A small side door led into the whitewashed corridor from which the three 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 centre. 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 belt-rope which hung down beside the bed, the tassel actually lying upon the pillow.

“It goes to the housekeeper’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 bell-rope?” 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 armchair 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 stepfather’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 daresay. 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 whipcord.

“What do you make of that, Watson?”

“It’s a common enough lash. But I don’t know why if 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.”

“Very good. Your windows would be visible from there?”

“Certainly.”

“You must confine yourself to your room, on pretence of a headache, when your stepfather comes back. Then when you hear him retire for the night, you must open the shutters of your window, undo the hasp, put your lamp there as a signal to us, and then withdraw quietly with everything which you are likely to want into the room which you used to occupy. I have no doubt that, in spite of the repairs, you could manage there for one night.”

“Oh, yes, easily.”

“The rest you will leave in our hands.”

“But what will you do?”

“We shall spend the night in your room, and we shall investigate the cause of this noise which has disturbed you.”

“I believe, Mr. Holmes, that you have already made up your mind,” said Miss Stoner, laying her hand upon my companion’s sleeve.

“Perhaps I have.”

“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 bedroom and sitting-room 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 boy had some slight difficulty in undoing 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.”
