Vanno stood without moving for some minutes, when Mary had gone. She had forbidden him to follow, but it was not her command which held him back. It was the command laid upon him by himself. In a light merciless as the crude glare of electricity he saw himself standing stricken, a fool who had done an unforgivable thing, a clumsy and brutal wretch who had broken a crystal vase in a sanctuary. For the blinding light showed him a new image of Mary, even as she had suddenly revealed herself to Hannaford: a perfectly innocent creature whose ways were strange as a dryad's way would be strange if transplanted from her forests into the most sophisticated colony in Europe.

Something in Vanno which knew, because it felt, had always pronounced her guiltless; but all of him that was modern and worldly had told him to distrust her. Now he was like a judge who has condemned a prisoner on circumstantial evidence, to find out the victim's innocence after the execution.

Standing there on the bridge, the dance-music troubled the current of his thoughts, rising to the surface of his mind, though he heard it without listening, like the teasing bubbles of a spring through deep water. Though he tried, he could not fully analyze his own feelings; yet he was sharply conscious of those two conflicting sides of his nature which Angelo saw, and he could almost hear them arguing together. The part of him that was aristocrat and ascetic excused itself, asking what he could have done, better than he had done? Had he not broken his resolve for a good motive and for the girl's sake, not his own? Had he begged anything of her for himself? Ought she not to have understood that though he loved her, he could not ask her to be his wife unless or until she could prove herself worthy—not of him—but of a name and of traditions honoured in history? Ought she not to have trusted him, and seen that he was resisting temptation, not yielding to it, when he implored her to take his help and friendship?

Already Angelo had disappointed their father, by marrying a girl of whom no one knew anything except her beauty and talent as an artist. Marie Gaunt had come to Rome to paint the portrait of a fashionable woman; had been "taken up" by other mondaines; and Angelo, meeting her at a dinner, had fallen in love with and followed her to Dresden, where she lived and had made her reputation as an artist. In spite of the Duke's objections they had married; and Vanno, who was his father's favourite, surely owed some duty to the old man who loved him. At worst, Marie Gaunt the artist had in no way laid herself open to gossip. According to what friends had written from Rome, she was more than discreet, demure as a Puritan maiden, and the elderly chaperon who travelled with her was a dragon of virtue. With this girl whom Vanno had met at Monte Carlo it was different. She was not discreet. Whatever else she might be, she was not Puritan. She was gossiped about on all sides, and gayly fed the fire of gossip by appearing in startling dresses, by doing startling things, and picking up extraordinary acquaintances. Even as far away as Mentone and Nice she was talked about. Two women had started some story about her travelling to Paris with a French artist; and the man himself, who had arrived since, had made a fool of himself at the Casino, and apparently tried to blackmail her. She was said to have given him money. No love, no matter how great, could justify Prince Giovanni Della Robbia in making such a girl his wife while uncertain of the truth which underlay her amazing eccentricities, and the gossip which followed her everywhere, like a dog that barked at her heels.

This was what one side of him protested anxiously to the other side, which in turn raged against it and its cold plausibilities. The side which was all passion and romance and high chivalry lashed its enemy with contempt, and evil epithets of which the hardest to bear was "prig." For no man can endure being thought a prig, even by himself.

"You, who said that her soul was meant for yours, and the next moment distrusted it!" he reproached himself in bitterness. "What a fool—what a hypocrite! If you've known her since the beginning of things, you should have known by instinct what she was, down under the surface frivolities and foolishnesses, mistakes any untaught girl might make."

This Vanno, who was all man and not prince, said that no punishment could be too severe for one who doubts where he loves. He saw himself justly punished now, by learning Mary's truth through her noble indignation. Because he had waited for this proof he acknowledged that he had sinned beyond most women's pardon; yet he meant to win hers. He cared more for her than before, and determined that he would never give her up; yet all the while that other, worldly Vanno, who was prince as well as man, held stiffly back. How could one whose small knowledge of women good and bad came mostly through hearsay be sure of a woman?

His one boyish venture in love he saw now had been in shallow water; but it had not tended to strengthen his faith in the innate nobility of women. On the contrary, it had shown him that a woman who seemed sweet and loving could be hard and calculating, even mercenary. Innocence being a charming pose, why should it not be adopted by the cleverest actresses, professional sirens, specialists in enchantment, who wished to be admired by all men, even men for whom they cared nothing? How could he tell even now that this girl was not a clever actress who judged him well and planned to lead him on?

So he asked himself questions, and answered in rage, only to begin again, fiercely breaking down one set of arguments and building up another.

It was the arrival of Dodo Wardropp with Dom Ferdinand on the bridge which drove him away and out of himself sufficiently to bid his host and hostess good-night.

When the motor launch had taken him ashore, the impulse was very strong in him to go up to Roquebrune and tell the curÉ what had happened. He knew that his friend kept a light burning all night in a window, and he could see it, as Mary had seen it, sending out its message for any who needed help. Yet what good could come of talking to one who had never met the girl? Fate had kept the two apart, for some reason, and Vanno could but consult his own heart. Its counsel was to write to Mary, explaining all those things that she had not let him explain in words.

This matter of explanation seemed easier than it proved. Letter after letter had to be torn up before Vanno was able to express on paper anything at all which she might understand, which might soften her to forgiveness. Even then he was dissatisfied; but something had to stand, something had to go. "Write me at least one line," he ended, "if only to say that you know I did not mean to insult you, in the way you thought when you left me."

Mary was still "Miss M. Grant" to him, and so he addressed his letter. Dawn had put the stars to sleep when he sealed the envelope, and he had to wait for a reasonable hour before sending to her room; but he did not go to bed, or try to sleep.

