"My dear fellow," said he, "Holmes, with all his wisdom, did not foresee some things which have happened since I have been on the moor. You understand me? I am sure that you are the last man in the world who would wish to be a spoil-sport. I must go out alone."

It put me in a most awkward position. I was at a loss what to say or what to do, and before I had made up my mind he picked up his cane and was gone.

But when I came to think the matter over my conscience reproached me bitterly for having on any pretext allowed him to go out of my sight.

I imagined what my feelings would be if I had to return to you and to confess that some misfortune had occurred through my disregard for your instructions. I a.s.sure you my cheeks flushed at the very thought. It might not even now be too late to overtake him, so I set off at once in the direction of Merripit House.

I hurried along the road at the top of my speed without seeing anything of Sir Henry, until I came to the point where the moor path branches off. There, fearing that perhaps I had come in the wrong direction after all, I mounted a hill from which I could command a view--the same hill which is cut into the dark quarry. Thence I saw him at once. He was on the moor path about a quarter of a mile off, and a lady was by his side who could only be Miss Stapleton. It was clear that there was already an understanding between them and that they had met by appointment. They were walking slowly along in deep conversation, and I saw her making quick little movements of her hands as if she were very earnest in what she was saying, while he listened intently, and once or twice shook his head in strong dissent. I stood among the rocks watching them, very much puzzled as to what I should do next. To follow them and break into their intimate conversation seemed to be an outrage, and yet my clear duty was never for an instant to let him out of my sight. To act the spy upon a friend was a hateful task. Still, I could see no better course than to observe him from the hill, and to clear my conscience by confessing to him afterwards what I had done. It is true that if any sudden danger had threatened him I was too far away to be of use, and yet I am sure that you will agree with me that the position was very difficult, and that there was nothing more which I could do.

Our friend, Sir Henry, and the lady had halted on the path and were standing deeply absorbed in their conversation, when I was suddenly aware that I was not the only witness of their interview. A wisp of green floating in the air caught my eye, and another glance showed me that it was carried on a stick by a man who was moving among the broken ground. It was Stapleton with his b.u.t.terfly-net. He was very much closer to the pair than I was, and he appeared to be moving in their direction.

At this instant Sir Henry suddenly drew Miss Stapleton to his side. His arm was round her, but it seemed to me that she was straining away from him with her face averted. He stooped his head to hers, and she raised one hand as if in protest. Next moment I saw them spring apart and turn hurriedly round. Stapleton was the cause of the interruption. He was running wildly towards them, his absurd net dangling behind him. He gesticulated and almost danced with excitement in front of the lovers.

What the scene meant I could not imagine, but it seemed to me that Stapleton was abusing Sir Henry, who offered explanations, which became more angry as the other refused to accept them. The lady stood by in haughty silence. Finally Stapleton turned upon his heel and beckoned in a peremptory way to his sister, who, after an irresolute glance at Sir Henry, walked off by the side of her brother. The naturalist's angry gestures showed that the lady was included in his displeasure. The baronet stood for a minute looking after them, and then he walked slowly back the way that he had come, his head hanging, the very picture of dejection.

What all this meant I could not imagine, but I was deeply ashamed to have witnessed so intimate a scene without my friend's knowledge. I ran down the hill therefore and met the baronet at the bottom. His face was flushed with anger and his brows were wrinkled, like one who is at his wit's ends what to do.

"Halloa, Watson! Where have you dropped from?" said he. "You don't mean to say that you came after me in spite of all?"

I explained everything to him: how I had found it impossible to remain behind, how I had followed him, and how I had witnessed all that had occurred. For an instant his eyes blazed at me, but my frankness disarmed his anger, and he broke at last into a rather rueful laugh.

"You would have thought the middle of that prairie a fairly safe place for a man to be private," said he, "but, by thunder, the whole countryside seems to have been out to see me do my wooing--and a mighty poor wooing at that! Where had you engaged a seat?"

"I was on that hill."

"Quite in the back row, eh? But her brother was well up to the front.

Did you see him come out on us?"

"Yes, I did."

"Did he ever strike you as being crazy--this brother of hers?"

