We left the fractured planet behind, braving flares and gravity storms as we made a dash for the outer system. Forty minutes after leaving that place, rear-aligned sensors could find no trace of the 'wound', as if it had collapsed, or had never been there to begin with.

  How the saruthi came and went I had no idea, and Aemos was little help. We had seen no sign of other vessels or other points of egress from the planet's crust.

  'Do they live within the planet?' I asked Aemos as we stood at an observation platform, looking back at the retreating star through glare-dimmed ports.

  'I fancy not. Their technologies are beyond my ken, but I feel that they might have arrived on the plateau through those archways from another world, into a place they had built for the meeting.'

  Such a concept defied my imaginings. Aemos was suggesting interstellar teleportation.

  Outside the system, there had been little trace of the heretical fleet. As far as Maxilla was able to tell from drive and warp wakes, the three ships, no doubt bearing Locke and Dazzo, had rejoined their attentive flotilla and moved away almost at once into the immaterium.

  Other warp indicators informed us that the taskforce was approaching, no more than two days away. We dropped grav-anchor, saw to our wounds, and waited.

  Thirty weeks before, as we departed Damask, I had sent my request for assistance to Gudrun via Lowink astropathically. I had outlined as much of the situation as possible, providing what detail and conjecture I could, and had hoped the Lord Militant would send a military expedition to support me. I did not demand, as the likes of Commodus Voke were wont to do. I was sure the urgency and importance of my communique would speak for itself.

  Eleven ships loomed out of the empyrean before us in battle formation: six Imperial frigates running out in the van, fighter wings riding out ahead of them in formation. Behind this spearhead of warships came the battleships Vulpecula and Saint Scythus, each three times the size of the frigates, each a bristling ogre of a vessel. To the rear was an ominous trio of cruisers, black ships of the Imperial Inquisition. This was no military expedition. This was an inquisitorial taskforce.

  We exchanged hails, identified ourselves and were escorted into the fleet pack by an honour guard of thunderhawks. Shuttles transferred our wounded, including the still unconscious Fischig and the prisoner Malahite, to medicae faculties aboard the Saint Scythus. An hour later, at the request of Admiral Spatian, I also crossed by shuttle to the battleship. They were awaiting my report.

  My left arm bound and tightly slung in a surgical brace, I wore a suit of black and my button-sleeved leather coat, my rosette pinned at my throat. Aemos, in sober green robes, accompanied me.

  In the echoing vault of the Saint Scythus's docking bay, Procurator Olm Madorthene and a detail of navy stormtroopers waited to greet us.

  Madorthene wore the impressive white dress uniform in which I had first seen him, and the men's blue armour was rich with gold braid and ceremonial decoration.

  Madorthene greeted me with a salute and we strode as a group towards the elevators that would carry us up into the command levels of the ship.

  'How goes the uprising?' I asked.

  'Well enough, inquisitor. We understand the Lord Militant has declared the Helican Schism over and quashed, though pacification wars are still raging across Thracian.'

  'Losses?'

  'Considerable. Mainly to the population and materials of the world affected, though some fleet and guard units have taken a beating. Lord Glaw's treason has cost the Imperium dear.'

  'Lord Glaw's treason has cost him his life. His body rots on a nameless world in the system behind us.'

  He nodded. 'Your master will be pleased.'

  'My master?'

  Lord Inquisitor Phlebas Alessandro Rorken sat in a marble throne at the far end of a chapel-like audience hall two decks beneath the main bridge of the Saint Scythus. I had met him twice before, and felt no more confident now for those experiences. He wore simple robes of crimson over black clothing and gloves, and no other decoration except for a gold signet ring of office on one knuckle. The austere simplicity of his garb seemed to accentuate his authority. His noble skull was shaved except for a forked goatee. His eyes, deep set and wise, glittered with intelligence.

