eyes. "Yes, I think we had better do as you suggest."

We got off, paid our fare, and the trap rattled back on its way to Leatherhead.

"I thought it as well," said Holmes, as we climbed the stile, "that this fellow should think we had come here as architects, or on some definite business. It may stop his gossip. Good-afternoon, Miss Stoner. You see that we have been as good as our word."

Our client of the morning had hurried forward to meet us with a face which spoke her joy. "I have been waiting so eagerly for you," she cried, shaking hands with us warmly. "All has turned out splendidly. Dr. Roylott has gone to town, and it is unlikely that he will be back before evening."

"We have had the pleasure of making the doctor's acquaintance," said Holmes, and in a few words he sketched out what had occurred. Miss Stoner turned white to the lips as she listened.

"Good heavens!" she cried, "he has followed me, then."

"So it appears."

"He is so cunning that I never know when I am safe from him. What will he say when he returns?"

"He must guard himself, for he may find that there is some one more cunning than himself upon his track. You must lock yourself up from him to-night. If he is violent, we shall take you away to your aunt's at Harrow. Now, we must make the best use of our time, so kindly take us at once to the rooms which we are to examine."

The building was of gray, lichenblotched stone, with a high central portion, and two curving wings, like the claws of a crab, thrown out on each side. In one of these wings the windows were broken, and blocked with wooden boards, while the roof was partly caved in, a picture of ruin. The central portion was in little better repair, but the right-hand block was comparatively modern, and the blinds in the windows, with the blue smoke curling up from the chimneys, showed that this was where the family re

sided. Some scaffolding had been erected against the end wall, and the stone-work had been broken into, but there were no signs of any workmen at the moment of our visit. Holmes walked slowly up and down the ill-trimmed lawn, and examined with deep attention the outsides of the windows.

"This, I take it, belongs to the room in which you used to sleep, the centre one to your sister's, and the one next to the main building to Dr. Roylott's chamber?"

"Exactly so. But I am now sleeping in the middle one."

"Pending the alterations, as I understand. By-the-way, there does not seem to be any very pressing need for repairs at that end wall.

"Ah! that is suggestive. Now, on the other side of this narrow wing runs the corridor from which these three rooms open. There are windows in it, of course?"

"Yes, but very small ones. Too narrow for any one to pass through."

"As you both locked your doors at night, your rooms were unapproachable from that side. Now, would you have the kindness to go into your room and bar your shutters."

cess.

Miss Stoner did so, and Holmes, after a careful examination through the open window, endeavored in every way to force the shutter open, but without sucThere was no slit through which a knife could be passed to raise the bar. Then with his lens he tested the hinges, but they were of solid iron, built firmly into the massive masonry. "Hum!" said he, scratching his chin in some perplexity; "my theory certainly presents some difficulties. No one could pass these shutters if they were bolted. Well, we shall see if the inside throws any light upon the matter."

A small side door led into the whitewashed corridor from which the three bedrooms opened. bedrooms opened. Holmes refused to examine the third chamber, so we passed

at once to the second, that in which Miss Stoner was now sleeping, and in which her sister had met with her fate. It was a homely little room, with a low ceiling and a gaping fireplace, after the fashion of old country-houses. A brown chest of drawers stood in one corner, a narrow white-counterpaned bed in another, and a dressing-table on the left-hand side of the window. These articles, with two small wicker-work chairs, made up all the furniture in the room, save for a square of Wilton carpet in the center. The The boards round and the panelling of the walls were of brown, worm-eaten oak, so old and discolored that it may have dated from the original building of the house. Holmes drew one of the chairs into a corner and sat silent, while his eyes travelled round and round and up and down, taking in every detail of the apartment.

"Where does that bell communicate with?" he asked, at last, pointing to a thick bell-rope which hung down beside the bed, the tassel actually lying upon the pillow.

"It goes to the house-keeper's room." "It looks newer than the other things?" "Yes, it was only put there a couple of years ago."

"Your sister asked for it, I suppose?" "No, I never heard of her using it. We used always to get what we wanted for ourselves."

"Indeed, it seemed unnecessary to put so nice a bell-pull there. You will excuse me for a few minutes while I satisfy myself as to this floor." He threw himself down upon his face with his lens in his hand, and crawled swiftly backward and forward, examining minutely the cracks between the boards. Then he did the same with the wood-work with which the chamber was panelled. Finally he walked over to the bed, and spent some time in staring at it, and in running his eye up and down the wall. Finally he took the bell-rope in his hand and gave it a brisk tug.

"Why, it's a dummy," said he. "Won't it ring?"

"No, it is not even attached to a wire.

This is very interesting. You can see now that it is fastened to a hook just above where the little opening for the ventilator is."

"How very absurd! I never noticed that before."

"Very strange!" muttered Holmes, pulling at the rope. "There are one or two very singular points about this room. For example, what a fool a builder must be to open a ventilator into another room, when, with the same trouble, he might have communicated with the outside air!" "That is also quite modern," said the lady.

