For one moment there was dead silence in the little boudoir. Beyond, from the brilliant ball-room, the sweet notes of the gavotte, the frou-frou of rich dresses, the talk and laughter of a large and merry crowd, came as a strange, weird accompaniment to the drama which was being enacted here.
Sir Andrew had not uttered another word. Then it was that that extra sense became potent in Marguerite Blakeney. She could not see, for her two eyes were closed, she could not hear, for the noise from the ball-room drowned the soft rustle of that momentous scrap of paper; nevertheless she knew-as if she had both seen and heard--that Sir Andrew was even now holding the paper to the flame of one of the candles.

At the exact moment that it began to catch fire, she opened her eyes, raised her hand and, with two dainty fingers, had taken the burning scrap of paper from the young man's hand. Then she blew out the flame, and held the paper to her nostril with perfect unconcern.

"How thoughtful of you, Sir Andrew," she said gaily, "surely 'twas your grandmother who taught you that the smell of burnt paper was a sovereign remedy against giddiness."

She sighed with satisfaction, holding the paper tightly between her jewelled fingers; that talisman which perhaps would save her brother Armand's life. Sir Andrew was staring at her, too dazed for the moment to realize what had actually happened; he had been taken so completely by surprise, that he seemed quite unable to grasp the fact that the slip of paper, which she held in her dainty hand, was one perhaps on which the life of his comrade might depend.

Marguerite burst into a long, merry peal of laughter.

"Why do you stare at me like that?" she said playfully. "I assure you I feel much better; your remedy has proved most effectual. This room is most delightedly cool," she added, with the same perfect composure, "and the sound of the gavotte from the ball-room is fascinating and soothing."

She was prattling on in the most unconcerned and pleasant way, whilst Sir Andrew, in an agony of mind, was racking his brains as to the quickest method he could employ to get that bit of paper out of that beautiful woman's hand. Instinctively, vague and tumultuous thoughts rushed through his mind: he suddenly remembered her nationality, and worst of all, recollected that horrible take anent the Marquis de St. Cyr, which in England no one had credited, for the sake of Sir Percy, as well as for her own.

"What? Still dreaming and staring?" she said, with a merry laugh, "you are most ungallant, Sir Andrew; and now I come to think of it, you seemed more startled than pleased when you saw me just now. I do believe, after all, that it was not concern for my health, nor yet a remedy taught you by your grandmother that caused you to burn this tiny scrap of paper. . . . I vow it must have been your lady love's last cruel epistle you were trying to destroy. Now confess!" she added, playfully holding up the scrap of paper, "does this contain her final CONGE, or a last appeal to kiss and make friends?"

"Whichever it is, Lady Blakeney," said Sir Andrew, who was gradually recovering his self-possession, "this little note is undoubtedly mine, and. . ."
Not caring whether his action was one that would be styled ill-bred towards a lady, the young man had made a bold dash for the note; but Marguerite's thoughts flew quicker than his own; her actions under pressure of this intense excitement, were swifter and more sure. She was tall and strong; she took a quick step backwards and knocked over the small Sheraton table which was already top-heavy, and which fell down with a crash, together with the massive candelabra upon it.

She gave a quick cry of alarm:

"The candles, Sir Andrew--quick!"

There was not much damage done; one or two of the candles had blown out as the candelabra fell; others had merely sent some grease upon the valuable carpet; one had ignited the paper shade aver it. Sir Andrew quickly and dexterously put out the flames and replaced the candelabra upon the table; but this had taken him a few seconds to do, and those seconds had been all that Marguerite needed to cast a quick glance at the paper, and to note its contents--a dozen words in the same distorted handwriting she had seen before, and bearing the same device--a star-shaped flower drawn in red ink.

When Sir Andrew once more looked at her, he only saw upon her face alarm at the untoward accident and relief at its happy issue; whilst the tiny and momentous note had apparently fluttered to the ground. Eagerly the young man picked it up, and his face looked much relieved, as his fingers closed tightly over it.

"For shame, Sir Andrew," she said, shaking her head with a playful sigh, "making havoc in the heart of some impressionable duchess, whilst conquering the affections of my sweet little Suzanne. Well, well! I do believe it was Cupid himself who stood by you, and threatened the entire Foreign Office with destruction by fire, just on purpose to make me drop love's message, before it had been polluted by my indiscreet eyes. To think that, a moment longer, and I might have known the secrets of an erring duchess."

"You will forgive me, Lady Blakeney," said Sir Andrew, now as calm as she was herself, "if I resume the interesting occupation which you have interrupted?"

"By all means, Sir Andrew! How should I venture to thwart the love-god again? Perhaps he would mete out some terrible chastisement against my presumption. Burn your love-token, by all means!"