"Christmas!" he said to himself, aloud. "The day of peace on earth and good will toward men. If she remembers, can she refuse to forgive me?"

At half-past eight he thought it might be taken for granted that she was awake. "Don't ask for an answer," he told the young waiter to whom he gave his sealed envelope, and the lace scarf which Mary had left in his hands. "Say only that you're not sure whether there is an answer or not, and you will wait to see."

Vanno had hoped the servant might be away a long time, as delay would mean that Mary was taking time to think, and writing a reply. But in less than ten minutes the man was at the door again.

"The lady was in, and when I gave her the scarf and letter, asked me who had sent them," was the report. "I told her it was his Highness the Roman Prince, staying in the hotel. Then she said, 'This scarf is mine, but the letter must have been sent by mistake, as I do not know his Highness.' So I have brought it back, as the lady desired. I hope I have done right?"

"Quite right, thank you," Vanno returned mechanically, and took his own letter. His ears tingled as though Mary's little fingers had boxed them. If she had but known, she was more than revenged upon him for the snub which had clouded her first dinner in the restaurant of the HÔtel de Paris.

For a moment Vanno was intensely angry, because she had dared to humiliate him in the eyes of a servant; but by and by, when his ears stopped tingling, he told himself that he deserved even this. He respected her all the more, and no longer feared that she might be a clever actress trying to lead him on. A woman who wished to attract a man would not use so sharp a weapon.

Still, Vanno had no thought of giving up. If she would not read his explanation she must hear it, and justify him in one way, even if she would not forgive. He hoped to see her at luncheon time, but she did not come into the restaurant. Again, at dinner she was absent. A merry little Christmas party of four sat at her table: an English duke and duchess, a great Russian dancer, a general of world-wide fame.

"Where is the lady who usually sits opposite?" he asked of his waiter, draining his voice of all expression. "Is she away for Christmas?"

"She is away altogether," answered the waiter. "She left before luncheon."

"Left altogether—left before luncheon!" Vanno echoed, almost stupidly, forgetting to appear indifferent.

"I believe she is still in Monte Carlo," the man went on, delighted to give information. "I do not know where, but I can no doubt find out for your Highness."

"No, thanks, I won't trouble you," Vanno replied hurriedly. He would not learn her whereabouts from a servant, but would find out for himself. Where could she be? To whom could she have gone? The uncertainty was unbearable. If it were true that she was still in Monte Carlo, she would probably be in the Casino this evening. Vanno had not gone there often, after the first night or two, for he hated to see Mary in the Rooms alone, playing a game which attracted crowds, and caused people of all sorts to talk about her. Now, however, he finished his dinner quickly, and went immediately to the Casino.

It was just nine o'clock, and though it was Christmas the crowd was as great as ever, even greater than he had seen it before. Vanno walked through the Salle Schmidt, where Mary usually played, stopping at each table long enough to make sure that she was not there. Then he passed on into the newer rooms lit by those hanging lights which Mary had thought like diamond necklaces of giantesses. The three life-size figures of the eccentric yet decorative picture, nicknamed "The Disgraces," seemed to follow him mockingly with langorous eyes, whispering to each other, "Here comes a fool who does not understand women."

Mary was not playing at any of the tables in these rooms; but there was hope still. The Sporting Club had now opened for the season, and it was more fashionable at night even than the Casino. Vanno had walked through once or twice, after midnight when the Casino had shut, and found there a scene of great beauty and animation: the prettiest women in Monte Carlo, wearing wonderful dresses and jewels, and famous men of nearly all the countries of the world, princes and politicians, great soldiers and grave judges, and even one or two travelling kings. It was very likely that Miss Grant would have gone on to the Sporting Club, after dinner with friends on Christmas Day.

He went across the road and a little down the hill, where the white clubhouse owned by the Casino blazed with light. But as he reached it, Dick Carleton dashed through the door, began running down the steps, and almost cannoned into him.

"Beg pardon, Prince," he exclaimed. "I've just been told that a friend of mine's losing like the dickens, in the Cercle PrivÉ, and I'm going to dart across and take out my subscription. I've never done it yet. But it will be worth the hundred francs to stop her, if I can."

"Is it Miss Grant?" Vanno did not deliberately put the question, but heard himself asking it.

"Why, yes it is," Carleton admitted. "Have you been in—have you seen her?"

"No. But I felt somehow that you were speaking of Miss Grant."

"I thought you scarcely knew her," Dick caught him up, jealously.

"You are right. I—scarcely know her. But one has intuitions sometimes. I must have had one then. So—she is losing? I heard she had wonderful luck."

"She has had, up till now. Seemed as if she couldn't lose. Christmas night, too! Isn't it a shame?" And Dick was off, hatless, in evening dress without an overcoat. Vanno stood still in front of the Sporting Club for a moment, watching the slim boyish figure go striding up the hill. A liveried porter, seeing the Prince at the foot of the steps, obsequiously opened the door, but Vanno made a sign that he did not wish to enter. As soon as Dick had disappeared, Vanno followed him.

As he went seldom to the Casino, he had not taken a subscription to the newest rooms, or Cercle PrivÉ, where the price of admission is a hundred francs. These rooms are for ardent gamblers who dislike playing in a crowd, and Vanno, who had not felt inclined to play at all, scarcely remembered their existence. Now he bought a ticket, however, and having written his name upon it, followed Carleton at a little distance, to a door at the far end of the trente et quarante rooms. His heart was beating heavily, for in a few minutes he would perhaps know to whom Mary had gone when she left the HÔtel de Paris.
