The disturbances did not abate, however. In the days that followed scarcely ten minutes would pass without his hearing Some sound 9f occupancy. The Prince of Darkness was here, Gregorius could have no doubt of it, but he was keeping to the shadows. Gregorius was content to play along. It was the Devil's party, after all. His to play whatever game he chose.

But during the long and often lonely months that followed, Gregorius wearied of this hide-and-seek and began to demand that Satan show himself. His voice rang unanswered down the deserted corridors, however, until his throat was bruised with shouting. Thereafter he went about his searches stealthily, hoping to catch his tenant unawares. But the Apostate Angel always flitted away before Gregorius could step within sight of him.

They would play a waiting game, it seemed, he and Satan, chasing each other's tails through ice and fire and ice again. Gregorius told himself to be patient. The Devil had come, hadn't he? Wasn't that his fingerprint on the door handle? His turd on the stairs? Sooner or later the Fiend would show his face, and Gregorius would spit on it.

THEworld outside went on its way, and Gregorius was consigned to the company of other recluses who had been ruined by wealth. His Folly, as it was known, was not entirely without visitors, however. There were a few who had loved him too much to forget him-a few, also, who had profited by him and hoped to turn his madness to their further profit-who dared the gates of the New Hell. These visitors made the journey without announcing their intentions, fearing the disapproval of their friends. The investigations into their subsequent disappearance never reached as far as North Africa.

ANDin his folly Gregorius still chased the Serpent, and the Serpent still eluded him, leaving only more and more terrible signs of his occupany as the months went by.

ITwas the wife of one of the missing visitors who finally discovered the truth and alerted the authorities. Gregorius's Folly was put under surveillance, and finally-some three years after its completion-a quartet of officers braved the threshold.

Without maintenance the Folly had begun to deteriorate badly. The lights had failed on many of the levels, its walls had cooled, its pitch pits solidified. But as the officers advanced through the gloomy vaults in search of Gregorius they came upon ample evidence that despite its decrepit condition the New Hell was in good working order. There were bodies in the ovens, their faces wide and black. There were human remains seated and strung up in many of the rooms, gouged and pricked and slit to death.

Their terror grew with every door they pressed open, every new abomination their fevered eyes fell upon.

Two of the four who crossed the threshold never reached the chamber at its center. Terror overtook them on their way and they fled, only to be waylaid in some choked passageway and added to the hundreds who had perished in the Folly since Satan had taken residence.

Of the pair who finally unearthed the perpetrator, only one had courage enough to tell his story, though the scenes he faced there in the Folly's heart were almost too terrible to bear relating.

There was no sign of Satan, of course. There was only Gregorius. The master builder, finding no one to inhabit the house he had sweated over, had occupied it himself He had with him a few disciples whom he'd mustered over the years. They, like him, seemed unremarkable creatures. But there was not a torture device in the building they had not made thorough and merciless use of.

Gregorius did not resist his arrest. Indeed he seemed pleased to have a platform from which to boast of his butcheries. Then, and later at his trial, he spoke freely of his ambition and his appetite; and of how much more blood he would spill if they would only set him free to do so. Enough to drown all belief and its delusions, he swore. And still he would not be satisfied. For God was rotting in paradise, and Satan in the abyss, and who was to stop him?

He was much reviled during the trial, and later in the asylum where, under some suspicious circumstances, he died barely two months later. The Vatican expunged all report of him from its records. The seminaries founded in his unholy name were dissolved.

But there were those, even among the cardinals, who could not put his unrepentant malice out of their heads, and-in the privacy of their doubt-wondered if he had not succeeded in his strategy. If, in giving up all hope of angels-fallen or otherwise-he had not become one himself.

Or all that earth could bear of such phenomena.

THE BURNING man propelled himself down the steps of the Hume Laboratories as the police car-summoned, he presumed, by the alarm either Welles or Dance had set off upstairs-appeared at the gate and swung up the driveway As he ran from the door the car screeched up to the steps and discharged its human cargo. He waited in the shadows, too exhausted by terror to run any farther, certain that they would see him. But they disappeared through the swing doors without so much as a glance toward his torment. Am I on fire at all? he wondered. Was this horrifying spectacle-his flesh baptized with a polished flame that seared but failed to consume-simply a hallucination, for his eyes and his eyes only? If so, perhaps all that he had suffered up in the laboratory had also been delirium. Perhaps he had not truly committed the crimes he had fled from, the heat in his flesh licking him into ecstasies.

He looked down his body. His exposed skin still crawled with livid dots of fire, but one by one they were being extinguished. He was going out, he realized, like a neglected bonfire. The sensations that had suffused him-so intense and so demanding that they had been as like pain as pleasure-were finally deserting his nerve endings, leaving a numbness for which he was grateful. His body, now appearing from beneath the veil of fire, was in a sorry condition. His skin was a panic-map of scratches, his clothes torn to shreds, his hands sticky with coagulating blood; blood, he knew, that was not his own. There was no avoiding the bitter truth. He had done all he had imagined doing. Even now the officers would be staring down at his atrocious handiwork.

He crept away from his niche beside the door and down the driveway, keeping a lookout for the return of the two policemen. Neither reappeared. Tile street beyond the gate was deserted. He started to run. He had managed only a few paces when the alarm in the building behind him was abruptly cut off. For several seconds his ears rang in sympathy with the silenced bell. Then, eerily, he began to hear the sound of heat-the surreptitious murmuring of embers-distant enough that he didn't panic, yet close as his heartbeat.

He limped on to put as much distance as he could between him and his felonies before they' were discovered. But however fast he ran, the heat went with him, safe in some backwater of his gut, threatening with every desperate step he took to ignite him afresh.

IT took Dooley several seconds to identify the cacophony he was hearing from the upper floor now that McBride had hushed the alarm bell. It was the high-pitched chattering of monkeys, and it came from one of the many rooms down the corridor to his right.

"Virgil," he called down the stairwell. "Get up here."

Not waiting for his partner to join him, Dooley headed off toward the source of the din. Halfway along the corridor the smell of static and new carpeting gave way to a more pungent combination: urine, disinfectant and rotting fruit. Dooley slowed his advance. He didn't like the smell any more than he liked the hysteria in the babble of monkey voices. But McBride was slow in answering his call, and after a short hesitation, Dooley's curiosity got the better of his disquiet. Hand on truncheon he approached the open door and stepped in. His appearance sparked off another wave of frenzy from the animals, a dozen or so rhesus monkeys. They threw themselves around in their cages, somersaulting, screeching and berating the wire mesh. Their excitement was infectious. Dooley could feel the sweat begin to squeeze from his pores.