Sir Andrew had already twisted the paper into a long spill, and was once again holding it to the flame of the candle, which had remained alight. He did not notice the strange smile on the face of his fair VIS-A-VIS, so intent was he on the work of destruction; perhaps, had he done so, the look of relief would have faded from his face. He watched the fateful note, as it curled under the flame. Soon the last fragment fell on the floor, and he placed his heel upon the ashes.

"And now, Sir Andrew," said Marguerite Blakeney, with the pretty nonchalance peculiar to herself, and with the most winning of smiles, "will you venture to excite the jealousy of your fair lady by asking me to dance the minuet?"

CHAPTER XIII EITHER--OR?

The few words which Marguerite Blakeney had managed to read on the half-scorched piece of paper, seemed literally to be the words of Fate. "Start myself tomorrow. . . ." This she had read quite distinctly; then came a blur caused by the smoke of the candle, which obliterated the next few words; but, right at the bottom, there was another sentence, like letters of fire, before her mental vision, "If you wish to speak to me again I shall be in the supper-room at one o'clock precisely." The whole was signed with the hastily-scrawled little device--a tiny star-shaped flower, which had become so familiar to her.

One o'clock precisely! It was now close upon eleven, the last minuet was being danced, with Sir Andrew Ffoulkes and beautiful Lady Blakeney leading the couples, through its delicate and intricate figures.

Close upon eleven! the hands of the handsome Louis XV. clock upon its ormolu bracket seemed to move along with maddening rapidity. Two hours more, and her fate and that of Armand would be sealed. In two hours she must make up her mind whether she will keep the knowledge so cunningly gained to herself, and leave her brother to his fate, or whether she will wilfully betray a brave man, whose life was devoted to his fellow-men, who was noble, generous, and above all, unsuspecting. It seemed a horrible thing to do. But then, there was Armand! Armand, too, was noble and brave, Armand, too, was unsuspecting. And Armand loved her, would have willingly trusted his life in her hands, and now, when she could save him from death, she hesitated. Oh! it was monstrous; her brother's kind, gentle face, so full of love for her, seemed to be looking reproachfully at her. "You might have saved me, Margot!" he seemed to say to her, "and you chose the life of a stranger, a man you do not know, whom you have never seen, and preferred that he should be safe, whilst you sent me to the guillotine!"

All these conflicting thoughts raged through Marguerite's brain, while, with a smile upon her lips, she glided through the graceful mazes of the minuet. She noted--with that acute sense of hers--that she had succeeded in completely allaying Sir Andrew's fears. Her self-control had been absolutely perfect--she was a finer actress at this moment, and throughout the whole of this minuet, than she had ever been upon the boards of the Comedie Francaise; but then, a beloved brother's life had not depended upon her histrionic powers.

She was too clever to overdo her part, and made no further allusions to the supposed BILLET DOUX, which had caused Sir Andrew Ffoulkes such an agonising five minutes. She watched his anxiety melting away under her sunny smile, and soon perceived that, whatever doubt may have crossed his mind at the moment, she had, by the time the last bars of the minuet had been played, succeeded in completely dispelling it; he never realised in what a fever of excitement she was, what effort it cost her to keep up a constant ripple of BANAL conversation.

When the minuet was over, she asked Sir Andrew to take her into the next room.

"I have promised to go down to supper with His Royal Highness," she said, "but before we part, tell me. . .am I forgiven?"

"Forgiven?"

"Yes! Confess, I gave you a fright just now. . . . But remember, I am not an English woman, and I do not look upon the exchanging of BILLET DOUX as a crime, and I vow I'll not tell my little Suzanne. But now, tell me, shall I welcome you at my water-party on Wednesday?"

"I am not sure, Lady Blakeney," he replied evasively. "I may have to leave London to-morrow."

"I would not do that, if I were you," she said earnestly; then seeing the anxious look reappearing in his eyes, she added gaily; "No one can throw a ball better than you can, Sir Andrew, we should so miss you on the bowling-green."

He had led her across the room, to one beyond, where already His Royal Highness was waiting for the beautiful Lady Blakeney.

"Madame, supper awaits us," said the Prince, offering his arm to Marguerite, "and I am full of hope. The goddess Fortune has frowned so persistently on me at hazard, that I look with confidence for the smiles of the goddess of Beauty."

"Your Highness has been unfortunate at the card tables?" asked Marguerite, as she took the Prince's arm.

"Aye! most unfortunate. Blakeney, not content with being the richest among my father's subjects, has also the most outrageous luck. By the way, where is that inimitable wit? I vow, Madam, that this life would be but a dreary desert without your smiles and his sallies."
