“And it will, too,” remarked Holmes. “Very good, Mrs. Merrilow. I should like to have a little chat with Dr. Watson. That will carry us till lunch-time. About three o’clock you may expect to see us at your house in Brixton.”

Our visitor had no sooner waddled out of the room — no other verb can describe Mrs. Merrilow’s method of progression — than Sherlock Holmes threw himself with fierce energy upon the pile of commonplace books in the corner. For a few minutes there was a constant swish of the leaves, and then with a grunt of satisfaction he came upon what he sought. So excited was he that he did not rise, but sat upon the floor like some strange Buddha, with crossed legs, the huge books all round him, and one open upon his knees.

“The case worried me at the time, Watson. Here are my marginal notes to prove it. I confess that I could make nothing of it. And yet I was convinced that the coroner was wrong. Have you no recollection of the Abbas Parva tragedy?”

“None, Holmes.”

“And yet you were with me then. But certainly my own impression was very superficial. For there was nothing to go by, and none of the parties had engaged my services. Perhaps you would care to read the papers?”

“Could you not give me the points?”

“That is very easily done. It will probably come back to your memory as I talk. Ronder, of course, was a household word. He was the rival of Wombwell, and of Sanger, one of the greatest showmen of his day. There is evidence, evidence however, that he took to drink, and that both he and his show were on the down grade at the time of the great tragedy. The caravan had halted for the night at Abbas Parva, which is a small village in Berkshire, when this horror occurred. They were on their way to Wimbledon, travelling by road, and they were simply camping and not exhibiting, as the place is so small a one that it would not have paid them to open.

“They had among their exhibits a very fine North African lion. Sahara King was its name, and it was the habit, both of Ronder and his wife, to give exhibitions inside its cage. Here, you see, is a photograph of the performance by which you will perceive that Ronder was a huge porcine person and that his wife was a very magnificent woman. It was deposed at the inquest that there had been some signs that the lion was dangerous, but, as usual, familiarity begat contempt, and no notice was taken of the fact.

“It was usual for either Ronder or his wife to feed the lion at night. Sometimes one went, sometimes both, but they never allowed anyone else to do it, for they believed that so long as they were the food-carriers he would regard them as benefactors and would never molest them. On this particular night, seven years ago, they both went, and a very terrible happening followed, the details of which have never been made clear.

“It seems that the whole camp was roused near midnight by the roars of the animal and the screams of the woman. The different grooms and employees rushed from their tents, carrying lanterns, and by their light an awful sight was revealed. Ronder lay, with the back of his head crushed in and deep claw-marks across his scalp, some ten yards from the cage, which was open. Close to the door of the cage lay Mrs. Ronder upon her back, with the creature squatting and snarling above her. It had torn her face in such a fashion that it was never thought that she could live. Several of the circus men, headed by Leonardo, the strong man, and Griggs, the clown, drove the creature off with poles, upon which it sprang back into the cage and was at once locked in. How it had got loose was a mystery. It was conjectured that the pair intended to enter the cage, but that when the door was loosed the creature bounded out upon them. There was no other point of interest in the evidence save that the woman in a delirium of agony kept screaming, ‘Coward! Coward!’ as she was carried back to the van in which they lived. It was six months before she was fit to give evidence, but the inquest was duly held, with the obvious verdict of death from misadventure.”

"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.