'Done about the same time as the bellrope?" remarked Holmes.

"Yes, there were several little changes carried out about that time."

"They seem to have been of a most interesting character-dummy bell-ropes, and ventilators which do not ventilate. With your permission, Miss Stoner, we shall now carry our researches into the inner apartment."

Dr. Grimesby Roylott's chamber was larger than that of his step-daughter, but was as plainly furnished. A camp-bed, a small wooden shelf full of books, mostly of a technical character, an arm-chair beside the bed, a plain wooden chair against the wall, a round table, and a large iron safe were the principal things which met the eye. Holmes walked slowly round and examined each and all of them with the keenest interest.

"What's in here?" he asked, tapping the safe.

"My step-father's business papers." "Oh! you have seen inside, then?" "Only once, some years ago. I remember that it was full of papers." "There isn't a cat in it, for example?" "No. What a strange idea!" "Well, look at this!" He took up a small saucer of milk which stood on the top of it.

"No, we don't keep a cat. But there is a cheetah and a baboon."

"Ah, yes, of course! Well, a cheetah is just a big cat, and yet a saucer of milk does not go very far in satisfying its

wants, I dare say. There is one point which I should wish to determine." He squatted down in front of the wooden chair, and examined the seat of it with the greatest attention.

"Thank you. That is quite settled," said he, rising and putting his lens in his pocket. "Hello! Here is something interesting!"

The object which had caught his eye was a small dog lash hung on one corner of the bed. The lash, however, was curled upon itself, and tied so as to make a loop of whip-cord.

"What do you make of that, Watson?" "It's a common enough lash. But I don't know why it should be tied."

"That is not quite so common, is it? Ah, me! it's a wicked world, and when a clever man turns his brains to crime it is the worst of all. I think that I have seen enough now, Miss Stoner, and with your permission we shall walk out upon the lawn."

I had never seen my friend's face so grim or his brow so dark as it was when we turned from the scene of this investigation. We had walked several times up and down the lawn, neither Miss Stoner nor myself liking to break in upon his thoughts before he roused himself from his reverie.

"It is very essential, Miss Stoner,” said he, "that you should absolutely follow my advice in every respect."

"I shall most certainly do so." "The matter is too serious for any hesitation. Your life may depend upon your compliance."

"I assure you that I am in your hands." "In the first place, both my friend and I must spend the night in your room." Both Miss Stoner and I gazed at him in astonishment.

"Yes, it must be so. Let me explain. I believe that that is the village inn over there?"

"Yes, that is the 'Crown.'

"Then for pity's sake tell me what was the cause of my sister's death."

"I should prefer to have clearer proofs before I speak."

"You can at least tell me whether my own thought is correct, and if she died from some sudden fright."

"No, I do not think so. I think that there was probably some more tangible cause. And now, Miss Stoner, we must leave you, for if Dr. Roylott returned and saw us, our journey would be in vain. Good-bye, and be brave, for if you will do what I have told you, you may rest assured that we shall soon drive away the dangers that threaten you."

Sherlock Holmes and I had no difficulty in engaging a bed-room and sittingroom at the "Crown Inn." They were on the upper floor, and from our window we could command a view of the avenue gate, and of the inhabited wing of Stoke Moran Manor House. At dusk we saw Dr. Grimesby Roylott drive past, his huge form looming up beside the little figure of the lad who drove him. The

the heavy iron gates, and we heard the hoarse roar of the doctor's voice, and saw the fury with which he shook his clinched

fists at him. The trap drove on, and a few minutes later we saw a sudden light spring up among the trees as the lamp was lit in one of the sitting-rooms.

"Do you know, Watson," said Holmes, as we sat together in the gathering darkness, "I have really some scruples as to taking you to-night. There is a distinct element of danger.'

"Can I be of assistance?"

"Your presence might be invaluable." "Then I shall certainly come." "It is very kind of you."

"You speak of danger. You have evidently seen more in these rooms than was visible to me."

"No, but I fancy that I may have deduced a little more. I imagine that you saw all that I did."

"I saw nothing remarkable save the bell-rope, and what purpose that could answer I confess is more than I can imagine."

"You saw the ventilator, too?"

"Yes, but I do not think that it is such a very unusual thing to have a small opening between two rooms. It was so small that a rat could hardly pass through."

"I knew that we should find a ventilator before ever we came to Stoke Moran." "My dear Holmes!"

"Oh yes, I did. You remember in her statement she said that her sister could smell Dr. Roylott's cigar. Now, of course that suggested at once that there must be a communication between the two rooms. It could only be a small one, or it would have been remarked upon at the coroner's inquiry. I deduced a ventilator."

"But what harm can there be in that?" "Well, there is at least a curious coincidence of dates. A ventilator is made, a cord is hung, and a lady who sleeps in the bed dies. Does not that strike you?"

