And he waved a hand towards the tall cloaked figure at his side.

La Voisin looked at the masked face.

"Velvet faces tell me little, Madame la Marquise," she said calmly.

"Nor, believe me, will the King look at a countenance that you conceal from me."

There was an exclamation of surprise and anger from Madame de Montespan.

She plucked off her mask.

"You knew me?"

"Can you wonder?" asked La Voisin, "since I have told you what you carry concealed in your heart?"

Madame de Montespan was as credulous as only the very devout can be.

"Since that is so, since you know already what I seek, tell me can you procure it me?" she asked in a fever of excitement. "I will pay well."

La Voisin smiled darkly.

"Obdurate, indeed, is the case that will not yield to such medicine as mine," she said. "Let me consider first what must be done. In a few days I shall bring you word. But have you courage for a great ordeal?"

"For any ordeal that will give me what I want."

"In a few days, then, you shall hear from me," said the witch, and so dismissed the great lady.

Leaving a heavy purse behind her, as Vanens had instructed her, the Marchioness departed with her escort. And there, with that initiation, as far as we can ascertain, ended Louis de Vanens's connection with the affair.

At Clagny Madame de Montespan waited for three days in a fever of impatience for the coming of the witch. But when at last La Voisin presented herself, the proposal that she had to make was one before which the Marchioness recoiled in horror and some indignation.

The magic that La Voisin suggested involved a coadjutor, the Abbe Guibourg, and the black mass to be celebrated by him. Madame de Montespan had heard something of these dread sacrificial rites to Satan; sufficient to fill her with loathing and disgust of the whitefaced, beady-eyed woman who dared to insult her by the proposal. She fumed and raged a while, and even went near to striking La Voisin, who looked on with inscrutable face and stony, almost contemptuous, indifference.

Before that impenetrable, almost uncanny, calm, Madame de Montespan's fury at last abated. Then the urgency of her need becoming paramount, she desired more clearly to be told what would be expected of her.

What the witch told her was more appalling than anything she could have imagined. But La Voisin argued:

"Can anything be accomplished without cost? Can anything be gained in this life without payment of some kind?"

"But the price of this is monstrous!" Madame de Montespan protested.

"Measure it by the worldly advantages to be gained. They are not small, madame. To enjoy boundless wealth, boundless power, and boundless honour, to be more than queen--is not all this worth some sacrifice?"

To Madame de Montespan it must have been worth any sacrifice in this world or the next, since in the end she conquered her disgust, and agreed to lend herself to this horror.

Three masses, she was told, would be necessary to ensure success, and it was determined that they should be celebrated in the chapel of the Chateau de Villebousin, where Guibourg had been almoner, to which he had access, and which was at the time untenanted.

The chateau was a gloomy mediaeval fortress, blackened by age, and standing, surrounded by a moat, in a lonely spot some two miles to the south of Paris. Thither on a dark, gusty night of March came Madame de Montespan, accompanied by her confidential waiting-woman, Mademoiselle Desceillets. They left the coach to await them on the Orleans road, and thence, escorted by a single male attendant, they made their way by a rutted, sodden path towards the grim castle looming faintly through the enveloping gloom.

The wind howled dismally about the crenellated turrets; and a row of poplars, standing like black, phantasmal guardians of the evil place, bent groaning before its fury. From the running waters of the moat, swollen by recent rains, came a gurgling sound that was indescribably wicked.

Desocillets was frightened by the dark, the desolate loneliness and eeriness of the place; but she dared utter no complaint as she stumbled forward over the uneven ground, through the gloom and the buffeting wind, compelled by the suasion of her mistress's imperious will. Thus, by a drawbridge spanning dark, oily waters, they came into a vast courtyard and an atmosphere as of mildew. A studded door stood ajar, and through the gap, from a guiding beacon of infamy, fell a rhomb of yellow light, suddenly obscured by a squat female figure when the steps of the Marchioness and her companions fell upon the stones of the yard.

