Three months had elapsed, and Paris was in full carnival. Since the beginning of the year the town had been kept in a state of unusual excitement by the anticipation of a ball, for which the rich and fashionable Countess de M—— had issued invitations to her immense circle of friends and acquaintances. The position of the countess—who, herself the daughter of an illustrious house, and reckoning amongst her ancestors and their alliances more than one sovereign prince and constable of France, had married a man enriched and ennobled by Napoleon—gave her peculiar facilities for collecting around her all that was distinguished and fashionable in Paris, and for blending the various coteries into which political differences, as much as pride of descent on the one hand, and pride of purse on the other, split the higher circles of Parisian society. Her invitations included stiff-necked Legitimists from the dull but dignified streets of St Germain’s faubourg, noble as a La Tremouille or a Montmorency, and still sulking against the monarchy of the 7th August; wealthy parvenus from the Chaussée d’Antin, military nobles of imperial fabrication, Russian princes, English lords, Spanish grandees, diplomatists by the dozen, and a prince or two of the reigning family. Under ordinary circumstances, Madame de M—— might have hesitated to bring together so heterogeneous an assemblage—to have mingled in the same saloons all these conflicting vanities, opinions, and prejudices; but the character of her entertainment removed the inconveniences of such confrontation. It was no ordinary ball or commonplace rout of which the palatial mansion of the countess was upon this occasion to be the scene. She had conceived the bold idea of resuscitating, upon a large scale, an amusement which, in Paris, has long since degenerated into vulgar license and drunken saturnalia. Her entertainment was to be a masquerade, to which no one was to come with uncovered face or in ordinary costume. A mask and a disguise were as essential to obtain entrance, as was the ticket of admission sent to each individual invited, and which was to be delivered up at the door, accompanied by the holder’s engraved visiting-card. This precaution was to guard against the recurrence of an unpleasant incident that had occurred two years previously at a minor entertainment of similar character, when two ingenious professors of legerdemain, better known to the police than to the master of the house, found their way into the ball-room under the convenient covering of dominoes, and departed, before their presence was discovered, carrying with them a varied assortment of watches, purses, and jewellery.

The night of the much-talked-of fête had arrived; the tailors, milliners, and embroiderers, who for a month past had slaved in the service of the invited, had brought home the results of their labours: the fashionable hair-dressers had had a hard day’s work—some hundreds of wreaths and nosegays, which in June would have been beautiful, and in January seemed miraculous, and whose aggregate cost was a comfortable year’s income, had been composed by the tasteful fingers of the Parisian flower-girls. The hour was at hand, and many a fair bosom palpitated with pleasurable anticipations. The hotel of the rich Fatello, as the successful speculator was usually called, had its share of the bustle of preparation; but at last knotty questions of costume were satisfactorily settled, and the ladies committed themselves to the hands of their tirewomen. In his library sat Sigismund Fatello, opening a pile of notes and letters that had accumulated there since afternoon. Some he read and put carefully aside; to others he scarcely vouchsafed a glance; whilst a third class were placed apart for perusal at greater leisure. At last he opened one by whose contents he was strangely moved, for, on reading them, he started and turned pale, as if stung by an adder. Passing his hand over his eyes, as though to clear his vision, he stood up and placed the paper in the very strongest glare of the powerful Carcel lamp illuminating the room. A second time he read, and his agitation visibly increased. Its cause was a small note, containing but four lines, written in a feigned hand. It was an anonymous letter, striking him in his most vulnerable point. Again and again he perused it, striving to recognise the handwriting, or conjecture the author. All his efforts were in vain. Once, inspired by his good genius, he crushed the treacherous paper in his hand, and approached the fireplace to destroy it in the flames. But as he drew near the logs that glowed and crackled on the hearth, his pace became slower and slower, until he finally stood still, smoothed the crumpled paper, and once more devoured its contents. Then he walked several times up and down the apartment with a hurried step. The three months that had elapsed since Arthur de Mellay and Baron Steinfeld had met in the stalls in the opera, had not passed over the head of Fatello without producing a certain change in his appearance. He was thinner and paler, his eyes were more sunken, and a dark line was pencilled beneath them. The change, however, was not such as an indifferent person would notice; it might proceed from many causes—from mental labour, uneasiness, or grief, as well as from bodily disease—the idea of which latter was unlikely to enter the head of a careless observer of his massive frame and features, and of the general appearance of great muscular strength, still remarkable in the ill-favoured financier. Now, however, he was unusually pale and haggard. The letter he still held in his hand had worked upon him like a malevolent charm, hollowing his cheek and wrinkling his brow. For nearly half an hour he continued his monotonous walk, alternately slackening and accelerating his pace. At times he would come to a momentary halt, with the absent air of one absorbed in working out a puzzling problem. At last he opened a secretaire, touched a spring which made a secret drawer fly open, placed in this drawer the letter that had so greatly disturbed him, closed the desk, and, lighting a taper, took the direction of his wife’s sitting-room, in the opposite wing of the hotel.

