When Haddo entered, Arthur, standing with his back to the fireplace, motioned him to sit down.

'What can I do for you?' he asked coldly.

'I have not come to avail myself of your surgical skill, my dear Burdon,'

smiled Haddo, as he fell ponderously into an armchair.

'So I imagined.'

'You perspicacity amazes me. I surmise that it is to you I owe this amusing citation which was served on me yesterday.'

'I allowed you to come in so that I might tell you I will have no communication with you except through my solicitors.'

'My dear fellow, why do you treat me with such discourtesy? It is true that you have deprived me of the wife of my bosom, but you might at least so far respect my marital rights as to use me civilly.'

'My patience is not as good as it was,' answered Arthur, 'I venture to remind you that once before I lost my temper with you, and the result you must have found unpleasant.'

'I should have thought you regretted that incident by now, O Burdon,'

answered Haddo, entirely unabashed.

'My time is very short,' said Arthur.

'Then I will get to my business without delay. I thought it might interest you to know that I propose to bring a counter-pet.i.tion against my wife, and I shall make you co-respondent.'

'You infamous blackguard!' cried Arthur furiously. 'You know as well as I do that your wife is above suspicion.'

'I know that she left my hotel in your company, and has been living since under your protection.'

Arthur grew livid with rage. He could hardly restrain himself from knocking the man down. He gave a short laugh.

'You can do what you like. I'm really not frightened.'

'The innocent are so very incautious. I a.s.sure you that I can make a good enough story to ruin your career and force you to resign your appointments at the various hospitals you honour with your attention.'

'You forget that the case will not be tried in open court,' said Arthur.

Haddo looked at him steadily. He did not answer for a moment.

'You're quite right,' he said at last, with a little smile. 'I had forgotten that.'

'Then I need not detain you longer.'

Oliver Haddo got up. He pa.s.sed his hand reflectively over his huge face.

Arthur watched him with scornful eyes. He touched a bell, and the servant at once appeared.

'Show this gentleman out.'

Not in the least disconcerted, Haddo strolled calmly to the door.

Arthur gave a sigh of relief, for he concluded that Haddo would not show fight. His solicitor indeed had already a.s.sured him that Oliver would not venture to defend the case.

Margaret seemed gradually to take more interest in the proceedings, and she was full of eagerness to be set free. She did not shrink from the unpleasant ordeal of a trial. She could talk of Haddo with composure. Her friends were able to persuade themselves that in a little while she would be her old self again, for she was growing stronger and more cheerful; her charming laughter rang through the little house as it had been used to do in the Paris studio. The case was to come on at the end of July, before the long vacation, and Susie had agreed to take Margaret abroad as soon as it was done.

But presently a change came over her. As the day of the trial drew nearer, Margaret became excited and disturbed; her gaiety deserted her, and she fell into long, moody silences. To some extent this was comprehensible, for she would have to disclose to callous ears the most intimate details of her married life; but at last her nervousness grew so marked that Susie could no longer ascribe it to natural causes. She thought it necessary to write to Arthur about it.

My Dear Arthur:

I don't know what to make of Margaret, and I wish you would come down and see her. The good-humour which I have noticed in her of late has given way to a curious irritability. She is so restless that she cannot keep still for a moment. Even when she is sitting down her body moves in a manner that is almost convulsive. I am beginning to think that the strain from which she suffered is bringing on some nervous disease, and I am really alarmed. She walks about the house in a peculiarly aimless manner, up and down the stairs, in and out of the garden. She has grown suddenly much more silent, and the look has come back to her eyes which they had when first we brought her down here. When I beg her to tell me what is troubling her, she says: 'I'm afraid that something is going to happen.'

She will not or cannot explain what she means. The last few weeks have set my own nerves on edge, so that I do not know how much of what I observe is real, and how much is due to my fancy; but I wish you would come and put a little courage into me. The oddness of it all is making me uneasy, and I am seized with preposterous terrors. I don't know what there is in Haddo that inspires me with this unaccountable dread. He is always present to my thoughts. I seem to see his dreadful eyes and his cold, sensual smile. I wake up at night, my heart beating furiously, with the consciousness that something quite awful has happened.

Oh, I wish the trial were over, and that we were happy in Germany.

Yours ever SUSAN BOYD

Susie took a certain pride in her common sense, and it was humiliating to find that her nerves could be so distraught. She was worried and unhappy.

It had not been easy to take Margaret back to her bosom as if nothing had happened. Susie was human; and, though she did ten times more than could be expected of her, she could not resist a feeling of irritation that Arthur sacrificed her so calmly. He had no room for other thoughts, and it seemed quite natural to him that she should devote herself entirely to Margaret's welfare.

Susie walked some way along the road to post this letter and then went to her room. It was a wonderful night, starry and calm, and the silence was like balm to her troubles. She sat at the window for a long time, and at last, feeling more tranquil, went to bed. She slept more soundly than she had done for many days. When she awoke the sun was streaming into her room, and she gave a deep sigh of delight. She could see trees from her bed, and blue sky. All her troubles seemed easy to bear when the world was so beautiful, and she was ready to laugh at the fears that had so affected her.

She got up, put on a dressing-gown, and went to Margaret's room. It was empty. The bed had not been slept in. On the pillow was a note.

It's no good; I can't help myself. I've gone back to him. Don't trouble about me any more. It's quite hopeless and useless.

M

Susie gave a little gasp. Her first thought was for Arthur, and she uttered a wail of sorrow because he must be cast again into the agony of desolation. Once more she had to break the dreadful news. She dressed hurriedly and ate some breakfast. There was no train till nearly eleven, and she had to bear her impatience as best she could. At last it was time to start, and she put on her gloves. At that moment the door was opened, and Arthur came in.

She gave a cry of terror and turned pale.

'I was just coming to London to see you,' she faltered. 'How did you find out?'

'Haddo sent me a box of chocolates early this morning with a card on which was written: _I think the odd trick is mine_.'

This cruel vindictiveness, joined with a schoolboy love of taunting the vanquished foe, was very characteristic. Susie gave Arthur Burdon the note which she had found in Margaret's room. He read it and then thought for a long time.

'I'm afraid she's right,' he said at length. 'It seems quite hopeless.

The man has some power over her which we can't counteract.'

Susie wondered whether his strong scepticism was failing at last.

She could not withstand her own feeling that there was something preternatural about the hold that Oliver had over Margaret. She had no shadow of a doubt that he was able to affect his wife even at a distance, and was convinced now that the restlessness of the last few days was due to this mysterious power. He had been at work in some strange way, and Margaret had been aware of it. At length she could not resist and had gone to him instinctively: her will was as little concerned as when a chip of steel flies to a magnet.

'I cannot find it in my heart now to blame her for anything she has done,' said Susie. 'I think she is the victim of a most lamentable fate.

I can't help it. I must believe that he was able to cast a spell on her; and to that is due all that has happened. I have only pity for her great misfortunes.'

'Has it occurred to you what will happen when she is back in Haddo's hands?' cried Arthur. 'You know as well as I do how revengeful he is and how hatefully cruel. My heart bleeds when I think of the tortures, sheer physical tortures, which she may suffer.'

He walked up and down in desperation.

'And yet there's nothing whatever that one can do. One can't go to the police and say that a man has cast a magic spell on his wife.'
