‘ . . . You have some influence over Agnes. Try what you can do, Henry, to make her take a sensible view of the matter. There is really nothing to make a fuss about. My wife’s maid knocked at her door early in the morning, with the customary cup of tea. Getting no answer, she went round to the dressing-room — found the door on that side unlocked — and discovered Agnes on the bed in a fainting fit. With my wife’s help, they brought her to herself again; and she told the extraordinary story which I have just repeated to you. You must have seen for yourself that she has been over-fatigued, poor thing, by our long railway journeys: her nerves are out of order — and she is just the person to be easily terrified by a dream. She obstinately refuses, however, to accept this rational view. Don’t suppose that I have been severe with her! All that a man can do to humour her I have done. I have written to the Countess (in her assumed name) offering to restore the room to her. She writes back, positively declining to return to it. I have accordingly arranged (so as not to have the thing known in the hotel) to occupy the room for one or two nights, and to leave Agnes to recover her spirits under my wife’s care. Is there anything more that I can do? Whatever questions Agnes has asked of me I have answered to the best of my ability; she knows all that you told me about Francis and the Countess last night. But try as I may I can’t quiet her mind. I have given up the attempt in despair, and left her in the drawing-room. Go, like a good fellow, and try what you can do to compose her.’

In those words, Lord Montbarry stated the case to his brother from the rational point of view. Henry made no remark, he went straight to the drawing-room.

He found Agnes walking rapidly backwards and forwards, flushed and excited. ‘If you come here to say what your brother has been saying to me,’ she broke out, before he could speak, ‘spare yourself the trouble. I don’t want common sense — I want a true friend who will believe in me.’

‘I am that friend, Agnes,’ Henry answered quietly, ‘and you know it.’

‘You really believe that I am not deluded by a dream?’

I know that you are not deluded — in one particular, at least.’

‘In what particular?’

‘In what you have said of the Countess. It is perfectly true —’

Agnes stopped him there. ‘Why do I only hear this morning that the Countess and Mrs. James are one and the same person?’ she asked distrustfully. ‘Why was I not told of it last night?’

‘You forget that you had accepted the exchange of rooms before I reached Venice,’ Henry replied. ‘I felt strongly tempted to tell you, even then — but your sleeping arrangements for the night were all made; I should only have inconvenienced and alarmed you. I waited till the morning, after hearing from my brother that you had yourself seen to your security from any intrusion. How that intrusion was accomplished it is impossible to say. I can only declare that the Countess’s presence by your bedside last night was no dream of yours. On her own authority I can testify that it was a reality.’

‘On her own authority?’ Agnes repeated eagerly. ‘Have you seen her this morning?’

‘I have seen her not ten minutes since.’

‘What was she doing?’

She was busily engaged in writing. I could not even get her to look at me until I thought of mentioning your name.’

‘She remembered me, of course?’

‘She remembered you with some difficulty. Finding that she wouldn’t answer me on any other terms, I questioned her as if I had come direct from you. Then she spoke. She not only admitted that she had the same superstitious motive for placing you in that room which she had acknowledged to Francis — she even owned that she had been by your bedside, watching through the night, “to see what you saw,” as she expressed it. Hearing this, I tried to persuade her to tell me how she got into the room. Unluckily, her manuscript on the table caught her eye; she returned to her writing. “The Baron wants money,” she said; “I must get on with my play.” What she saw or dreamed while she was in your room last night, it is at present impossible to discover. But judging by my brother’s account of her, as well as by what I remember of her myself, some recent influence has been at work which has produced a marked change in this wretched woman for the worse. Her mind (since last night, perhaps) is partially deranged. One proof of it is that she spoke to me of the Baron as if he were still a living man. When Francis saw her, she declared that the Baron was dead, which is the truth. The United States Consul at Milan showed us the announcement of the death in an American newspaper. So far as I can see, such sense as she still possesses seems to be entirely absorbed in one absurd idea — the idea of writing a play for Francis to bring out at his theatre. He admits that he encouraged her to hope she might get money in this way. I think he did wrong. Don’t you agree with me?’

Without heeding the question, Agnes rose abruptly from her chair.

‘Do me one more kindness, Henry,’ she said. ‘Take me to the Countess at once.’

Henry hesitated. ‘Are you composed enough to see her, after the shock that you have suffered?’ he asked.

She trembled, the flush on her face died away, and left it deadly pale. But she held to her resolution. ‘You have heard of what I saw last night?’ she said faintly.

‘Don’t speak of it!’ Henry interposed. ‘Don’t uselessly agitate yourself.’

‘I must speak! My mind is full of horrid questions about it. I know I can’t identify it — and yet I ask myself over and over again, in whose likeness did it appear? Was it in the likeness of Ferrari? or was it —?’ she stopped, shuddering. ‘The Countess knows, I must see the Countess!’ she resumed vehemently. ‘Whether my courage fails me or not, I must make the attempt. Take me to her before I have time to feel afraid of it!’

Henry looked at her anxiously. ‘If you are really sure of your own resolution,’ he said, ‘I agree with you — the sooner you see her the better. You remember how strangely she talked of your influence over her, when she forced her way into your room in London?’

‘I remember it perfectly. Why do you ask?’

‘For this reason. In the present state of her mind, I doubt if she will be much longer capable of realizing her wild idea of you as the avenging angel who is to bring her to a reckoning for her evil deeds. It may be well to try what your influence can do while she is still capable of feeling it.’

He waited to hear what Agnes would say. She took his arm and led him in silence to the door.

They ascended to the ............
