“This is Mrs. Merrilow, of South Brixton,” said my friend with a wave of the hand. “Mrs. Merrilow does not object to tobacco, Watson, if you wish to indulge your filthy habits. Mrs. Merrilow has an interesting story to tell which may well lead to further developments in which your presence may be useful.”

“Anything I can do —”

“You will understand, Mrs. Merrilow, that if I come to Mrs. Ronder I should prefer to have a witness. You will make her understand that before we arrive.”

“Lord bless you, Mr. Holmes,” said our visitor, “she is that anxious to see you that you might bring the whole parish at your heels!”

“Then we shall come early in the afternoon. Let us see that we have our facts correct before we start. If we go over them it will help Dr. Watson to understand the situation. You say that Mrs. Ronder has been your lodger for seven years and that you have only once seen her face.”

“And I wish to God I had not!” said Mrs. Merrilow.

“It was, I understand, terribly mutilated.”

“Well, Mr. Holmes, you would hardly say it was a face at all. That’s how it looked. Our milkman got a glimpse of her once peeping out of the upper window, and he dropped his tin and the milk all over the front garden. That is the kind of face it is. When I saw her — I happened on her unawares — she covered up quick, and then she said, ‘Now, Mrs. Merrilow, Merrilow you know at last why it is that I never raise my veil.’ ”

“Do you know anything about her history?”

“Nothing at all.”

“Did she give references when she came?”

“No, sir, but she gave hard cash, and plenty of it. A quarter’s rent right down on the table in advance and no arguing about terms. In these times a poor woman like me can’t afford to turn down a chance like that.”

“Did she give any reason for choosing your house?”

“Mine stands well back from the road and is more private than most. Then, again, I only take the one, and I have no family of my own. I reckon she had tried others and found that mine suited her best. It’s privacy she is after, and she is ready to pay for it.”

“You say that she never showed her face from first to last save on the one accidental occasion. Well, it is a very remarkable story, most remarkable, and I don’t wonder that you want it examined.”

“I don’t, Mr. Holmes. I am quite satisfied so long as I get my rent. You could not have a quieter lodger, or one who gives less trouble.”

“Then what has brought matters to a head?”

“Her health, Mr. Holmes. She seems to be wasting away. And there’s something terrible on her mind. ‘Murder!’ she cries. ‘Murder!’ And once I heard her: ‘You cruel beast! You monster!’ she cried. It was in the night, and it fair rang through the house and sent the shivers through me. So I went to her in the morning. ‘Mrs. Ronder,’ I says, ‘if you have anything that is troubling your soul, there’s the clergy,’ I says, ‘and there‘s the police. Between them you should get some help.’ ‘For God’s sake, not the police!’ says she, ‘and the clergy can’t change what is past. And yet,’ she says, ‘it would ease my mind if someone knew the truth before I died.’ ‘Well,’ says I, ‘if you won’t have the regulars, there is this detective man what we read about’ — beggin’ your pardon, Mr. Holmes. And she, she fair jumped at it. ‘That’s the man,’ says she. ‘I wonder I never thought of it before. Bring him here, Mrs. Merrilow, and if he won’t come, tell him I am the wife of Ronder‘s wild beast show. Say that, and give him the name Abbas Parva. Here it is as she wrote it, Abbas Parva. ‘That will bring him if he’s the man I think he is.’ ”

"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.
