And so he took pains, though without making definite suggestion, to place himself in the way of this woman and her nephew--only to find that his hints were disregarded. They left him alone, if they did not actually avoid him. Moreover, he rarely came across them now. Only at night, or in the queer dusk hours, he caught glimpses of them moving hurriedly off from the hotel, and always desertwards. And their disregard, well calculated, enflamed his desire to the point when he almost decided to propose himself. Quite suddenly, then, the idea flashed through him--how do they come, these odd revelations, when the mind lies receptive like a plate sensitised by antic.i.p.ation?--that they were waiting for a certain date, and, with the notion, came Mansfield's remark about "the Night of Power," believed in by the old Egyptian Calendar as a time when the supersensuous world moves close against the minds of men with all its troop of possibilities. And the thought, once lodged in its corner of imagination, grew strong. He looked it up. Ten days from now, he found, Leyel-el-Sud would be upon him, with a moon, too, at the full. And this strange hint of guidance he accepted. In his present mood, as he admitted, smiling to himself, he could accept anything. It was part of it, it belonged to the adventure. But, even while he persuaded himself that it was play, the solemn reality, of what lay ahead increased amazingly, sketched darkly in his very soul.

These intervening days he spent as best he could--impatiently, a prey to quite opposite emotions. In the blazing sunshine he thought of it and laughed; but at night he lay often sleepless, calculating chances of escape. He never did escape, however. The Desert that watched little Helouan with great, unwinking eyes watched also every turn and twist he made. Like this oasis, he basked in the sun of older time, and dreamed beneath forgotten moons. The sand at last had crept into his inmost heart. It sifted over him.

Seeking a reaction from normal, everyday things, he made tourist trips; yet, while recognising the comedy in his att.i.tude, he never could lose sight of the grandeur that banked it up so hauntingly. These two contrary emotions grafted themselves on all he did and saw. He crossed the Nile at Bedrashein, and went again to the Tomb-World of Sakkara; but through all the chatter of veiled and helmeted tourists, the _bandar-log_ of our modern Jungle, ran this dark under-stream of awe their monkey methods could not turn aside. One world lay upon another, but this modern layer was a shallow crust that, like the phenomenon of the "desert-film," a mere angle of falling light could instantly obliterate. Beneath the sand, deep down, he pa.s.sed along the Street of Tombs, as he had often pa.s.sed before, moved then merely by historical curiosity and admiration, but now by emotions for which he found no name. He saw the enormous sarcophagi of granite in their gloomy chambers where the sacred bulls once lay, swathed and embalmed like human beings, and, in the flickering candle light, the mood of ancient rites surged round him, menacing his doubts and laughter. The least human whisper in these subterraneans, dug out first four thousand years ago, revived ominous Powers that stalked beside him, forbidding and premonitive. He gazed at the spots where Mariette, unearthing them forty years ago, found fresh as of yesterday the marks of fingers and naked feet--of those who set the sixty-five ton slabs in position. And when he came up again into the sunshine he met the eternal questions of the pyramids, overtopping all his mental horizons. Sand blocked all the avenues of younger emotion, leaving the channels of something in him incalculably older, open and clean swept.

He slipped homewards, uncomfortable and followed, glad to be with a crowd--because he was otherwise alone with more than he could dare to think about. Keeping just ahead of his companions, he crossed the desert edge where the ghost of Memphis walks under rustling palm trees that screen no stone left upon another of all its mile-long populous splendours. For here was a vista his imagination could realise; here he could know the comfort of solid ground his feet could touch. Gigantic Ramases, lying on his back beneath their shade and staring at the sky, similarly helped to steady his swaying thoughts. Imagination could deal with these.

And daily thus he watched the busy world go to and fro to its scale of tips and bargaining, and gladly mingled with it, trying to laugh and study guidebooks, and listen to half-fledged explanations, but always seeing the comedy of his poor attempts. Not all those little donkeys, bells tinkling, beads shining, trotting beneath their comical burdens to the tune of shouting and belabouring, could stem this tide of deeper things the woman had let loose in the subconscious part of him.

Everywhere he saw the mysterious camels go slouching through the sand, gurgling the water in their skinny, extended throats. Centuries pa.s.sed between the enormous knee-stroke of their stride. And, every night, the sunsets restored the forbidding, graver mood, with their crimson, golden splendour, their strange green shafts of light, then--sudden twilight that brought the Past upon him with an awful leap. Upon the stage then stepped the figures of this pair of human beings, chanting their ancient plainsong of incantation in the moonlit desert, and working their rites of unholy evocation as the priests had worked them centuries before in the sands that now buried Sakkara fathoms deep.

Then one morning he woke with a question in his mind, as though it had been asked of him in sleep and he had waked just before the answer came.

