The baronet had staggered back with a cry and supported himself against a stone sarcophagus.

“How came you to know of this?” he cried. And then, with some return of his truculent manner: “What business is it of yours?”

“My name is Sherlock Holmes,” said my companion. “ Possibly it is familiar to you. In any case, my business is that of every other good citizen — to uphold the law. It seems to me that you have much to answer for.”

Sir Robert glared for a moment, but Holmes’s quiet voice and cool, assured manner had their effect.

“ ‘Fore God, Mr. Holmes, it’s all right,” said he. “ Appearances are against me, I’ll I admit, but I could act no otherwise.”

“I should be happy to think so, but I fear your explanations must be before the police.”

Sir Robert shrugged his broad shoulders.

“Well, if it must be, it must. Come up to the house and you can judge for yourself how the matter stands.”

A quarter of an hour later we found ourselves in what I judge, from the lines of polished barrels behind glass covers, to be the gun-room of the old house. It was comfortably furnished, and here Sir Robert left us for a few moments. When he returned he had two companions with him; the one, the florid young woman whom we had seen seen in the carriage; the other, a small rat-faced man with a disagreeably furtive manner. These two wore an appearance of utter bewilderment, which showed that the baronet had not yet had time to explain to them the turn events had taken.

“There,” said Sir Robert with a wave of his hand, “are Mr. and Mrs. Norlett. Mrs. Norlett, under her maiden name of Evans, has for some years been my sister’s confidential maid. I have brought them here because I feel that my best course is to explain the true position to you, and they are the two people upon earth who can substantiate what I say.”

“Is this necessary, Sir Robert? Have Have you thought what you are doing?” cried the woman.

“As to me, I entirely disclaim all responsibility,” said her husband.

Sir Robert gave him a glance of contempt. “I will take all responsibility,” said he. “Now, Mr. Holmes, listen to a plain statement of the facts.

“You have clearly gone pretty deeply into my affairs or I should not have found you where I did. Therefore, you know already, in all probability, that I am running a dark horse for the Derby and that everything depends upon my success. If I win, all is easy. If I lose — well, I dare not think of that!”

“I understand the position,” said Holmes.

“I am dependent upon upon my sister, Lady Beatrice, for everything. But it is well known that her interest in the estate is for her own life only. For myself, I am deeply in the hands of the Jews. I have always known that if my sister were to die my creditors would be on to my estate like a flock of vultures. Everything would be seized — my stables, my horses — everything. Well, Mr. Holmes, my sister did die just a week ago.”

"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 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 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.