  Around him was his entourage. Ten inquisitorial novices of interrogator rank or below, upheld banners, sacred flamer weapons, caskets of scrolls and slates, gleaming tools of torture on red satin cushions, or open hymnals. Flanking them were four bodyguards in red cloaks with double-handed broadswords held stiffly upright before their faces. Their armour was ornate, and the full visors had been fashioned and painted into the likenesses of four apostolic saints: Olios, ferido, Manezzer and Kadmon. The masks were flat-eyed and expressionless and almost naive, lifted exactly from representations on illuminated manuscripts of old. A huddle of dark-robed savants waited nearby, and a dozen cherub servitors in the form of podgy three-year-olds with golden locks and the spiteful faces of gargoyles circled around, scolding and mocking, on grav-assisted golden wings.

  'Approach, Eisenhorn/ Lord Rorken said, his soft voice carrying down the chamber effortlessly. Approach all/

  At his words, other figures emerged from anterooms along the sides of the hall, and took their seats to either hand. One was Admiral Spatian, an ancient, skeletal giant in white dress uniform, attended by several of his senior staff. The others were inquisitors. Titus Endor, in his maroon coat, unescorted save for a hunched female savant. He cast me an encouraging

  nod as I passed by. Commodus Voke, wizened and shuffling, helped onto his seat by a tall man in black. The man's head was bald and hairless apart from a few sickly clumps. His scalp, neck and face were livid with scar-tissue from injuries and surgery. It was Heldane. His encounter with the carnodon had not improved his looks. Like Endor, Voke nodded to me, but there was no friendship in it.

  Next to him, Inquisitor Schongard, stocky and squat, the black metal mask obscuring everything but his raddled eyes. He took his seat and was flanked by two lean, supple females, members of some death-cult by the look of them, both nearly naked save for extensive body art, barbed hoods and harnesses strung with blades.

  Opposite Schongard sat Konrad Molitor, an ultra-radical member of the ordos I had little love or respect for. Molitor was a fit, athletic man dressed from head to toe in a tight weave-armour bodyglove of yellow and black check with a polished silver cuirass strapped around his torso. His black hair was close-trimmed and tonsured and he affected the air of a warrior monk from the First Crusade. Behind him stood three robed and hooded acolytes, one carrying Molitor's ornate powersword, another a silver chalice and paten, and the third a reliquary box and a smoking censer. Molitor's pupils were bright yellow and his gaze never wavered from me.

  Last to take his seat, at Lord Rorken's right hand, was a giant in black power armour, a Space Marine of the Deathwatch chapter, the dedicated unit of the Ordo Xenos. The Deathwatch was one of the Chambers Militant, Marine chapters founded exclusively for the Inquisition, obscure and secret even by the standards of the blessed Adeptus Astartes. At my approach, the warrior removed his helmet and set it on his armoured knee, revealing a slab-jawed, pale face and cropped grey hair. His thin mouth was curled in a frown.

  Servitors brought a seat for me, and I took my place facing the Lord Inquisitor. Aemos stood at my side, silent for once.

  We have read your preliminary report, Brother Eisenhorn. Quite a tale it is. Of great moment.' Lord Rorken savoured the last word. 'You pursued Glaw's heretic fleet to this Emperor-forsaken outer world, certain that they planned to trade with a xenos breed. That trade, you stated, was for an item whose very nature would threaten the safety and sanctity of our society.'

  'I reported correctly, lord brother.'

  "We have known you always to be earnest and truthful, brother. We did not doubt your words. After all, are we not here in... unusual force?'

  He gestured around and there was some laughter, most of it forced, most of
it from Voke and Molitor.

  And what was this item?'

  The aliens possessed a single copy of a profane and forbidden work we know as the Necroteuch.'

  The reaction was immediate. Voices rose all around, in surprise, alarm or disbelief. I heard Voke, Molitor and Schongard all calling out questions

  and scorn. The assembled retainers, novices and acolytes around us whispered or gabbled furiously. The cherubs wailed and fluttered into hiding behind Lord Rorken's throne. Rorken himself studied me dubiously. I saw that even the grim Space Marine looked questioningly at the inquisitor.

  Lord Rorken raised his hand and the hubbub died away.

  'Is that confirmed, Brother Eisenhorn?'

  'Lord, it is. I saw it with my own eyes and felt its evil. It was the Necroteuch. As far as I have learned, the xenos breed - known as the saruthi -came upon a lost copy thousands of years ago, and through recently established lines of communication with the Glaw cabal, agreed to exchange it for certain artefacts of their own culture.'