"Why do I spend my time sight-seeing, instead of going alone into the Desert as before? What has made me change?"

This latest mood now asked for explanation. And the answer, coming up automatically, startled him. It was so clear and sure--had been lying in the background all along. One word contained it:

Vance.

The sinister intentions of this man, forgotten in the rush of other emotions, a.s.serted themselves again convincingly. The human horror, so easily comprehensible, had been smothered for the time by the hint of unearthly revelations. But it had operated all the time. Now it took the lead. He dreaded to be alone in the Desert with this dark picture in his mind of what Vance meant to bring there to completion. This abomination of a selfish human will returned to fix its terror in him.

To be alone in the Desert meant to be alone with the imaginative picture of what Vance--he knew it with such strange certainty--hoped to bring about there.

There was absolutely no evidence to justify the grim suspicion. It seemed indeed far-fetched enough, this connection between the sand and the purpose of an evil-minded, violent man. But Henriot saw it true. He could argue it away in a few minutes--easily. Yet the instant thought ceased, it returned, led up by intuition. It possessed him, filled his mind with horrible possibilities. He feared the Desert as he might have feared the scene of some atrocious crime. And, for the time, this dread of a merely human thing corrected the big seduction of the other--the suggested "super-natural."

Side by side with it, his desire to join himself to the purposes of the woman increased steadily. They kept out of his way apparently; the offer seemed withdrawn; he grew restless, unable to settle to anything for long, and once he asked the porter casually if they were leaving the hotel. Lady Statham had been invisible for days, and Vance was somehow never within speaking distance. He heard with relief that they had not gone--but with dread as well. Keen excitement worked in him underground.

He slept badly. Like a schoolboy, he waited for the summons to an important examination that involved portentous issues, and contradictory emotions disturbed his peace of mind abominably.

VIII

But it was not until the end of the week, when Vance approached him with purpose in his eyes and manner, that Henriot knew his fears unfounded, and caught himself trembling with sudden antic.i.p.ation--because the invitation, so desired yet so dreaded, was actually at hand. Firmly determined to keep caution uppermost, yet he went unresistingly to a secluded corner by the palms where they could talk in privacy. For prudence is of the mind, but desire is of the soul, and while his brain of to-day whispered wariness, voices in his heart of long ago shouted commands that he knew he must obey with joy.

It was evening and the stars were out. Helouan, with her fairy twinkling lights, lay silent against the Desert edge. The sand was at the flood. The period of the Encroaching of the Desert was at hand, and the deeps were all astir with movement. But in the windless air was a great peace. A calm of infinite stillness breathed everywhere. The flow of Time, before it rushed away backwards, stopped somewhere between the dust of stars and Desert. The mystery of sand touched every street with its unutterable softness.

And Vance began without the smallest circ.u.mlocution. His voice was low, in keeping with the scene, but the words dropped with a sharp distinctness into the other's heart like grains of sand that p.r.i.c.ked the skin before they smothered him. Caution they smothered instantly; resistance too.

"I have a message for you from my aunt," he said, as though he brought an invitation to a picnic. Henriot sat in shadow, but his companion's face was in a patch of light that followed them from the windows of the central hall. There was a shining in the light blue eyes that betrayed the excitement his quiet manner concealed. "We are going--the day after to-morrow--to spend the night in the Desert; she wondered if, perhaps, you would care to join us?"

"For your experiment?" asked Henriot bluntly.

Vance smiled with his lips, holding his eyes steady, though unable to suppress the gleam that flashed in them and was gone so swiftly. There was a hint of shrugging his shoulders.

"It is the Night of Power--in the old Egyptian Calendar, you know," he answered with a.s.sumed lightness almost, "the final moment of Leyel-el-Sud, the period of Black Nights when the Desert was held to encroach with--with various possibilities of a supernatural order. She wishes to revive a certain practice of the old Egyptians. There _may_ be curious results. At any rate, the occasion is a picturesque one--better than this cheap imitation of London life." And he indicated the lights, the signs of people in the hall dressed for gaieties and dances, the hotel orchestra that played after dinner.

Henriot at the moment answered nothing, so great was the rush of conflicting emotions that came he knew not whence. Vance went calmly on.

He spoke with a simple frankness that was meant to be disarming. Henriot never took his eyes off him. The two men stared steadily at one another.

"She wants to know if you will come and help too--in a certain way only: not in the experiment itself precisely, but by watching merely and--" He hesitated an instant, half lowering his eyes.

"Drawing the picture," Henriot helped him deliberately.

"Drawing what you see, yes," Vance replied, the voice turned graver in spite of himself. "She wants--she hopes to catch the outlines of anything that happens--"

"Comes."