"I can't say that he ever did."

"I dare say not. I always thought him sane enough until today, but you can take it from me that either he or I ought to be in a straitjacket.

What's the matter with me, anyhow? You've lived near me for some weeks, Watson. Tell me straight, now! Is there anything that would prevent me from making a good husband to a woman that I loved?"

"I should say not."

"He can't object to my worldly position, so it must be myself that he has this down on. What has he against me? I never hurt man or woman in my life that I know of. And yet he would not so much as let me touch the tips of her fingers."

"Did he say so?"

"That, and a deal more. I tell you, Watson, I've only known her these few weeks, but from the first I just felt that she was made for me, and she, too--she was happy when she was with me, and that I'll swear.

There's a light in a woman's eyes that speaks louder than words. But he has never let us get together and it was only today for the first time that I saw a chance of having a few words with her alone. She was glad to meet me, but when she did it was not love that she would talk about, and she wouldn't have let me talk about it either if she could have stopped it. She kept coming back to it that this was a place of danger, and that she would never be happy until I had left it. I told her that since I had seen her I was in no hurry to leave it, and that if she really wanted me to go, the only way to work it was for her to arrange to go with me. With that I offered in as many words to marry her, but before she could answer, down came this brother of hers, running at us with a face on him like a madman. He was just white with rage, and those light eyes of his were blazing with fury. What was I doing with the lady? How dared I offer her attentions which were distasteful to her?

Did I think that because I was a baronet I could do what I liked? If he had not been her brother I should have known better how to answer him.

As it was I told him that my feelings towards his sister were such as I was not ashamed of, and that I hoped that she might honour me by becoming my wife. That seemed to make the matter no better, so then I lost my temper too, and I answered him rather more hotly than I should perhaps, considering that she was standing by. So it ended by his going off with her, as you saw, and here am I as badly puzzled a man as any in this county. Just tell me what it all means, Watson, and I'll owe you more than ever I can hope to pay."

I tried one or two explanations, but, indeed, I was completely puzzled myself. Our friend's t.i.tle, his fortune, his age, his character, and his appearance are all in his favour, and I know nothing against him unless it be this dark fate which runs in his family. That his advances should be rejected so brusquely without any reference to the lady's own wishes and that the lady should accept the situation without protest is very amazing. However, our conjectures were set at rest by a visit from Stapleton himself that very afternoon. He had come to offer apologies for his rudeness of the morning, and after a long private interview with Sir Henry in his study the upshot of their conversation was that the breach is quite healed, and that we are to dine at Merripit House next Friday as a sign of it.

"I don't say now that he isn't a crazy man," said Sir Henry; "I can't forget the look in his eyes when he ran at me this morning, but I must allow that no man could make a more handsome apology than he has done."

"Did he give any explanation of his conduct?"

"His sister is everything in his life, he says. That is natural enough, and I am glad that he should understand her value. They have always been together, and according to his account he has been a very lonely man with only her as a companion, so that the thought of losing her was really terrible to him. He had not understood, he said, that I was becoming attached to her, but when he saw with his own eyes that it was really so, and that she might be taken away from him, it gave him such a shock that for a time he was not responsible for what he said or did.

He was very sorry for all that had pa.s.sed, and he recognized how foolish and how selfish it was that he should imagine that he could hold a beautiful woman like his sister to himself for her whole life. If she had to leave him he had rather it was to a neighbour like myself than to anyone else. But in any case it was a blow to him and it would take him some time before he could prepare himself to meet it. He would withdraw all opposition upon his part if I would promise for three months to let the matter rest and to be content with cultivating the lady's friendship during that time without claiming her love. This I promised, and so the matter rests."

So there is one of our small mysteries cleared up. It is something to have touched bottom anywhere in this bog in which we are floundering.

We know now why Stapleton looked with disfavour upon his sister's suitor--even when that suitor was so eligible a one as Sir Henry. And now I pa.s.s on to another thread which I have extricated out of the tangled skein, the mystery of the sobs in the night, of the tear-stained face of Mrs. Barrymore, of the secret journey of the butler to the western lattice window. Congratulate me, my dear Holmes, and tell me that I have not disappointed you as an agent--that you do not regret the confidence which you showed in me when you sent me down. All these things have by one night's work been thoroughly cleared.

