“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 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 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. 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, 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, 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.”

"Whom did she ask for?"

"M. Michel Beaumont," replied the servant.

"Queer. And why why has she called?"

"All she said was that it was about the Enghien business... So I thought that... "

"What! The Enghien business! Then she knows that I am mixed up in that business... She knows that, by applying here... "

"I could not get anything out of her, but I thought, all the same, that I had better let her in."

"Quite right. Where is she?"

"In the drawing-room. I've put on the lights."

Lupin walked briskly across the hall and opened the door of the drawing-room:

"What are you talking about?" he said, to his man. "There's no one here."

"No one here?" said Achille, running up.

And the room, in fact, was empty.

"Well, on my word, this takes the cake!" cried the servant. "It wasn't twenty minutes ago that I came and had a look, to make sure. She was sitting over there. And there's nothing wrong with my eyesight, you know."

"Look here, look here," said Lupin, irritably. "Where were you while the woman was waiting?"

"In the hail, governor! I never left the hail for a second! I should have seen her go out, blow it!"

"Still, she's not here now... "

"So I see," moaned the man, quite flabbergasted.

"She must have got tired of waiting and gone away. But, dash it all, I should like to know how she got out!"

"How she got out?" said Lupin. "It doesn't take a wizard to tell that."

"What do you mean?"

"She got out through the window. Look, it's still ajar We are on the ground-floor... The street is almost always deserted, in the evenings. There's no doubt about it."

He had looked around him and satisfied himself that nothing had been taken away or moved. The room, for that matter, contained no knicknack of any value, no important paper that might have explained the woman's visit, followed by her sudden disappearance. And yet why that inexplicable flight?

"Has any one telephoned?" he asked.

"No."

"Any letters?"

"Yes, one letter by the last post."

"Where is it?"

"I put it on your mantel-piece, governor, as usual."

Lupin's bedroom was next to the drawing-room, but Lupin had permanently bolted the door between the two. He, therefore, had to go through the hall again.

Lupin switched on the electric light and, the next moment, said:

"I don't see it... "

"Yes... I put it next to the flower-bowl."

"There's nothing here at all."

"You must be looking in the wrong place, governor."

But Achille moved the bowl, lifted the clock, bent down to the grate, in vain: the letter was not there.

"Oh blast it, blast it!" he muttered. "She's done it... she's taken it... And then, when she had the letter, she cleared out... Oh, the slut!... "

Lupin said:

"You're mad! There's no way through between the two rooms."

"Then who did take it, governor?"

They were both of them silent. Lupin strove to control his anger and collect his ideas. He asked:

"Did you look at the envelope?"

"Yes."

"Anything particular about it?"

""Yes, it looked as if it had been written in a hurry, or scribbled, rather."