"I cannot as yet see any connection." "Did you observe anything very peculiar about that bed?

"No."

"It was clamped to the floor. Did you ever see a bed fastened like that before?"

"I cannot say that I have."

"The lady could not move her bed. It must always be in the same relative position to the ventilator and to the ropefor so we may call it, since it was clearly never meant for a bell-pull."

"Holmes," I cried, "I seem to see dimly what you are hinting at. We are only just in time to prevent some subtle and horrible crime."

"Subtle enough and horrible enough. When a doctor does go wrong, he is the first of criminals. He has nerve and he has knowledge. Palmer and Pritchard were among the heads of their profession. This man strikes even deeper, but I think, Watson, that we shall be able to strike deeper still. But we shall have horrors enough before the night is over; for goodness' sake let us have a quiet pipe, and turn our minds for a few hours to something more cheerful."

About nine o'clock the light among the trees was extinguished, and all was dark in the direction of the Manor House. Two hours passed slowly away, and then. suddenly, just at the stroke of eleven, a single bright light shone out right in front of us.

"That is our signal," said Holmes, springing to his feet; "it comes from the middle window."

As we passed out he exchanged a few words with the landlord, explaining that we were going on a late visit to an acquaintance, and that it was possible that we might spend the night there. A moment later we were out on the dark road, a chill wind blowing in our faces, and one yellow light twinkling in front of us through the gloom to guide us on our sombre errand.

There was little difficulty in entering the grounds, for unrepaired breaches gaped in the old park wall. Making our way among the trees, we reached the lawn, crossed it, and were about to enter through the window, when out from a clump of laurel bushes there darted what seemed to be a hideous and distorted child. who threw itself upon the grass with

writhing limbs, and then ran swiftly across the lawn into the darkness. "My God!" I whispered; "did you see it ?"

Holmes was for the moment as startled as I. His hand closed like a vise upon my wrist in his agitation. Then he broke into a low laugh, and put his lips to my

ear.

"It is a nice household," he murmured. "That is the baboon."

I had forgotten the strange pets which the doctor affected. There was a cheetah, too; perhaps we might find it upon our shoulders at any moment. I confess that I felt easier in my mind when, after following Holmes's example and slipping off my shoes, I found myself inside the bedroom. My companion noiselessly closed the shutters, moved the lamp onto the table, and cast his eyes round the room. All was as we had seen it in the daytime. Then creeping up to me and making a trumpet of his hand, he whispered into my ear again so gently that it was all that I could do to distinguish the words: "The least sound would be fatal to our plans."

I nodded to show that I had heard. "We must sit without light. He would see it through the ventilator."

I nodded again.

"Do not go asleep; your very life may depend upon it. Have your pistol ready in case we should need it. I will sit on the side of the bed, and you in that chair."

I took out my revolver and laid it on the corner of the table.

Holmes had brought up a long thin cane, and this he placed upon the bed beside him. By it he laid the box of matches and the stump of a candle. Then he turned down the lamp, and we were left in darkness.

How shall I ever forget that dreadful vigil? I could not hear a sound, not even the drawing of a breath, and yet I know that my companion sat open-eyed, within a few feet of me, in the same state of nervous tension in which I was myself. The shutters cut off the least ray of light,

and we waited in absolute darkness. From outside came the occasional cry of a night-bird, and once at our very window a long-drawn cat-like whine, which told us that the cheetah was indeed at liberty. Far away we could hear the deep tones of the parish clock, which boomed out every quarter of an hour. How long they seemed, those quarters! Twelve struck, and one and two and three, and still we sat waiting silently for whatever might befall.

Suddenly there was the momentary gleam of a light up in the direction of the ventilator, which vanished immediately, but was succeeded by a strong smell of burning oil and heated metal. Some one in the next room had lit a darklantern. I heard a gentle sound of movement, and then all was silent once more, though the smell grew stronger. half an hour I sat with straining ears. Then suddenly another sound became audible a very gentle, soothing sound, like that of a small jet of steam escaping continually from a kettle. The instant that we heard it, Holmes sprang from the bed, struck a match, and lashed furiously with his cane at the bell-pull.

For

"You see it, Watson?" he yelled. "You see it?"

But I saw nothing. At the moment when Holmes struck the light I heard a low, clear whistle, but the sudden glare flashing into my weary eyes made it impossible for me to tell what it was at which my friend lashed so savagely. I could, however, see that his face was deadly pale, and filled with horror and loathing.

He had ceased to strike, and was gazing up at the ventilator, when suddenly there broke from the silence of the night the most horrible cry to which I have ever listened. It swelled up louder and louder, a hoarse yell of pain and fear and anger all mingled in the one dreadful shriek. They say that away down in the village, and even in the distant parsonage, that cry raised the sleepers from their beds. It struck cold to our hearts, and I stood gazing at Holmes, and he at me,