I have said "by one night's work," but, in truth, it was by two nights'

work, for on the first we drew entirely blank. I sat up with Sir Henry in his rooms until nearly three o'clock in the morning, but no sound of any sort did we hear except the chiming clock upon the stairs. It was a most melancholy vigil and ended by each of us falling asleep in our chairs. Fortunately we were not discouraged, and we determined to try again. The next night we lowered the lamp and sat smoking cigarettes without making the least sound. It was incredible how slowly the hours crawled by, and yet we were helped through it by the same sort of patient interest which the hunter must feel as he watches the trap into which he hopes the game may wander. One struck, and two, and we had almost for the second time given it up in despair when in an instant we both sat bolt upright in our chairs with all our weary senses keenly on the alert once more. We had heard the creak of a step in the pa.s.sage.

Very stealthily we heard it pa.s.s along until it died away in the distance. Then the baronet gently opened his door and we set out in pursuit. Already our man had gone round the gallery and the corridor was all in darkness. Softly we stole along until we had come into the other wing. We were just in time to catch a glimpse of the tall, black-bearded figure, his shoulders rounded as he tiptoed down the pa.s.sage. Then he pa.s.sed through the same door as before, and the light of the candle framed it in the darkness and shot one single yellow beam across the gloom of the corridor. We shuffled cautiously towards it, trying every plank before we dared to put our whole weight upon it. We had taken the precaution of leaving our boots behind us, but, even so, the old boards snapped and creaked beneath our tread. Sometimes it seemed impossible that he should fail to hear our approach. However, the man is fortunately rather deaf, and he was entirely preoccupied in that which he was doing. When at last we reached the door and peeped through we found him crouching at the window, candle in hand, his white, intent face pressed against the pane, exactly as I had seen him two nights before.

We had arranged no plan of campaign, but the baronet is a man to whom the most direct way is always the most natural. He walked into the room, and as he did so Barrymore sprang up from the window with a sharp hiss of his breath and stood, livid and trembling, before us. His dark eyes, glaring out of the white mask of his face, were full of horror and astonishment as he gazed from Sir Henry to me.

"What are you doing here, Barrymore?"

"Nothing, sir." His agitation was so great that he could hardly speak, and the shadows sprang up and down from the shaking of his candle. "It was the window, sir. I go round at night to see that they are fastened."

"On the second floor?"

"Yes, sir, all the windows."

"Look here, Barrymore," said Sir Henry sternly, "we have made up our minds to have the truth out of you, so it will save you trouble to tell it sooner rather than later. Come, now! No lies! What were you doing at that window?"

The fellow looked at us in a helpless way, and he wrung his hands together like one who is in the last extremity of doubt and misery.

"I was doing no harm, sir. I was holding a candle to the window."

"And why were you holding a candle to the window?"

"Don't ask me, Sir Henry--don't ask me! I give you my word, sir, that it is not my secret, and that I cannot tell it. If it concerned no one but myself I would not try to keep it from you."

A sudden idea occurred to me, and I took the candle from the trembling hand of the butler.

"He must have been holding it as a signal," said I. "Let us see if there is any answer." I held it as he had done, and stared out into the darkness of the night. Vaguely I could discern the black bank of the trees and the lighter expanse of the moor, for the moon was behind the clouds. And then I gave a cry of exultation, for a tiny pinpoint of yellow light had suddenly transfixed the dark veil, and glowed steadily in the centre of the black square framed by the window.

"There it is!" I cried.

"No, no, sir, it is nothing--nothing at all!" the butler broke in; "I a.s.sure you, sir--"

"Move your light across the window, Watson!" cried the baronet. "See, the other moves also! Now, you rascal, do you deny that it is a signal?

Come, speak up! Who is your confederate out yonder, and what is this conspiracy that is going on?"

The man's face became openly defiant. "It is my business, and not yours.

I will not tell."

"Then you leave my employment right away."

"Very good, sir. If I must I must."
