In a dark wainscoted room overlooking that branch of the Seine which divides the northern part of Paris from the Isle of the City, Gilles de Retz, lately Chamberlain of the King of France, sat writing. The hotel had recently been redecorated after the sojourn of the English. Wooden pavements had again been placed in the rooms where the barbarians had strewed their rushes and trampled upon their rotting fishbones. Noble furniture from the lathes of Poitiers, decorated with the royal ermines of Brittany, stood about the many alcoves. The table itself whereon the famous soldier wrote was closed in with drawers and shelves which descended to the floor and seemed to surround the occupant like a cell.

Before de Retz stood a curious inkstand, made by some cunning jeweller out of the upper half of a human skull of small size, cut across at the eye-holes, inverted, and set in silver with a rim of large rubies. This was filled with ink of a startling vermilion colour.

The document which Gilles de Retz was busy transcribing upon sheets of noble vellum in this strange ink was of an equally mysterious character. The upper part had the appearance of a charter engrossed by the hand of some deft legal scribe, but the words which followed were as startling as the vehicle by means of which they were made to stand out from the vellum.

"Unto Barran-Sathanas; Lord most glorious and puissant in hell beneath and in the earth above, I, his unworthy servitor Gilles de Retz, make my vows, hereby forever renouncing God, Christ, and the Blessed Saints."

To this appalling introduction succeeded many lines of close and delicate script, interspersed with curious cabalistic signs, in which that of the cross reversed could frequently be detected. Gilles de Retz wrote rapidly, rising only at intervals to throw a fresh log of wood across the vast iron dogs on either side of the wide fireplace, as the rain from the northwest beat more and more fiercely upon the small glazed panes of the window and howled among the innumerable gargoyles and twisted roof-stacks of the Hotel de Pornic.

Within the chamber itself, in the intervals of the storm, a low continuous growling made itself evident. At first it was disregarded by the writer, but presently, by its sheer pertinacity, the sound so irritated him that he rose from his seat, and, striding to a narrow door covered with a heavy curtain, he threw it wide open to the wall. Then through the black oblong so made, a huge and shaggy she-wolf slouched slowly into the room.

The marshal kicked the brute impatiently with his slippered foot as she entered, and, strange to relate, the wolf slunk past him with the cowed air of a dog conscious of having deserved punishment.

"Astarte, vilest beast," he cried, "have I not a thousand times warned you to be silent and wait outside when I am at work within my chamber?"

The she-wolf eyed her master as he went back towards his table. Then, seeing him lift his pen, with a sigh of content she dropped down upon the warm hearthstone, lying with her haunches towards the blazing logs and her bristling head couched upon her paws. Her yellow shining eyes blinked sleepily and approvingly at him, while with her tongue she rasped the soft pads of her feet one by one, biting away the fur from between the toes with her long and gleaming teeth. Presently Astarte appeared to doze off. Her eyes were shut, her attitude relaxed. But so soon as ever her master moved even an inch to consult a marked list of dates which hung on a hook beside him, or leaned over to dip a quill in his scarlet ink, the flashing yellow eye and the gleam of white teeth underneath told that Astarte was awake and intently watching every movement of the worker.

Through the heavy boom of the storm without, the thresh of the rain upon the lattice casement, and the irregular whipping gusts which shook the house, the soft wheeze of the engrossing quill could be heard, the crackle of the burning logs and the heavy regular breathing of the couchant she-wolf being the only other sounds audible within the apartment.

Gilles de Retz wrote on, smiling to himself as he added line after line to his manuscript. His beard shone with a truculent blue-black lustre. For the moment the aged look had quite gone out of his face. His cheek appeared flushed with the hues of youth and reinvigorated hope, yet withal of a youth without innocence or charm. Rather it seemed as if fresh blood had been injected into the veins of some aged demon, moribund and cruel, giving, instead of health or grace, only a new lease of cruelty and lust.

Presently another door opened, the main entrance of the apartment this time, not the small private portal through which Astarte the wolf had been admitted. A girl came in, thrusting aside the curtain, and, for the space of a moment, holding it outstretched with an arm gowned in pure white before dropping it with a rustle of heavy silken fabric upon the ground.

The Marshal de Retz wrote on without appearing to be conscious of any new presence in his private chamber. The girl stood regarding him, with eyes that blazed with an intent so deadly and a hate so all-possessing that the yellow treachery in those of Astarte the she-wolf appeared kind and affectionate by contrast.

At the girl's entrance that shaggy beast had raised herself upon her fore paws, and presently she gave vent to a low growl, half of distrust and half of warning, which at once reached the ears of the busy worker.

Gilles de Retz looked up quickly, and, catching sight of the Lady Sybilla, with a sweep of his hand he thrust his manuscript into an open drawer of the escritoire.