It was La Voisin who stood on the threshold to receive her client. In the stone-flagged hall behind her the light of a lantern revealed her daughter, Marguerite Monvoisin, and a short, crafty-faced, misshapen fellow in black homespun and a red wig--a magician named Lesage, one of La Voisin's coadjutors, a rogue of some talent who exploited the witches of Paris to his own profit.

Leaving Leroy--the Marchioness's male attendant below in this fellow's company, La Voisin took up a candle and lighted Madame de Montespan up the broad stone staircase, draughty and cold, to the ante-room of the chapel on the floor above. Mademoiselle Desceillets followed closely and fearfully, and Marguerite Monvoisin came last.

They entered the ante-room, a spacious chamber, bare of furniture save for an oaken table in the middle, some faded and mildewed tapestries, and a cane-backed settle of twisted walnut over against the wall. An alabaster lamp on the table made an island of light in that place of gloom, and within the circle of its feeble rays stood a gross old man of some seventy years of age in sacerdotal garments of unusual design: the white alb worn over a greasy cassock was studded with black fir-cones; the stole and maniple were of black satin, with fir-cones wrought in yellow thread.

His inflamed countenance was of a revolting hideousness: his cheeks were covered by a network of blue veins, his eyes squinted horribly, his lips vanished inwards over toothless gums, and a fringe of white hair hung in matted wisps from his high, bald crown. This was the infamous Abbe Guibourg, sacristan of Saint Denis, an ordained priest who had consecrated himself to the service of the Devil.

He received the great lady with a low bow which, despite herself, she acknowledged by a shudder. She was very pale, and her eyes were dilating and preternaturally bright. Fear began to possess her, yet she suffered herself to be ushered into the chapel, which was dimly illumined by a couple of candles standing beside a basin on a table. The altar light had been extinguished. Her maid would have hung back, but that she feared to be parted from her mistress. She passed in with her in the wake of Guibourg, and followed by La Voisin, who closed the door, leaving her daughter in the ante-room.

Although she had never been a participant in any of the sorceries practised by her mother, yet Marguerite was fully aware of their extent, and more than guessed what horrors were taking place beyond the closed doors of the chapel. The very thought of them filled her with loathing and disgust as she sat waiting, huddled in a corner of the settle. And yet when presently through the closed doors came the drone of the voice of that unclean celebrant, to blend with the whine of the wind in the chimney, Marguerite, urged by a morbid curiosity she could not conquer, crept shuddering to the door, which directly faced the altar, and going down on her knees applied her eye to the keyhole.

What she saw may very well have appalled her considering the exalted station of Madame de Montespan. She beheld the white, sculptural form of the royal favourite lying at full length supine upon the altar, her arms outstretched, holding a lighted candle in each hand. Immediately before her stood the Abbe Guibourg, his body screening the chalice and its position from the eye of the watching girl.

She heard the whine of his voice pattering the Latin of the mass, which he was reciting backwards from the last gospel; and occasionally she heard responses muttered by her mother, who with Mademoiselle Desceillets was beyond Marguerite's narrow range of vision.

Apart from the interest lent to the proceedings by the presence of the royal favourite the affair must have seemed now very stupid and pointless to Marguerite, although she would certainly not have found it so had she known enough Latin to understand the horrible perversion of the Credo. But when the Offertory was reached, matters suddenly quickened. In stealing away from the door, she was no more than in time to avoid being caught spying by her mother, who now issued from the chapel.

La Voisin crossed the ante-room briskly and went out.

Within a very few minutes she was back again, her approach now heralded by the feeble, quavering squeals of a very young child.

Marguerite Monvoisin was sufficiently acquainted with the ghastly rites to guess what was impending. She was young, and herself a mother.

