“I don’t quite know how to make her clear to you, Watson. Perhaps you may meet her before we are through, and you can use your own gift of words. She is beautiful, but with the ethereal other-world beauty of some fanatic whose thoughts are set on high. I have seen such faces in the pictures of the old masters of the Middle Ages. How a beastman could have laid his vile paws upon such a being of the beyond I cannot imagine. You may have noticed how extremes call to each other, the spiritual to the animal, the cave-man to the angel. You never saw a worse case than this.

“She knew what we had come for, of course — that villain had lost no time in poisoning her mind against us. Miss Winter’s advent rather amazed her, I think, but she waved us into our respective chairs like a reverend abbess receiving two rather leprous mendicants. If your head is inclined to swell, my dear Watson, take a course of Miss Violet de Merville.

“ ‘Well, sir,’ said she in a voice like the wind from an iceberg, ‘your name is familiar to me. You have called, as I understand, to malign my fiance, Baron Gruner. It is only by my father’s request that I see you at all, and I warn you in advance that anything you can say could not possibly have have the slightest effect upon my mind.’

“I was sorry for her, Watson. I thought of her for the moment as I would have thought of a daughter of my own. I am not often eloquent. I use my head, not my heart. But I really did plead with her with all the warmth of words that I could find in my nature. I pictured to her the awful position of the woman who only wakes to a man’s character after she is his wife — a woman who has to submit to be caressed by bloody hands and lecherous lips. I spared her nothing — the shame, the fear, the agony, the hopelessness of it all. All my hot words could not bring one tinge of colour to those ivory cheeks or one gleam of emotion to those abstracted eyes. I thought of what the rascal had said about a post-hypnotic influence. One could really believe that she was living above the earth in some ecstatic dream. Yet there was nothing indefinite in her replies.

“ ‘I have listened to you with patience, Mr. Holmes,’ said she. ‘The effect upon my mind is exactly as predicted. I am aware that Adelbert, that my fiance, has had a stormy life in which he has incurred bitter hatreds and most unjust aspersions. You are only the last of a series who have brought their slanders before me. Possibly you mean well, though I learn that you are a paid agent who would have been equally willing to act for the Baron as against him. But in any case I wish you to understand once for all that I love him and that he loves me, and that the opinion of all the world is no more to me than the twitter of those birds outside the window. If his noble nature has ever for an instant fallen, it may be that I have been specially sent to raise it to its true and lofty level. I am not clear’ — here she turned eyes upon my companion — ‘who this young lady may be.’

"The house in the Square Lamartine is occupied by Prasville's men."

"Don't worry, Sebastiani. I shall get in. If they don't open the door, there's always the window. And, if the window won't open, I shall arrange with one of Prasville's men. It's a question of money, that's all. And, thank goodness, I shan't be short of that, henceforth! Good-night, Daubrecq."

He went out, accompanied by Sebastiani, and the heavy door closed after them.

Lupin at once effected his retreat, in accordance with a plan which he had worked out during this scene.

The plan was sunple enough: to scramble, by means of his rope, to the bottom of the cliff, take his friends with him, jump into the motor-car and attack d'Albufex and Sebastiani on the deserted road that leads to Aumale Station. There could be no doubt about the issue of the contest. With d'Albufex and Sebastiani prisoners; it would be an easy matter to make one of them speak. D'Albufex had shown him how to set about it; and Clarisse Mergy would be inflexible where it was a question of saving her son.

He took the rope with which he had provided himself and groped about to find a jagged piece of rock round which to pass it, so as to leave two equal lengths hanging, by which he could let himself down. But, when he found what he wanted, instead of acting swiftly - for the business was urgent - he stood motionless, thinking. His scheme failed to satisfy him at the last moment.

"It's absurd, what I'm proposing," he said to himself. "Absurd and illogical. How can I tell that d'Albufex and Sebastiani will not escape me? How can I even tell that, once they are in my power, they will speak? No, I shall stay. There are better things to try... much better things. It's not those two I must be at, but Daubrecq. He's done for; he has not a kick left in him. If he has told the marquis his secret, there is no reason why he shouldn't tell it to Clarisse and me, when we employ the same methods. That's settled! We'll kidnap the Daubrecq bird." And he continued, "Besides, what do I risk? If the scheme miscarries, Clarisse and I will rush off to Paris and, together with Prasville, organize a careful watch in the Square Lamartine to prevent d'Albufex from benefiting by Daubrecq's revelations. The great thing is for Prasville to be warned of the danger. He shall be."

The church-clock in a neighbouring village struck twelve. That gave Lupin six or seven hours to put his new plan into execution. He set to work forthwith.

When moving away from the embrasure which had the window at the bottom of it, he had come upon a clump of small shrubs in one of the hollows of the cliff. He cut away a dozen of these, with his knife, and whittled them all down to the same size. Then he cut off two equal lengths from his rope. These were the uprights of the ladder. He fastened the twelve little sticks between the uprights and thus contrived a rope-ladder about six yards long.

When he returned to this post, there was only one of the three sons beside Daubrecq's bed in the torture-chamber. He was smoking his pipe by the lamp. Daubrecq was asleep.