"Ah, Sybilla," he said, leaning back in his chair with an air of easy familiarity, "you are more sparing of your visits to me than of yore. To what do I owe the pleasure and honour of this one?"

The girl eyed him long before answering. She stood statue-still by the curtain at the entrance of the apartment, ignoring the chair which the marshal had offered her with a bow and a courteous wave of his hand.

"I have come," she made answer at last, in the deep even tones which she had used before the council of the traitors at Stirling, "to demand from you, Messire Gilles de Retz, what you mean to do with the little Margaret Douglas and her companion, whom you wickedly kidnapped from their own country and have brought with you in your train to France?"

"I have satisfaction in informing you," replied the marshal, suavely, "that it is my purpose to dispose of both these agreeable young ladies entirely according to my own pleasure."

The girl caught at her breast with her hand, as if to stay a sudden spasm of pain.

"Not at Tiffauges—" she gasped, "not at ChamptocÉ?"

The marshal leaned back, enjoying her terror, as one tastes in slow sips a rare brand of wine. He found the flavour of her fears delicious.

"No, Sybilla," he replied at last, "neither at ChamptocÉ nor yet at Tiffauges—for the present, that is, unless some of your Scottish friends come over to rescue them out of my hands."

"How, then, do you intend to dispose of them?" she urged.

"I shall send them to your puking sister and her child, hiding their heads and sewing their samplers at Machecoul. What more can you ask? Surely the young and fair are safe in such worthy society, even if they may chance to find it a little dull."

"How can I believe him, or know that for once he will forego his purposes of hell?" Sybilla murmured, half to herself.

The Marshal de Retz smiled, if indeed the contraction of muscles which revealed a line of white teeth can be called by that name. In the sense in which Astarte would have smiled upon a defenceless sheepfold, so Gilles de Retz might have been said to smile at his visitor.

"You may believe me, sweet Lady Sybilla," said the marshal, "because there is one vice which it is needless for me to practise in your presence, that of uncandour. I give you my word that unless your friends come worrying me from the land of Scots, the maids shall not die. Perhaps it were better to warn any visitors that even at Machecoul we are accustomed to deal with such cases. Is it not so, Astarte?"

At the sound of her name the huge wolf rose slowly, and, walking to her master's knee, she nosed upon him like a favourite hound.

"And if your intent be not that which causes fear to haunt the precincts of your palaces like a night-devouring beast, and makes your name an execration throughout Brittany and the VendÉe, why have you carried the little child and the other pretty fool forth from their country? Was it not enough that you should slay the brothers? Wherefore was it necessary utterly to cut off the race of the Douglases?"

"Sybilla, dear sister of my sainted Catherine," purred the marshal, "it is your privilege that you should speak freely. When it is pleasing to me I may even answer you. It pleases me now, listen—you know of my devotion to science. You are not ignorant at what cost, at what vast sacrifices, I have in secret pushed my researches beyond the very confines of knowledge. The powers of the underworlds are revealing themselves to me, and to me alone. Evil and good alike shall be mine. I alone will pluck the blossom of fire, and tear from hell and hell's master their cherished mystery."

He paused as if mentally to recount his triumphs, and then continued.

"But at the moment of success I am crossed by a prejudice. The ignorant people clamour against my life—canaille! I regard them not. But nevertheless their foolish prejudices reach other ears. Hearken!"

And like a showman he beckoned Sybilla to the window. A low roar of human voices, fitful yet sustained, made itself distinctly audible above the shriller hooting of the tempest.

"Open the window!" he commanded, standing behind the curtain.

The girl unhasped the brazen hook and looked out. Beneath her a little crowd of poor people had collected about a woman who was beating with bleeding hands upon the shut door of the Hotel de Pornic.

"Justice! justice!" cried the woman, her hands clasped and her long black hair streaming down her shoulders, "give me my child, my little Pierre. Yester-eve he was enticed into the monster's den by his servant Poitou, and I shall never see him more! Give me my boy, murderer! Restore me my son!"

And the answering roar of the people's voices rose through the open window to the ears of the marshal. "Give the woman her son, Gilles de Retz!"

At that moment the woman caught sight of Sybilla. Instantly she changed her tone from entreaty to fierce denunciation.

"Behold the witch, friends, let us tear her to pieces. She is kept young and beautiful by drinking the blood of children. Throw thyself down, Jezebel, that the dogs may eat thee in the streets."

And a shout went up from the populace as Sybilla shut to the window, shuddering at the horrors which surrounded her.

The Marshal de Retz had not moved, watching her face without regarding the noise outside. Now he went back to his chair, and bending his slender white fingers together, he looked up at her.

Presently he struck a silver bell by his side three times, and the mellow sound pervaded the house.

Poitou appeared instantly at the inner door through which the she-wolf had entered.

