"What alternative could be conceived?" said I.

"You may well say so. And yet there were one or two points which worried young Edmunds, of the Berkshire Constabulary. A smart lad that! He was sent later to Allahabad. That was how I came into the matter, for he dropped in and smoked a pipe or two over it."

"A thin, yellow-haired man?"

"Exactly. I was sure you would pick up the trail presently."

"But what worried him?"

"Well, we were both worried. It was so deucedly difficult to reconstruct the affair. Look at it from the lion's point of view. He is liberated. What does he do? He takes half a dozen bounds forward, which brings him to Ronder. Ronder turns to fly – the claw-marks were on the back of his head – but the lion strikes him down. Then, instead of bounding on and escaping, he returns to the woman, who was close to the cage, and he knocks her over and chews her face up. Then, again, those cries of hers would seem to imply that her husband had in some way failed her. What could the poor devil have done to help her? You see the difficulty?"

"Quite."

"And then there was another thing. It comes back to me now as I think it over. There was some evidence that just at the time the lion roared and the woman screamed, a man began shouting in terror."

"This man Ronder, no doubt."

"Well, if his skull was smashed in you would hardly expect to hear from him again. There were at least two witnesses who spoke of the cries of a man being mingled with those of a woman."

"I should think the whole camp was crying out by then. As to the other points, I think I could suggest a solution."

"I should be glad to consider it."

"The two were together, ten yards from the cage, when the lion got loose. The man turned and was struck down. The woman conceived the idea of getting into the cage and shutting the door. It was her only refuge. She made for it, and just as she reached it the beast bounded after her and knocked her over. She was angry with her husband for having encouraged the beast's rage by turning. If they had faced it they might have cowed it. Hence her cries of 'Coward!' "

"Brilliant, Watson! Only one flaw in your diamond."

"What is the flaw, Holmes?"

"If they were both ten paces from the cage, how came the beast to get loose?"

"Is it possible that they had some enemy who loosed it?"

"And why should it attack them savagely when it was in the habit of playing with them, and doing tricks with them inside the cage?"

"Possibly the same enemy had done something to enrage it."

Holmes looked thoughtful and remained in silence for some moments.

"Well, Watson, there is this to be said for your theory. Ronder was a man of many enemies. Edmunds told me that in his cups he was horrible. A huge bully of a man, he cursed and slashed at everyone who came in his way. I expect those cries about a monster, of which our visitor has spoken, were nocturnal reminiscences of the dear departed. However, our speculations are futile until we have all the facts. There is a cold partridge on the sideboard, Watson, and a bottle of Montrachet. Let us renew our energies before we make a fresh call upon them."

When our hansom deposited us at the house of Mrs. Merrilow, we found that plump lady blocking up the open door of her humble but retired abode. It was very clear that her chief preoccupation was lest she should lose a valuable lodger, and she implored us, before showing us up, to say and do nothing which could lead to so undesirable an end. Then, having reassured her, we followed her up the straight, badly carpeted staircase and were shown into the room of the mysterious lodger.

It was a close, musty, ill-ventilated place, as might be expected, since its inmate seldom left it. From keeping beasts in a cage, the woman seemed, by some retribution of fate, to have become herself a beast in a cage. She sat now in a broken armchair in the shadowy corner of the room. Long years of inaction had coarsened the lines of her figure, but at some period it must have been beautiful, and was still full and voluptuous. A thick dark veil covered her face, but it was cut off close at her upper lip and disclosed a perfectly shaped mouth and a delicately rounded chin. I could well conceive that she had indeed been a very remarkable woman. Her voice, too, was well modulated and pleasing.

"My name is not unfamiliar to you, Mr. Holmes," said she. "I thought that it would bring you."

"That is so, madam, though I do not know how you are aware that I was interested in your case."

"l learned it when I had recovered my health and was examined by Mr. Edmunds, the county detective. I fear I lied to him. Perhaps it would have been wiser had I told the truth."

"It is usually wiser to tell the truth. But why did you lie to him?"

"Because the fate of someone else depended upon it. I know that he was a very worthless being, and yet I would not have his destruction upon my conscience. We had been so close – so close!"

"But has this impediment been removed?"

"Yes, sir. The person that I allude to is dead."

"Then why should you not now tell the police anything you know?"

"Because there is another person to be considered. That other person is myself. I could not stand the scandal and publicity which would come from a police examination. I have not long to live, but I wish to die undisturbed. And yet I wanted to find one man of judgment to whom I could tell my terrible story, so that when I am gone all might be understood."

"You compliment me, madam. At the same time, I am a responsible person. I do not promise you that when you have spoken I may not myself think it my duty to refer the case to the police."

"I think not, Mr. Holmes. I know your character and methods too well, for I have followed your work for some years. Reading is the only pleasure which fate has left me, and I miss little which passes in the world. But in any case, I will take my chance of the use which you may make of my tragedy. It will ease my mind to tell it."

"My friend and I would be glad to hear it."

The woman rose and took from a drawer the photograph of a man. He was clearly a professional acrobat, a man of magnificent physique, taken with his huge arms folded across his swollen chest and a smile breaking from under his heavy mustache – the self-satisfied smile of the man of many conquests.

"That is Leonardo," she said.

"Leonardo, the strong man, who gave evidence?"

"The same. And this – this is my husband."

It was a dreadful face – a human pig, or rather a human wild boar, for it was formidable in its bestiality. One could imagine that vile mouth champing and foaming in its rage, and one could conceive those small, vicious eyes darting pure malignancy as they looked forth upon the world. Ruffian, bully, beast – it was all written on that heavy-jowled face.

"Those two pictures will help you, gentlemen, to understand the story. I was a poor circus girl brought up on the sawdust, and doing springs through the hoop before I was ten. When I became a woman this man loved me, if such lust as his can be called love, and in an evil moment I became his wife. From that day I was in hell, and he the devil who tormented me. There was no one in the show who did not know of his treatment. He deserted me for others. He tied me down and lashed me with his riding whip when I complained. They all pitied me and they all loathed him, but what could they do? They feared him, one and all. For he was terrible at all times, and murderous when he was drunk. Again and again he was had up for assault, and for cruelty to the beasts, but he had plenty of money and the fines were nothing to him. The best men all left us, and the show began to go downhill. It was only Leonardo and I who kept it up – with little Jimmy Griggs, the clown. Poor devil, he had not much to be funny about, but he did what he could to hold things together.
