Just after seven o’clock that same evening young Henfrey and his friend Brock met in the small lounge of the Hotel des Palmiers, a rather obscure little establishment in the Avenue de la Costa, behind the Gardens, much frequented by the habitues of the Rooms who know Monte Carlo and prefer the little place to life at the Paris, the Hermitage, and the Riviera Palace, or the Gallia, up at Beausoleil.

The Palmiers was a place where one met a merry cosmopolitan crowd, but where the cocotte in her bright plumage was absent—an advantage which only the male habitue of Monte Carlo can fully realize. The eternal feminine is always so very much in evidence around the Casino, and the most smartly dressed woman whom one might easily take for the wife of an eminent politician or financier will deplore her bad luck and beg for “a little loan.”

“Well,” said Hugh as his friend came down from his room to the lounge, “I suppose we ought to be going—eh? Dorise said half-past seven, and we’ll just get across to the Metropole in time. Lady Ranscomb is always awfully punctual at home, and I expect she carries out her time-table here.”

The two men put on light overcoats over their dinner-jackets and strolled in the warm dusk across the Gardens and up the Galerie, with its expensive little shops, past the original Ciro’s to the Metropole.

In the big hall they were greeted by a well-preserved, grey-haired Englishwoman, Lady Ranscomb, the widow of old Sir Richard Ranscomb, who had been one of the greatest engineers and contractors of modern times. He had begun life as a small jerry-builder at Golder’s Green, and had ended it a millionaire and a knight. Lady Ranscomb was seated at a little wicker table with her daughter Dorise, a dainty, fair-haired girl with intense blue eyes, who was wearing a rather daring jazzing gown of pale-blue, the scantiness of which a year or two before would have been voted quite beyond the pale for a lady, and yet in our broad-minded to-day, the day of undressing on the stage and in the home, it was nothing more than “smart.”

Mother and daughter greeted the two men enthusiastically, and at Lady Ranscomb’s orders the waiter brought them small glasses of an aperitif.

“We’ve been all day motoring up to the Col di Tenda. Sospel is lovely!” declared Dorise’s mother. “Have you ever been there?” she asked of Brock, who was an habitue of the Riviera.

“Once and only once. I motored from Nice across to Turin,” was his reply. “Yes. It is truly a lovely run there. The Alps are gorgeous. I like San Dalmazzo and the chestnut groves there,” he added. “But the frontiers are annoying. All those restrictions. Nevertheless, the run to Turin is one of the finest I know.”

Presently they rose, and all four walked into the crowded salle-a-manger, where the chatter was in every European language, and the gay crowd were gossiping mostly of their luck or their bad fortune at the tapis vert. At Monte Carlo the talk is always of the run of sequences, the many times the zero-trois has turned up, and of how little one ever wins en plein on thirty-six.

To those who visit “Charley’s Mount” for the first time all this is as Yiddish, but soon he or she, when initiated into the games of roulette and trente-et-quarante, quickly gets bitten by the fever and enters into the spirit of the discussions. They produce their “records”—printed cards in red and black numbers with which they have carefully pricked off the winning numbers with a pin as they have turned up.

The quartette enjoyed a costly but exquisite dinner, chatting and laughing the while.

Both men were friends of Lady Ranscomb and frequent visitors to her fine house in Mount Street. Hugh’s father, a country landowner, had known Sir Richard for many years, while Walter Brock had made the acquaintance of Lady Ranscomb a couple of years ago in connexion with some charity in which she had been interested.

Both were also good friends of Dorise. Both were excellent dancers, and Lady Ranscomb often allowed them to take her daughter to the Grafton, Ciro’s, or the Embassy. Lady Ranscomb was Hugh’s old friend, and he and Dorise having been thrown together a good deal ever since the girl returned from Versailles after finishing her education, it was hardly surprising that the pair should have fallen in love with each other.

As they sat opposite each other that night, the young fellow gazed into her wonderful blue eyes, yet, alas! with a sinking heart. How could they ever marry?

He had about six hundred a year—only just sufficient to live upon in these days. His father had never put him to anything since he left Brasenose, and now on his death he had found that, in order to recover the estate, it was necessary for him to marry Louise Lambert, a girl for whom he had never had a spark of affection. Louise was good-looking, it was true, but could he sacrifice his happiness; could he ever cut himself adrift from Dorise for mercenary motives—in order to get back what was surely by right his inheritance?

