Arthur went back to London next day.

Susie felt it impossible any longer to stay in the deserted studio, and accepted a friend's invitation to spend the winter in Italy. The good Dr Porho?t remained in Paris with his books and his occult studies.

Susie travelled slowly through Tuscany and Umbria. Margaret had not written to her, and Susie, on leaving Paris, had sent her friend's belongings to an address from which she knew they would eventually be forwarded. She could not bring herself to write. In answer to a note announcing her change of plans, Arthur wrote briefly that he had much work to do and was delivering a new course of lectures at St. Luke's; he had lately been appointed visiting surgeon to another hospital, and his private practice was increasing. He did not mention Margaret. His letter was abrupt, formal, and constrained. Susie, reading it for the tenth time, could make little of it. She saw that he wrote only from civility, without interest; and there was nothing to indicate his state of mind. Susie and her companion had made up their minds to pass some weeks in Rome; and here, to her astonishment, Susie had news of Haddo and his wife. It appeared that they had spent some time there, and the little English circle was talking still of their eccentricities. They travelled in some state, with a courier and a suite of servants; they had taken a carriage and were in the habit of driving every afternoon on the Pincio. Haddo had excited attention by the extravagance of his costume, and Margaret by her beauty; she was to be seen in her box at the opera every night, and her diamonds were the envy of all beholders. Though people had laughed a good deal at Haddo's pretentiousness, and been exasperated by his arrogance, they could not fail to be impressed by his obvious wealth. But finally the pair had disappeared suddenly without saying a word to anybody. A good many bills remained unpaid, but these, Susie learnt, had been settled later. It was reported that they were now in Monte Carlo.

'Did they seem happy?' Susie asked the gossiping friend who gave her this scanty information.

'I think so. After all, Mrs Haddo has almost everything that a woman can want, riches, beauty, nice clothes, jewels. She would be very unreasonable not to be happy.'

Susie had meant to pass the later spring on the Riviera, but when she heard that the Haddos were there, she hesitated. She did not want to run the risk of seeing them, and yet she had a keen desire to find out exactly how things were going. Curiosity and distaste struggled in her mind, but curiosity won; and she persuaded her friend to go to Monte Carlo instead of to Beaulieu. At first Susie did not see the Haddos; but rumour was already much occupied with them, and she had only to keep her ears open. In that strange place, where all that is extravagant and evil, all that is morbid, insane, and fantastic, is gathered together, the Haddos were in fit company. They were notorious for their assiduity at the tables and for their luck, for the dinners and suppers they gave at places frequented by the very opulent, and for their eccentric appearance. It was a complex picture that Susie put together from the scraps of information she collected. After two or three days she saw them at the tables, but they were so absorbed in their game that she felt quite safe from discovery. Margaret was playing, but Haddo stood behind her and directed her movements. Their faces were extraordinarily intent. Susie fixed her attention on Margaret, for in what she had heard of her she had been quite unable to recognize the girl who had been her friend. And what struck her most now was that there was in Margaret's expression a singular likeness to Haddo's. Notwithstanding her exquisite beauty, she had a curiously vicious look, which suggested that somehow she saw literally with Oliver's eyes. They had won great sums that evening, and many persons watched them. It appeared that they played always in this fashion, Margaret putting on the stakes and Haddo telling her what to do and when to stop. Susie heard two Frenchmen talking of them. She listened with all her ears. She flushed as she heard one of them make an observation about Margaret which was more than coarse. The other laughed.

'It is incredible,' he said.

'I assure you it's true. They have been married six months, and she is still only his wife in name. The superstitious through all the ages have believed in the power of virginity, and the Church has made use of the idea for its own ends. The man uses her simply as a mascot.'

The men laughed, and their conversation proceeded so grossly that Susie's cheeks burned. But what she had heard made her look at Margaret more closely still. She was radiant. Susie could not deny that something had come to her that gave a new, enigmatic savour to her beauty. She was dressed more gorgeously than Susie's fastidious taste would have permitted; and her diamonds, splendid in themselves, were too magnificent for the occasion. At last, sweeping up the money, Haddo touched her on the shoulder, and she rose. Behind her was standing a painted woman of notorious disreputability. Susie was astonished to see Margaret smile and nod as she passed her.

Susie learnt that the Haddos had a suite of rooms at the most expensive of the hotels. They lived in a whirl of gaiety. They knew few English except those whose reputations were damaged, but seemed to prefer the society of those foreigners whose wealth and eccentricities made them the cynosure of that little world. Afterwards, she often saw them, in company of Russian Grand-Dukes and their mistresses, of South American women with prodigious diamonds, of noble gamblers and great ladies of doubtful fame, of strange men overdressed and scented. Rumour was increasingly busy with them. Margaret moved among all those queer people with a cold mysteriousness that excited the curiosity of the sated idlers. The suggestion which Susie overheard was repeated more circumstantially. But to this was joined presently the report of orgies that were enacted in the darkened sitting-room of the hotel, when all that was noble and vicious in Monte Carlo was present. Oliver's eccentric imagination invented whimsical festivities. He had a passion for disguise, and he gave a fancy-dress party of which fabulous stories were told. He sought to revive the mystical ceremonies of old religions, and it was reported that horrible rites had been performed in the garden of the villa, under the shining moon, in imitation of those he had seen in Eastern places. It was said that Haddo had magical powers of extraordinary character, and the tired imagination of those pleasure-seekers was tickled by his talk of black art. Some even asserted that the blasphemous ceremonies of the Black Mass had been celebrated in the house of a Polish Prince. People babbled of satanism and of necromancy. Haddo was thought to be immersed in occult studies for the performance of a magical operation; and some said that he was occupied with the Magnum Opus, the greatest and most fantastic of alchemical experiments. Gradually these stories were narrowed down to the monstrous assertion that he was attempting to create living beings. He had explained at length to somebody that magical receipts existed for the manufacture of _homunculi_.