"How does it go?" asked the marshal, with his usual careless easy grace.

"Not well," said Poitou, shaking his head; "that is, rightly up to a point, and then—all wrong!"

For the first time the countenance of the marshal appeared troubled.

"And I was sure of success this time. We must try them younger. It is all so near, yet, strangely it escapes us. Well, Poitou, I shall come in a little when I have finished with this lady. Tell De SillÉ to expect me."

Poitou bowed respectfully and was withdrawing, too well trained to smile or even lift his eyes to where Sybilla stood by the window.

His master appeared to recollect himself.

"A moment, Poitou—there are some troublesome people of the city rabble at the door. Bid the guard turn out, and thrust them away. Tell them to strike not too gently with the flats of their swords and the butts of their spears."

Gilles de Retz listened for some time after the disappearance of his familiar. Presently the low droning note of popular execration changed into sharper exclamations of hatred, mingled with cries of pain.

Then the marshal smiled, and rubbed his hands lightly one over the other.

"That's my good lads," he said; "hear the rattle of the spear-hilts upon the paving-stones? They are bringing the butts into close acquaintance with certain very ill-shod feet. Ah, now they are gone!"

The marshal took a long breath and went on, half to himself and half to Sybilla.

"But I own it is all most inconvenient," he said, thoughtfully. "Here in Paris, in King Charles's country, it does not so greatly matter. For the affair in Scotland has set me right with the King and in especial with the Dauphin. By the death of the Douglases I have given back the duchy of Touraine to the kings of France after three generations. I have therefore well earned the right to be allowed to seek knowledge in mine own way."

"The service of the devil is a poor way to knowledge," said the girl.

"Ah, there it is," said the marshal, raising his hand with gentle deprecation, "even you, who are so highly privileged, are not wholly superior to vulgar prejudice. I keep a college of priests for the service of God and the Virgin. They have done me but little good. Surely therefore I may be allowed a little service of That Other, who has afforded me such exquisite pleasure and aided me so much. The Master of Evil knows all things, and he can help whom he will to the secrets of wealth, of power, and of eternal youth."

"Have you gained any of these by the aid of that Master whom you serve?" asked the Lady Sybilla, with great quiet in her voice.

"Nay, not yet," cried the marshal, moved for the first time, "not yet—perhaps because I have sought too eagerly and hotly. But I am now at least within sight of the wondrous goal. See," he added, with genuine excitement labouring in his voice, "see—I am still a young man, yet though I, Gilles de Retz, was born to the princeliest fortune in France, and by marriage added another, they have both been spent well nigh to the last stiver in learning the hidden secrets of the universe. I am still a young man, I say, but look at my whitening hair, count the deep wrinkles on my forehead, consider my withered cheek. Have I not tasted all agonies, renounced all delights, and cast aside all scruples that I might win back my youth, and with it the knowledge of good and evil?"

Sybilla went to the door and stood again by the curtain.

"Then you swear by your own God that you will let no evil befall the Scottish maids?" she said.

"I have told you already—let that suffice!" he replied with sudden coldness; "you know that, like the Master whom I serve, I can keep my word. I will not harm them, so long as their Scottish kinsfolk come not hither meddling with my purposes. I have enough of meddlers in France without adding outlanders thereto! I cannot keep a new and permanent danger at grass within my gates."

The Lady Sybilla passed through the portal by which she had entered, without adieu or leave-taking of any kind. Gilles de Retz rose as soon as the curtain had fallen, and shook himself with a yawn, like one who has got through a troublesome necessary duty. Then he walked to the window and looked out. The woman had come back and was kneeling before the Hotel de Pornic.

At sight of him she cried with sudden shrillness, "My lord, my great lord, give me back my child—my little Pierre. He is my heart's heart. My lord, he never did you any harm in all his innocent life!"

The Marshal de Retz shut the window with a shrug of protest against the vulgarity of prejudice. He did not notice four men in the garb of pilgrims who stood in the dark of a doorway opposite.

"This is both unnecessary and excessively discomposing," he muttered; "I fear Poitou has not been judicious enough in his selections."

He turned towards the private door, and as he did so Astarte the she-wolf rose and silently followed him with her head drooped forward. He went along a dark passage and pushed open a little iron door. A bright light as of a furnace burnt up before him, and the heat was overpowering as it rushed like a ruddy tide-race against his face.

"Well, Poitou, does it go better?" he said cheerfully, "or must we try them of the other sex and somewhat younger, as I at first proposed?"

He let the door slip back, and the action of a powerful spring shut out Astarte. Whereat she sat down on her haunches in the dark of the passage, and showed her gleaming teeth in a grin, as, with cocked ears, she listened to the sounds from within the secret laboratory of the Marshal de Retz.