Yet, after all, as he again met Dorise’s calm, wide-open eyes, the grim truth arose in his mind, as it ever did, that Lady Ranscomb, even though she had been so kind to him, would never allow her only daughter to marry a man who was not rich. Had not Dorise told him of the sly hints her mother had recently given her regarding a certain very wealthy man named George Sherrard, an eligible bachelor who lived in one of the most expensive flats in Park Lane, and who was being generally sought after by mothers with marriageable daughters. In many cases mothers—and especially young, good-looking widows with daughters “on their hands”—are too prone to try and get rid of them “because my daughter makes me look so old,” as they whisper to their intimates of their own age.

After dinner all four strolled across to the Casino, presenting their yellow cards of admission—the monthly cards granted to those who are approved by the smug-looking, black-coated committee of inspection, who judge by one’s appearance whether one had money to lose.

Dorise soon detached herself from her mother and strolled up the Rooms with Hugh, Lady Ranscomb and Brock following.

None of them intended to play, but they were strolling prior to going to the opera which was beneath the same roof, and for which Lady Ranscomb had tickets.

Suddenly Dorise exclaimed:

“Look over there—at that table in the corner. There’s that remarkable woman they call ‘Mademoiselle of Monte Carlo’!”

Hugh started, and glancing in the direction she indicated saw the handsome woman seated at the table staking her counters quite unconcernedly and entirely absorbed in the game. She was wearing a dead black dress cut slightly low in the neck, but half-bare shoulders, with a string of magnificent Chinese jade beads of that pale apple green so prized by connoisseurs.

Her eyes were fixed upon the revolving wheel, for upon the number sixteen she had just thrown a couple of thousand franc counters. The ball dropped with a sudden click, the croupier announced that number five had won, and at once raked in the two thousand francs among others.

Mademoiselle shrugged her shoulders and smiled faintly. Yvonne Ferad was a born gambler. To her losses came as easily as gains. The Administration knew that—and they also knew how at the little pigeon-hole where counters were exchanged for cheques she came often and handed over big sums in exchange for drafts upon certain banks, both in Paris and in London.

Yet they never worried. Her lucky play attracted others who usually lost. Once, a year before, a Frenchman who occupied a seat next to her daily for a month lost over a quarter of a million sterling, and one night threw himself under the Paris rapide at the long bridge over the Var. But on hearing of it the next day from a croupier Mademoiselle merely shrugged her shoulders, and said:

“I warned him to return to Paris. The fool! It is only what I expected.”

Hugh looked only once across at the mysterious woman whom Dorise had indicated, and then drew her away. As a matter of fact he had no intention that mademoiselle should notice him.

“What do you know of her?” he asked in a casual way when they were on the other side of the great saloon.

“Well, a Frenchman I met in the hotel the day before yesterday told me all sorts of queer stories about her,” replied the girl. “She’s apparently a most weird person, and she has uncanny good luck at the tables. He said that she had won a large fortune during the last couple of years or so.”

Hugh made no remark as to the reason of his visit to the Riviera, for, indeed, he had arrived only the day previously, and she had welcomed him joyously. Little did she dream that her lover had come out from London to see that woman who was declared to be so notorious.

“I noticed her playing this afternoon,” Hugh said a moment later in a quiet reflective tone. “What do the gossips really say about her, Dorise? All this is interesting. But there are so many interesting people here.”

“Well, the man who told me about her was sitting with me outside the Cafe de Paris when she passed across the Place to the Casino. That caused him to make the remarks. He said that her past was obscure. Some people say that she was a Danish opera singer, others declare that she was the daughter of a humble tobacconist in Marseilles, and others assert that she is English. But all agree that she is a clever and very dangerous woman.”

“Why dangerous?” inquired Hugh in surprise.

“Ah! That I don’t know. The man who told me merely hinted at her past career, and added that she was quite a respectable person nowadays in her affluence. But—well——” added the girl with a laugh, “I suppose people gossip about everyone in this place.”

“Who was your informant?” asked her lover, much interested.

“His name is Courtin. I believe he is an official of one of the departments of the Ministry of Justice in Paris. At least somebody said so yesterday.”

“Ah! Then he probably knew more about her than he told you, I expect.”

“No doubt, for he warned my mother and myself against making her acquaintance,” said the girl. “He said she was a most undesirable person.”

At that moment Lady Ranscomb and Walter Brock joined them, whereupon the former exclaimed to her daughter:

“Did you see that woman over there?—still playing—the woman in black and the jade beads, against whom Monsieur Courtin warned us?”

“Yes, mother, I noticed her. I’ve just been telling Hugh about her.”

“A mysterious person—eh?” laughed Hugh with well-affected indifference. “But one never knows who’s who in Monte Carlo.”

“Well, Mademoiselle is apparently something of a mystery,” remarked Brock. “I’ve seen her here before several times. Once, about two years ago, I heard that she was mixed up in a very celebrated criminal case, but exactly what it was the man who told me could not recollect. She is, however, one of the handsomest women in the Rooms.”