  'Preposterous!' spat Commodus Voke. 'The Necroteuch is a myth, and a wretched one at that! These twisted alien filth have fabricated this as a lure for the gullible heretics!'

  I looked over at Voke and repeated, 'I saw it with my own eyes and felt its evil. It was the Necroteuch.'

  Admiral Spatian looked up at Lord Rorken. This thing, this book - is it so valuable that these heretics would throw the entire sub-sector into schism to cover their attempts to retrieve it?'

  'It is priceless!' cut in Molitor from across the chamber. 'Beyond worth! If the legends of it are even fractionally true, it contains lore surpassing our understanding! They would not think twice of burning worlds to get it, or of sacrificing their entire resources to acquire the power it would bring them.'

  'It has always been plain/ Endor said softly, 'that the stakes in this matter have been astonishingly high. Though I am shocked by Brother Gregor's news, I am not surprised. Only an icon as potent as the Necroteuch could have set this bloodshed in motion.'

  'But the Necroteuch! Such a thing!' Schongard hissed.

  'Were they successful, Inquisitor Eisenhorn?' the Space Marine asked suddenly, staring directly at me.

  'No, brother-captain, they were not. The effort was desperate and close ran, but my force was able to spoil their contact with the xenos saruthi. The aliens were driven off, and most of the heretics' advance guard, including Lord Glaw and a blasphemous child of the Emperor allied to his cause, were slain.'

  'I read of this Mandragore in your report/ said the Marine. 'His presence was fundamental in the decision for my unit to accompany this force/

  The Emperor's Children, Terra damn their souls, clearly wanted the book for themselves. They had sent Mandragore to assist Glaw in its recovery. That beings such as they took it seriously confirms the truth of my story, I believe/

  The noble Marine nodded. And Mandragore is dead, you say?'

  'I killed him myself/

  The Deathwatch warrior sat back slightly, his brows rising gently in surprise.

  'Some heretics escaped your purge?' Schongard asked.

  Two key conspirators, brother. The trader, Gorgone Locke, who I believe was instrumental in forging the original contact between the saruthi and Glaw's cabal. And an ecclesiarch named Dazzo, who 1 would see as the spiritual force behind their enterprise. They fled from the fight, rejoined the waiting elements of their fleet, and left this system.'

  'Destination?' asked Spatian.

  'It is still being plotted, admiral/

  'And how many ships? That bastard traitor Estrum ran with fifteen/

  'He lost at least two frigates in that star system. A non-standard merchant ship that I believe belongs to Locke is with them/

  'Have they taken to their heels and run defeated, or have they some further agenda?' Lord Rorken asked.

  'I have further research to make before I can answer that, lord/

  Spatian stood and looked towards the Lord Inquisitor. 'Even if they're running, we can't permit them to escape. They must be hounded down and annihilated. Permission to retask the battle-pack and prepare to pursue/

  'Permission granted, admiral/

  Then Molitor spoke up. 'No one has asked the most important question of our heroic Brother Eisenhorn/ he said, stressing the word 'heroic' in a way that did not flatter. 'What happened to the Necroteuch?'

  I turned to face him. 'I did what any of us would have done, Brother Molitor. I burned it/

  Uproar followed. Molitor was on his feet, accusing me of nothing short of heresy at the top of his reedy voice. Schongard raised his own serpentine tones in support of the accusations, while Endor and Voke shouted them down. The retinues howled and bickered across the floor. Both the Deathwatch captain and I remained seated and silent.

  Lord Rorken rose. 'Enough!' He turned to the glowering Molitor. 'State your objection, Brother Molitor, quickly and simply/

  Molitor nodded, and licked his lips, his yellow eyes darting around the room. 'Eisenhorn must suffer our sternest censure for this act of vandalism! The Necroteuch may be a foul and proscribed work, but we are the Inquisition, lord. By what right did he simply destroy it? Such a thing should have been sequestered and brought before our most learned savants for study! To obliterate it out of hand robs us of knowledge, of wisdom, of secrets unimaginable! The contents of the Necroteuch might have given us insight into the archenemy of mankind, incalculable insight! How might it have strengthened us and armed us for the ceaseless fight? Eisenhorn has disgraced the very heart of our sacred Inquisition!'