"Exactly. Determine the shape of anything that comes. You may remember your conversation of the other night with her. She is very certain of success."

This was direct enough at any rate. It was as formal as an invitation to a dinner, and as guileless. The thing he thought he wanted lay within his reach. He had merely to say yes. He did say yes; but first he looked about him instinctively, as for guidance. He looked at the stars twinkling high above the distant Libyan Plateau; at the long arms of the Desert, gleaming weirdly white in the moonlight, and reaching towards him down every opening between the houses; at the heavy ma.s.s of the Mokattam Hills, guarding the Arabian Wilderness with strange, peaked barriers, their sand-carved ridges dark and still above the Wadi Hof.

These questionings attracted no response. The Desert watched him, but it did not answer. There was only the shrill whistling cry of the lizards, and the sing-song of a white-robed Arab gliding down the sandy street.

And through these sounds he heard his own voice answer: "I will come--yes. But how can I help? Tell me what you propose--your plan?"

And the face of Vance, seen plainly in the electric glare, betrayed his satisfaction. The opposing things in the fellow's mind of darkness fought visibly in his eyes and skin. The sordid motive, planning a dreadful act, leaped to his face, and with it a flash of this other yearning that sought unearthly knowledge, perhaps believed it too. No wonder there was conflict written on his features.

Then all expression vanished again; he leaned forward, lowering his voice.

"You remember our conversation about there being types of life too vast to manifest in a single body, and my aunt's belief that these were known to certain of the older religious systems of the world?"

"Perfectly."

"Her experiment, then, is to bring one of these great Powers back--we possess the sympathetic ritual that can rouse some among them to activity--and win it down into the sphere of our minds, our minds heightened, you see, by ceremonial to that stage of clairvoyant vision which can perceive them."

"And then?" They might have been discussing the building of a house, so naturally followed answer upon question. But the whole body of meaning in the old Egyptian symbolism rushed over him with a force that shook his heart. Memory came so marvellously with it.

"If the Power floods down into our minds with sufficient strength for actual form, to note the outline of such form, and from your drawing model it later in permanent substance. Then we should have means of evoking it at will, for we should have its natural Body--the form it built itself, its signature, image, pattern. A starting-point, you see, for more--leading, she hopes, to a complete reconstruction."

"It might take actual shape--a.s.sume a bodily form visible to the eye?"

repeated Henriot, amazed as before that doubt and laughter did not break through his mind.

"We are on the earth," was the reply, spoken unnecessarily low since no living thing was within earshot, "we are in physical conditions, are we not? Even a human soul we do not recognise unless we see it in a body--parents provide the outline, the signature, the sigil of the returning soul. This," and he tapped himself upon the breast, "is the physical signature of that type of life we call a soul. Unless there is life of a certain strength behind it, no body forms. And, without a body, we are helpless to control or manage it--deal with it in any way.

We could not know it, though being possibly _aware_ of it."

"To be aware, you mean, is not sufficient?" For he noticed the italics Vance made use of.

"Too vague, of no value for future use," was the reply. "But once obtain the form, and we have the natural symbol of that particular Power. And a symbol is more than image, it is a direct and concentrated expression of the life it typifies--possibly terrific."

"It may be a body, then, this symbol you speak of."

"Accurate vehicle of manifestation; but 'body' seems the simplest word."

Vance answered very slowly and deliberately, as though weighing how much he would tell. His language was admirably evasive. Few perhaps would have detected the profound significance the curious words he next used unquestionably concealed. Henriot's mind rejected them, but his heart accepted. For the ancient soul in him was listening and aware.

"Life, using matter to express itself in bodily shape, first traces a geometrical pattern. From the lowest form in crystals, upwards to more complicated patterns in the higher organisations--there is always first this geometrical pattern as skeleton. For geometry lies at the root of all possible phenomena; and is the mind's interpretation of a living movement towards shape that shall express it." He brought his eyes closer to the other, lowering his voice again. "Hence," he said softly, "the signs in all the old magical systems--skeleton forms into which the Powers evoked descended; outlines those Powers automatically built up when using matter to express themselves. Such signs are material symbols of their bodiless existence. They attract the life they represent and interpret. Obtain the correct, true symbol, and the Power corresponding to it can approach--once roused and made aware. It has, you see, a ready-made mould into which it can come down."

"Once roused and made aware?" repeated Henriot questioningly, while this man went stammering the letters of a language that he himself had used too long ago to recapture fully.

"Because they have left the world. They sleep, unmanifested. Their forms are no longer known to men. No forms exist on earth to-day that could contain them. But they may be awakened," he added darkly. "They are bound to answer to the summons, if such summons be accurately made."