Haddo was known generally by the name he was pleased to give himself. The Brother of the Shadow; but most people used it in derision, for it contrasted absurdly with his astonishing bulk. They were amused or outraged by his vanity, but they could not help talking about him, and Susie knew well enough by now that nothing pleased him more. His exploits as a lion-hunter were well known, and it was reported that human blood was on his hands. It was soon discovered that he had a queer power over animals, so that in his presence they were seized with unaccountable terror. He succeeded in surrounding himself with an atmosphere of the fabulous, and nothing that was told of him was too extravagant for belief. But unpleasant stories were circulated also, and someone related that he had been turned out of a club in Vienna for cheating at cards. He played many games, but here, as at Oxford, it was found that he was an unscrupulous opponent. And those old rumours followed him that he took strange drugs. He was supposed to have odious vices, and people whispered to one another of scandals that had been with difficulty suppressed. No one quite understood on what terms he was with his wife, and it was vaguely asserted that he was at times brutally cruel to her. Susie's heart sank when she heard this; but on the few occasions upon which she caught sight of Margaret, she seemed in the highest spirits. One story inexpressibly shocked her. After lunching at some restaurant, Haddo gave a bad louis among the money with which he paid the bill, and there was a disgraceful altercation with the waiter. He refused to change the coin till a policeman was brought in. His guests were furious, and several took the first opportunity to cut him dead. One of those present narrated the scene to Susie, and she was told that Margaret laughed unconcernedly with her neighbour while the sordid quarrel was proceeding. The man's blood was as good as his fortune was substantial, but it seemed to please him to behave like an adventurer. The incident was soon common property, and gradually the Haddos found themselves cold-shouldered. The persons with whom they mostly consorted had reputations too delicate to stand the glare of publicity which shone upon all who were connected with him, and the suggestion of police had thrown a shudder down many a spine. What had happened in Rome happened here again: they suddenly disappeared.

Susie had not been in London for some time, and as the spring advanced she remembered that her friends would be glad to see her. It would be charming to spend a few weeks there with an adequate income; for its pleasures had hitherto been closed to her, and she looked forward to her visit as if it were to a foreign city. But though she would not confess it to herself, her desire to see Arthur was the strongest of her motives. Time and absence had deadened a little the intensity of her feelings, and she could afford to acknowledge that she regarded him with very great affection. She knew that he would never care for her, but she was content to be his friend. She could think of him without pain.

Susie stayed in Paris for three weeks to buy some of the clothes which she asserted were now her only pleasure in life, and then went to London.

She wrote to Arthur, and he invited her at once to lunch with him at a restaurant. She was vexed, for she felt they could have spoken more freely in his own house; but as soon as she saw him, she realized that he had chosen their meeting-place deliberately. The crowd of people that surrounded them, the gaiety, the playing of the band, prevented any intimacy of conversation. They were forced to talk of commonplaces. Susie was positively terrified at the change that had taken place in him. He looked ten years older; he had lost flesh, and his hair was sprinkled with white. His face was extraordinarily drawn, and his eyes were weary from lack of sleep. But what most struck her was the change in his expression. The look of pain which she had seen on his face that last evening in the studio was now become settled, so that it altered the lines of his countenance. It was harrowing to look at him. He was more silent than ever, and when he spoke it was in a strange low voice that seemed to come from a long way off. To be with him made Susie curiously uneasy, for there was a strenuousness in him which deprived his manner of all repose. One of the things that had pleased her in him formerly was the tranquillity which gave one the impression that here was a man who could be relied on in difficulties. At first she could not understand exactly what had happened, but in a moment saw that he was making an unceasing effort at self-control. He was never free from suffering and he was constantly on the alert to prevent anyone from seeing it. The strain gave him a peculiar restlessness.

But he was gentler than he had ever been before. He seemed genuinely glad to see her and asked about her travels with interest. Susie led him to talk of himself, and he spoke willingly enough of his daily round. He was earning a good deal of money, and his professional reputation was making steady progress. He worked hard. Besides his duties at the two hospitals with which he was now connected, his teaching, and his private practice, he had read of late one or two papers before scientific bodies, and was editing a large work on surgery.

'How on earth can you find time to do so much?' asked Susie.

'I can do with less sleep than I used,' he answered. 'It almost doubles my working-day.'

He stopped abruptly and looked down. His remark had given accidentally some hint at the inner life which he was striving to conceal. Susie knew that her suspicion was well-founded. She thought of the long hours he lay awake, trying in vain to drive from his mind the agony that tortured him, and the short intervals of troubled sleep. She knew that he delayed as long as possible the fatal moment of going to bed, and welcomed the first light of day, which gave him an excuse for getting up. And because he knew that he had divulged the truth he was embarrassed. They sat in awkward silence. To Susie, the tragic figure in front of her was singularly impressive amid that lighthearted throng: all about them happy persons were enjoying the good things of life, talking, laughing, and making merry. She wondered what refinement of self-torture had driven him to choose that place to come to. He must hate it.

When they finished luncheon, Susie took her courage in both hands.

'Won't you come back to my rooms for half an hour? We can't talk here.'

He made an instinctive motion of withdrawal, as though he sought to escape. He did not answer immediately, and she insisted.

'You have nothing to do for an hour, and there are many things I want to speak to you abou............