  'Brother Schongard?'

  'My lord, I agree. It was a desperate and rash action by Eisenhorn. Carefully handled, the Necroteuch would have provided us with all measure of advantageous knowledge. Its arcane secrets would have been weapons

  against the foe. I may applaud his rigorous efforts in thwarting Glaw and his conspirators, but this erasure of occult lore earns only my opprobrium/

  'Brother Voke? What s-' Lord Rorken began, but I cut him off.

  'Is this a court, my lord? Am I on trial?'

  'No, brother, you are not. But the magnitude of your actions must be analysed and considered. Brother Voke?'

  Voke rose. 'Eisenhorn was right. The Necroteuch was an abomination. It would have been heresy to permit its continued existence!'

  'Brother Endor?'

  Titus did not rise. He turned in his seat and looked down the hall at Konrad Molitor. 'Gregor Eisenhorn has my full support. From your moaning, Molitor, I wonder what kind of man I am listening to. A radical, certainly. An inquisitor? I have my doubts/

  Molitor leapt up again, raging. 'You knave! You whoreson bastard knave! How dare you?'

  Very easily/ replied Endor, leaning back and folding his arms. And you, Schongard, you are no better. Shame on you! What secrets did you both think we could learn, except perhaps how to pollute our minds and boil away our sanity? The Necroteuch has been forbidden since before our foundation. We need not know what's in it to accept that prohibition! All we need is the precious knowledge that it should be destroyed, unread, on sight. Tell me, do you need to actually contract Uhlren's Pox yourself to know that it is fatal?'

  Lord Rorken smiled at this. He glanced at the Space Marine. 'Brother-Captain Cynewolf?'

  The captain made a modest shrug. 'I command kill-teams charged with the extermination of aliens, mutants and heretics, lord. The ethics of scholarship and book-learning I leave to the savants. For whatever it's worth, though, I would have burned it without a second thought/

  There was a long silence. Sometimes I was almost glad no one could tell when I was smiling.

  Lord Rorken sat back. 'The objections of my brothers are noted. I myself commend Eisenhorn. Given the extremity of his situation, he made the best decision/

  Thank you, my lord/

  'Let us retire now and consider this matter. I want to hear proposals for our next course of action in four hours/

  'What now?' Titus Endor asked as we sa
t in his private suite aboard the Saint Scyihus. A female servitor brought us glasses of vintage amasec, matured in nalwood casks.

  'The remnants must be purged/ I said. 'Dazzo and the rest of the heretic fleet. They may have been cheated of their prize, and they may be running now. Perhaps they'll run for years. But they have the resources

  of a battlegroup at their disposal, and the will to use it. I will recommend we hunt them down and finish this sorry matter once and for all/

  Aemos entered the chamber, made a respectful nod to Endor, and handed me a data-slate.

  The admiral's astronavigators have finished plotting the course of the heretic fleet. It matches the estimations Maxilla has just sent me/

  I scanned the data. 'Do you have a chart, Titus?'

  He nodded and engaged the functions of a glass-topped cogitator unit. The surface glowed, and he entered the reference codes from the slate.

  'So... they're not running back into Imperial space. No surprise. Nor out to the lawless distances of the Halo Stars/

  'Their course takes them here: 56-Izar. Ten weeks away/

  'In saruthi territory/

  'Right in the heart of saruthi territory/

  Lord Inquisitor Rorken nodded gravely. 'As you say, brother, this business may be less finished than we thought/

  They cannot hope to count the saruthi as allies, or believe they would give them safe haven. The entente between Glaw's forces and the xenos breed was fragile and tenuous to say the least, and what peace existed between them was rained by the violence. Dazzo must have some other reason to head there/

  Lord Rorken paced the floor of his state chamber, brooding, toying with the signet ring of office on his gloved finger. His flock of cherubs roosted uneasily along the backs of armchairs and couches around the room. Twitching their gargoyle heads from one side to another, they watched me keenly as I stood waiting for a reply. 'My imagination runs wild, Eisen-horn/ he said at last.