“And one of the wealthiest—if report be true,” said Lady Ranscomb.

“She fascinates me,” Dorise declared. “If Monsieur Courtin had not warned us I should most probably have spoken to her.”

“Oh, my dear, you must do no such thing!” cried her mother, horrified. “It was extremely kind of monsieur to give us the hint. He has probably seen how unconventional you are, Dorise.”

And then, as they strolled on into the farther room, the conversation dropped.

“So they’ve heard about Mademoiselle, it seems!” remarked Brock to his friend as they walked back to the Palmiers together in the moonlight after having seen Lady Ranscomb and her daughter to their hotel.

“Yes,” growled the other. “I wish we could get hold of that Monsieur Courtin. He might tell us a bit about her.”

“I doubt if he would. These French officials are always close as oysters.”

“At any rate, I will try and make his acquaintance at the Metropole to-morrow,” Hugh said. “There’s no harm in trying.”

Next morning he called again at the Metropole before the ladies were about, but to his chagrin, he learnt from the blue-and-gold concierge that Monsieur Courtin, of the Ministry of Justice, had left at ten-fifteen o’clock on the previous night by the rapide for Paris. He had been recalled urgently, and a special coupe-lit had been reserved for him from Ventimiglia.

That day Hugh Henfrey wandered about the well-kept palm-lined gardens with their great beds of geraniums, carnations and roses. Brock had accepted the invitation of a bald-headed London stock-broker he knew to motor over to lunch and tennis at the Beau Site, at Cannes, while Dorise and her mother had gone with some people to lunch at the Reserve at Beaulieu, one of the best and yet least pretentious restaurants in all Europe, only equalled perhaps by Capsa’s, in Bucharest.

“Ah! If she would only tell!” Hugh muttered fiercely to himself as he walked alone and self-absorbed. His footsteps led him out of Monte Carlo and up the winding road which runs to La Turbie, above the beautiful bay. Ever and anon powerful cars climbing the hill smothered him in white dust, yet he heeded them not. He was too full of thought.

“Ah!” he kept on repeating to himself. “If she would only tell the truth—if she would only tell!”

Hugh Henfrey had not travelled to Monte Carlo without much careful reflection and many hours of wakefulness. He intended to clear up the mystery of his father’s death—and more, the reason of that strange incomprehensible will which was intended to wed him to Louise.

At four o’clock that afternoon he entered the Rooms to gain another surreptitious look at Mademoiselle. Yes! She was there, still playing on as imperturbably as ever, with that half-suppressed sinister smile always upon her full red lips.

Sight of her aroused his fury. Was that smile really intended for himself? People said she was a sphinx, but he drew his breath, and when outside the Casino again in the warm sunshine he halted upon the broad red-carpeted steps and beneath his breath said in a hard, determined tone:

“Gad! She shall tell me! She shall! I’ll compel her to speak—to tell me the truth—or—or——!”

That evening he wrote a note to Dorise explaining to her that he was not feeling very well and excusing himself from going round to the hotel. This he sent by hand to the Metropole.

Brock did not turn up at dinner. Indeed, he did not expect his friend back till late. So he ate his meal alone, and then went out to the Cafe de Paris, where for an hour he sat upon the terrasse smoking and listening to the weird music of the red-coated orchestra of Roumanian gipsies.

All the evening, indeed, he idled, chatting with men and women he knew. Carmen was being given at the Opera opposite, but though he loved music he had no heart to go. The one thought obsessing him was of the handsome and fascinating woman who was such a mystery to all.

At eleven o’clock he returned to the cafe and took a seat on the terrasse in a dark corner, in such a position that he could see anyone who entered or left the Casino. For half an hour he watched the people passing to and fro. At last, in a long jade-green coat, Mademoiselle emerged alone, and, crossing the gardens, made her way leisurely home on foot, as was her habit. Monte Carlo is not a large place, therefore there is little use for taxis.

When she was out of sight, he called the waiter to bring him a liqueur of old cognac, which he sipped, and then lit another cigarette. When he had finished it he drained the little glass, and rising, strolled in the direction the woman of mystery had taken.

A walk of ten minutes brought him to the iron gates of a great white villa, over the high walls of which climbing roses and geraniums and jasmine ran riot. The night air was heavy with their perfume. He opened the side gate and walked up the gravelled drive to the terrace whereon stood the house, commanding a wonderful view of the moon-lit Mediterranean and the far-off mountains of Italy.

His ring at the door was answered by a staid elderly Italian manservant.

“I believe Mademoiselle is at home,” Hugh said in French. “I desire to see her, and also to apologize for the lateness of the hour. My visit is one of urgency.”