She had her share of the maternal instinct alive in every female animal--with the occasional exception of the human pervert--and the hoarse, plaintive cries of that young child chilled her to the soul with horror. She felt the skin roughening and tightening upon her body, and a sense of physical sickness overcame her. That and the fear of her mother kept her stiff and frozen in an angle of the settle until La Voisin had passed through and reentered the chapel bearing that piteous bundle in her arms.

Then, when the door had closed again, the girl, horrified and fascinated, sped back to watch. She saw that unclean priest turn and receive the child from La Voisin. As it changed hands its cries were stilled.

Guibourg faced the altar once more, that little wisp of humanity that was but a few days old held now aloft, naked, in his criminal hands.

His muttering, slobbering voice pronouncing the words of that demoniac consecration reached the ears of the petrified girl at the keyhole.

"Ashtaroth, Asmodeus, Princes of Affection, I conjure you to acknowledge the sacrifice I offer to you of this child for the things I ask of you, which are that the King's love for me shall be continued, and that honoured by princes and princesses nothing shall be denied me of all that I may ask."

A sudden gust of wind smote and rattled the windows of the chapel and the ante-room, as if the legions of hell had flung themselves against the walls of the chateau. There was a rush and clatter in the chimney of the ante-room's vast, empty fireplace, and through the din Marguerite, as her failing limbs sank under her and she slithered down in a heap against the chapel door, seemed to hear a burst of exultantly cruel satanic laughter. With chattering teeth and burning eyes she sat huddled, listening in terror. The child began to cry again, more violently, more piteously; then, quite suddenly, there was a little choking cough, a gurgle, the chink of metal against earthenware, and silence.

When some moments later the squat figure of La Voisin emerged from the chapel, Marguerite was back in the shadows, hunched on the settle to which she had crawled. She saw that her mother now carried a basin under her arm, and she did not need the evidence of her eyes to inform her of the dreadful contents that the witch was bearing away in it.

Meanwhile in the chapel the ineffably blasphemous rites proceeded. To the warm human blood which had been caught in the consecrated chalice, Guibourg had added, among other foulnesses, powdered cantharides, the dust of desiccated moles, and the blood of bats. By the addition of flour he had wrought the ingredients into an ineffable paste, and over this, through the door, which La Voisin had left ajar, Marguerite heard his voice pronouncing the dread words of Transubstantiation.

Marguerite's horror mounted until it threatened to suffocate her. It was as if some hellish miasma, released by Guibourg's monstrous incantations, crept through to permeate and poison the air she breathed.

It would be a half-hour later when Madame de Montespan at last came out.

She was of a ghastly pallor, her limbs shook and trembled under her as she stepped forth, and there was a wild horror in her staring eyes. Yet she contrived to carry herself almost defiantly erect, and she spoke sharply to the half-swooning Desceillets, who staggered after her.

She took her departure from that unholy place bearing with her the host compounded of devilish ingredients which when dried and reduced to powder was to be administered to the King to ensure the renewal of his failing affection for her.

The Marchioness contrived that a creature of her own, an officer of the buttery in her pay, should introduce it into the royal soup. The immediate and not unnatural result was that the King was taken violently ill, and Madame de Montespan's anxiety and suspense were increased thereby. On his recovery, however, it would seem that the demoniac sacrament--thrice repeated by then--had not been in vain.

The sequel, indeed, appeared to justify Madame de Montespan's faith in sorcery, and to compensate her for all the horror to which in her despair she had submitted. Madame de Ludres found herself coldly regarded by the convalescent King. Very soon she was discarded, the Widow Scarron neglected, and the fickle monarch was once more at the feet of the lovely marchioness, her utter and devoted slave.

Thus was Madame de Montespan "thunderously triumphant" once more, and established as firmly as 'ever in the Sun-King's favour. Madame de Sevigne, in speaking of this phase of their relations, dilates upon the completeness of the reconciliation, and tells us that the ardour of the first years seemed now to have returned. And for two whole years it continued thus. Never before had Madame de Montespan's sway been more absolute, no shadow came to trouble, the serenity of her rule.
