The two boats fastened to the little pier that jutted out from the garden lay rocking in its shadow. Here and there lighted windows showed through the thick mist on the margins of the lake. The Enghien Casino opposite blazed with light, though it was late in the season, the end of September. A few stars appeared through the clouds. A light breeze ruffled the surface of the water.

Arsene Lupin left the summer-house where he was smoking a cigar and, bending forward at the end of the pier:

"Growler?" he asked. "Masher?... Are you there?"

A man rose from each of the boats, and one of them answered:

"Yes, governor."

"Get ready. I hear the car coming with Gilbert and Vaucheray."

He crossed the garden, walked round a house in process of construction, the scaffolding of which loomed overhead, and cautiously opened the door on the Avenue de Ceinture. He was not mistaken: a bright light flashed round the bend and a large, open motor-car drew up, whence sprang two men in great-coats, with the collars turned up, and caps.

It was Gilbert and Vaucheray: Gilbert, a young fellow of twenty or twenty-two, with an attractive cast of features and a supple and sinewy frame; Vaucheray, older, shorter, with grizzled hair and a pale, sickly face.

"Well," asked Lupin, "did you see him, the deputy?"

"Yes, governor," said Gilbert, "we saw him take the 7.40 tram for Paris, as we knew he would."

"Then we are free to act?"

"Absolutely. The Villa Marie-Therese is ours to do as we we please with."

The chauffeur had kept his seat. Lupin gave him his orders:

"Don't wait here. It might attract attention. Be back at half-past nine exactly, in time to load the car unless the whole business falls through."

Why should it fall through?" observed Gilbert.

The motor drove away; and Lupin, taking the road to the lake with his two companions, replied:

"Why? Because I didn't prepare the plan; and, when I don't do a thing myself, I am only half-confident."

"Nonsense, governor! I've been working with you for three years now... I'm beginning to know the ropes!"

"Yes, my lad, you're beginning," said Lupin, "and that's just why I'm afraid of blunders... Here, get in with me... And you, Vaucheray, take the other boat... That's it... And now push off, boys... and make as little noise as you can."

Growler and Masher, the two oarsmen, made straight for the opposite bank, a little to the left of the casino.

They met a boat containing a couple locked in each other's arms, floating at random, and another in which a number of people were singing at the top of their voices. And that was all.

Lupin shifted closer to his companion and said, under his breath:

"Tell me, Gilbert, did you think of this job, or was it Vaucheray's idea?"

"Upon my word, I couldn't tell you: we've both of us been discussing it for weeks."

"The thing is, I don't trust Vaucheray: he's a low ruflian when one gets to know him... I can't make out why I don't get rid of him... "

"Oh, governor!"

"Yes, yes, I mean what I say: he's a dangerous fellow, to say nothing of the fact that he has some rather serious peccadilloes on his conscience."

“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, 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.”