Madame Fatello and Mademoiselle Sebastiana Gonfalon were equipped for the ball and in readiness to depart. Between the two sisters, in whose ages there was a difference of two years, so strong a resemblance existed that they frequently were taken for twins. Exactly of the same stature, they had the same large dark eyes, abundant hair, and brown tint of skin, and the same mouth, not very small, but beautiful in form, and adorned with teeth of dazzling whiteness. Both had the grace and fascination for which their countrywomen are renowned. The chief difference between them was in expression. Catalina was the more serious of the two: her gravity sometimes verged upon sullenness, and this was especially observable since she had been compelled to a marriage repugnant to her feelings, but which she had lacked energy and courage to resist. Her father would have found it a far less easy task to force Sebastiana to a union opposed to her inclinations. As high-spirited as her sister was irresolute, Mademoiselle Gonfalon was one of those persons whose obstinacy is increased by every attempt at coercion. Laughing and lively amidst all her gay coquetries, there still was a decision in her classically moulded chin and slightly compressed lip, and a something clandestine but resolute in her eye, which a physiognomist would have interpreted as denoting a degree of intelligence and a passionate strength of character denied by nature to her feebler sister. Upon this evening, however, it might have been thought the two young women had exchanged characters. Sebastiana, in general all smiles and sprightliness, was thoughtful and preoccupied, almost anxious; whilst the listless and melancholy Catalina had an unusual appearance of gaiety and animation. Her cheek was flushed, her eyes were brilliant, and she looked repeatedly at a jewelled bijou-watch, as though she would fain have advanced the hour at which she could with propriety make her entrance into Madame de M——’s saloons.

The door opened and Fatello came in. By a powerful exertion of that self-command which he possessed in no ordinary degree, he had banished from his countenance nearly every trace of recent agitation. He was perhaps a shade paler than usual, but his brow was unclouded, and his uncouth countenance was lighted up by the most agreeable smile it could assume.

“So, ladies,” he said, with a liveliness that sat but clumsily upon him, “you are armed for conquest. Accept my compliments on the excellent taste of your costumes. They are really charming. If you are detected, it will hardly be by your dress. Those loose robes and that convenient cowl are the best possible disguises.”

“All the better!” cried Sebastiana. “Nothing like the dear black domino, under which you can be impertinent as you like, with scarce a possibility of discovery. There will be fifty such dresses as ours in the room.”

“No doubt of it,” replied her brother-in-law, thoughtfully. And his piercing green-grey eye scanned the dominoes that shrouded the graceful figures of his wife and her sister. They were of plain black satin; but the art of the maker had contrived to impart elegance to the costume which, of all others, generally possesses it the least. The two dresses were exactly alike, except that Catalina’s was tied at the wrists with lilac ribbons, whilst nothing broke the uniform blackness of her sister’s garb. Black gloves and masks, and two bouquets of choice exotics, the masterpieces of the celebrated bouquetière of the Madeleine boulevard, completed the ladies’ equipment.

“I am sorry,” said Fatello, “to deny myself the pleasure of accompanying you to the Countess’s fête, but I am behindhand with my correspondence, and have received important letters, which I must answer by the morning’s post. My night, a part of it at least, will be passed at the desk instead of in the ball-room.”

There was nothing in this announcement to excite surprise; the tone and manner in which it was made were perfectly natural; but, nevertheless, Sebastiana Gonfalon darted a keen quick glance at her brother-in-law, as though seeking in his words a double meaning or disguised purpose. Madame Fatello showed neither surprise nor disappointment, but, approaching a table, she took from a costly basket of gold filagree, overflowing with cards and invitations, an envelope containing three tickets for the masquerade. Selecting two of them, she threw the third into the basket, and again looked at her watch. At that moment the door opened, and her carriage was announced.
