's entrance, the guards were putting up a valiant fight, but they would not last long and I couldn't see how we would prevent them from leaving at all: more carriers of the plague in the heart of the city, further deaths...

Southern Hummingbird strike me, I couldn't see a way out of this. If only I could make my way over to Mihmatini... I was about to move towards her when something brushed against me: the touch of some magic, like cold fingers lingering on my skin, sending chills into my heart. It might have been one of the artisans, but the spell was unerring, casting aside my protections as if they were nothing. Unless we had a sorcerer hidden among the artisans, it couldn't be any of them. I raised my gaze and, through the corner of one eye, I caught a glimpse of a man at the other courtyard entrance a the one that led deeper into the palace, where only a few frightened servants had lingered. He wore rags, but leant against one of the pillars with the casual, relaxed attitude of noblemen a and the profile. The lean, aristocratic face was achingly familiar.

It couldn't be...

Acamapichtli?

Calling through the din of the crowd would have been futile. Instead, I made my way further in a away from the pack tearing at the guards, the crowd becoming thinner and thinner as I retreated. I'd have broken into a run, if only I didn't feel so weak. Instead, I all but limped to the other end and by the time I reached the entrance, there was no one there.

I looked left and right, but even the servants had left. Had I imagined the whole thing? Acamapichtli was under arrest, like the rest of his clergy a kept in a cell where his powers would be weakened; kept under guard, so he couldn't plot against Tizoc-tzin (futile... Acamapichtli plotted as he breathed).

Just as I was about to head back into the courtyard, the magic came again: a weaker touch, skilfully drawing aside my protections a an invitation to step forward. I followed it into the next courtyard, and then into another, which was bare and deserted, the flowers in the earth wilted. The cane scraped against the ground, the echo of this the only sound within the courtyard.

Footsteps came from one of the buildings around the courtyard. I hobbled painstakingly towards it, but Acamapichtli was pulling the entrance-curtain open long before I finished crossing the courtyard.

"Well, fancy meeting you here." His face was creased in a sarcastic smile.

He looked much as he always had: his face lean and haughty, his eyes deep-set, his lips curved in sardonic joy. Save, of course, that he no longer wore the headdress of heron feathers that had marked him as the slave of his god, the loyal servant of the city a and that his cloak was of maguey fibres, more suitable for a commoner than for a High Priest. His hair, unbound, fell down to his feet, black and lanky, stiff with the blood of his offerings. Deprived of the black paint on his face, he looked curiously effeminate, the aggression all but smoothed out of his features.

"So it was you. How in the Fifth Worlda?"

He raised a hand. "Later. There isn't much time. Come in, will you?"

"You mean they'll be looking for you?"

Acamapichtli grimaced. "Of course. I used the chaos, but it won't last forever. Don't make me waste my time, Acatl."

"Are you telling me the truth?"

Acamapichtli frowned. "I'll swear it on Tlaloc, if that's what it takes. On the Provider, the Ruler of the Blessed Drowned, the Lord of the Sweet-Scented Marigold, He who holds the jars of rain."

My doubt must have shown on my face, for he added, with the same old impatience, "Don't be a fool. I have mocked you and schemed against you, but have you ever known me to lie to you?"

The worst thing was, I couldn't remember if he had. Unlike Tizoc-tzin, I didn't keep a tally of who had offended me, and when. "Not under oath," I admitted, grudgingly.

I stepped into the room, and Acamapichtli let the entrance-curtain fall. It appeared to be an artisan's workshop: fragments of feathers and precious stones were still spread out on reed mats, and a half-completed shield, showing the outline of a coyote in red feathers, lay in a corner, against the brazier.

I laid the cane down, and leant against the wall, trying to appear casual a in spite of the rapid beat of my heart. Acamapichtli watched me, smiling sardonically; I doubted he was much taken in by my pretence of calm.

"Fine," I said. "If you're here, you might as well tell me about this." I reached into the small bag I carried with me, and fished out the distorted black thing I'd taken out of Teomitl's body. s "Is thata?"

"Taken from the body of a sick man," I said, unwilling to admit Teomitl had been sick. "You said you only had a few hoursa"

"Yes, yes." Acamapichtli waved a dismissive hand. "But this is more important. Give me one of your blades, will you?" He gestured at his clothing with a sharp, joyless laugh. "I'm not quite as wellequipped as I should be."

"It's been dedicated to Mictlantecuhtli," I said, slowly. And the magic of Mictlantecuhtli Lord Death would be anathema to that of Tlaloc a but Acamapichtli shook his head. "It should do. I just need it to draw blood."

If, a year ago, someone had told me I would be standing in a deserted room helping the High Priest of Tlaloc safeguard us against an epidemic... I might have laughed, or railed, or done four hundred other things, but I wouldn't have believed it.

Acamapichtli laid the creature on the floor, with an almost reverent care. Muttering under his breath, he slashed his earlobes and the back of his left hand, and let the blood drip down onto the ground.

"By Your will, O, Our Lord May bounty and good fortune be unleashed May the sweet-scented marigold rattles shakes May the rattleboards of the mist clatter..."

Mist pooled out from the place the blood had struck the ground, spreading fast, as if someone had pierced a hole in the wall of a steam house. It climbed up, clinging to the back of Acamapichtli's hand where he had cut himself, and the air itself became tight, hard to breathe, tinged with the characteristic, marshy smell of Tlaloc's magic.

"With a sprinkle, with a few drops of dew Let us be blessed with fullness and abundance May it be in Your heart to grant, to give, to bring comfort..."

At length, Acamapichtli looked up. "It's what I thought," he said. He made a single, dismissive gesture with his hands a as if sending away an underling who had displeased a and the mist fell away, sinking back into the ground as if it had never been. It became easier to breathe once again.

"What you thought?" I asked.

He smiled a a thoroughly unpleasant expression. "The magic does look similar to that of Tlaloc, but it doesn't belong to Him. It's Chalchiuhtlicue's."

"That's not possible," I said, sharply. Chalchiuhtlicue, Jade Skirt; Tlaloc's wife, Teomitl's protector. Goddess of Lakes and Streams a patron of women in labour, She who washed away the sins of newborn children.

"Because you're the expert on the water gods?"

"No," I said. "But I'd thought..." My voice trailed off. "You said it was Tlaloc's magic earlier."