“Mademoiselle sees nobody except by appointment,” was the man’s polite but firm reply.

“I think she will see me if you give her this card,” answered Hugh in a strained, unusual voice.

The man took it hesitatingly, glanced at it, placed it upon a silver salver, and, leaving the visitor standing on the mat, passed through the glass swing-doors into the house.

For some moments the servant did not reappear.

Hugh, standing there, entertained just a faint suspicion that he heard a woman’s shrill exclamation of surprise. And that sound emboldened him.

At last, after an age it seemed, the man returned, saying:

“Mademoiselle will see you, Monsieur. Please come this way.”

He left his hat and stick and followed the man along a corridor richly carpeted in red to a door on the opposite side of the house, which the servant threw open and announced the visitor.

Mademoiselle had risen to receive him. Her countenance was, Hugh saw, blanched almost to the lips. Her black dress caused her pallor to be more apparent.

“Well, sir? Pray what do you mean by resorting to this ruse in order to see me? Who are you?” she demanded.

Hugh was silent for a moment. Then in a hard voice he said:

“I am the son of the dead man whose card is in your hands, Mademoiselle! And I am here to ask you a few questions!”

The handsome woman smiled sarcastically and shrugged her half-bare shoulders, her fingers trembling with her jade beads.

“Oh! Your father is dead—is he?” she asked with an air of indifference.

“Yes. He is dead,” Hugh said meaningly, as he glanced around the luxurious little room with its soft rose-shaded lights and pale-blue and gold decorations. On her right as she stood were long French windows which opened on to a balcony. One of the windows stood ajar, and it was apparent that when he had called she had been seated in the long wicker chair outside enjoying the balmy moonlight after the stifling atmosphere of the Rooms.

“And, Mademoiselle,” he went on, “I happen to be aware that you knew my father, and—that you are cognizant of certain facts concerning his mysterious end.”

“I!” she cried, raising her voice in sudden indignation. “What on earth do you mean?” She spoke in perfect English, though he had hitherto spoken in French.

“I mean, Mademoiselle, that I intend to know the truth,” said Hugh, fixing his eyes determinedly upon hers. “I am here to learn it from your lips.”

“You must be mad!” cried the woman. “I know nothing of the affair. You are mistaken!”

“Do you, then, deny that you have ever met a man named Charles Benton?” demanded the young fellow, raising his voice. “Perhaps, however, that is a bitter memory, Mademoiselle—eh?”

The strikingly handsome woman pursed her lips. There was a strange look in her eyes. For several moments she did not speak. It was clear that the sudden appearance of the dead man’s son had utterly unnerved her. What could he know concerning Charles Benton? How much of the affair did he suspect?

“I have met many people, Mr.—er—Mr. Henfrey,” she replied quietly at last. “I may have met somebody named Benton.”

“Ah! I see,” the young man said. “It is a memory that you do not wish to recall any more than that of my dead father.”

“Your father was a good man. Benton was not.”

“Ah! Then you admit knowing both of them, Mademoiselle,” cried Hugh quickly.

“Yes. I—well—I may as well admit it! Why, indeed, should I seek to hide the truth—from you,” she said in a changed voice. “Pardon me. I was very upset at receiving the card. Pardon me—will you not?”

“I will not, unless you tell me the truth concerning my father’s death and his iniquitous will left concerning myself. I am here to ascertain that, Mademoiselle,” he said in a hard voice.

“And if I tell you—what then?” she asked with knit brows.

“If you tell me, then I am prepared to promise you on oath secrecy concerning yourself—provided you allow me to punish those who are responsible. Remember, my father died by foul means. And you know it!”

The woman faced him boldly, but she was very pale.

“So that is a promise?” she asked. “You will protect me—you will be silent regarding me—you swear to be so—if—if I tell you something. I repeat that your father was a good man. I held him in the highest esteem, and—and—after all—it is but right that you, his son, should know the truth.”

“Thank you Mademoiselle. I will protect you if you will only reveal to me the devilish plot which resulted in his untimely end,” Hugh assured her.

Again she knit her brows and reflected for a few moments. Then in a low, intense, unnatural voice she said:

“Listen, Mr. Henfrey. I feel that, after all, my conscience would be relieved if I revealed to you the truth. First—well, it is no use denying the fact that your father was not exactly the man you and his friends believed him to be. He led a strange dual existence, and I will disclose to you one or two facts concerning his untimely end which will show you how cleverly devised and how cunning was the plot—how——”

At that instant Hugh was startled by a bright flash outside the half-open window, a loud report, followed by a woman’s shrill shriek of pain.

Then, next moment, ere he could rush forward to save her, Mademoiselle, with the truth upon her lips unuttered, staggered and fell back heavily upon the carpet!
