"You"re mighty close about this affair, Mr. Holmes. What"s the game now?"
"A waiting game."
"My word, it does not seem a very cheerful place," said the detective with a shiver, glancing round him at the gloomy slopes of the hill and at the huge lake of fog which lay over the Grimpen Mire. "I see the lights of a house ahead of us."
"That is Merripit House and the end of our journey. I must request you to walk on tiptoe and not to talk above a whisper."
We moved cautiously along the track as if we were bound for the house, but Holmes halted us when we were about two hundred yards from it.
"This will do," said he. "These rocks upon the right make an admirable screen."
"We are to wait here?"
"Yes, we shall make our little ambush here. Get into this hollow, Lestrade. You have been inside the house, have you not, Watson? Can you tell the position of the rooms? What are those latticed windows at this end?"
"I think they are the kitchen windows."
"And the one beyond, which shines so brightly?"
"That is certainly the dining-room."
"The blinds are up. You know the lie of the land best. Creep forward quietly and see what they are doing--but for heaven"s sake don"t let them know that they are watched!"
I tiptoed down the path and stooped behind the low wall which surrounded the stunted orchard. Creeping in its shadow I reached a point whence I could look straight through the uncurtained window.
There were only two men in the room, Sir Henry and Stapleton. They sat with their profiles towards me on either side of the round table. Both of them were smoking cigars, and coffee and wine were in front of them.
Stapleton was talking with animation, but the baronet looked pale and distrait. Perhaps the thought of that lonely walk across the ill-omened moor was weighing heavily upon his mind.
As I watched them Stapleton rose and left the room, while Sir Henry filled his gla.s.s again and leaned back in his chair, puffing at his cigar. I heard the creak of a door and the crisp sound of boots upon gravel. The steps pa.s.sed along the path on the other side of the wall under which I crouched. Looking over, I saw the naturalist pause at the door of an out-house in the corner of the orchard. A key turned in a lock, and as he pa.s.sed in there was a curious scuffling noise from within. He was only a minute or so inside, and then I heard the key turn once more and he pa.s.sed me and reentered the house. I saw him rejoin his guest, and I crept quietly back to where my companions were waiting to tell them what I had seen.
"You say, Watson, that the lady is not there?" Holmes asked when I had finished my report.
"No."
"Where can she be, then, since there is no light in any other room except the kitchen?"
"I cannot think where she is."
I have said that over the great Grimpen Mire there hung a dense, white fog. It was drifting slowly in our direction and banked itself up like a wall on that side of us, low but thick and well defined. The moon shone on it, and it looked like a great shimmering ice-field, with the heads of the distant tors as rocks borne upon its surface. Holmes"s face was turned towards it, and he muttered impatiently as he watched its sluggish drift.
"It"s moving towards us, Watson."
"Is that serious?"
"Very serious, indeed--the one thing upon earth which could have disarranged my plans. He can"t be very long, now. It is already ten o"clock. Our success and even his life may depend upon his coming out before the fog is over the path."
The night was clear and fine above us. The stars shone cold and bright, while a half-moon bathed the whole scene in a soft, uncertain light.
Before us lay the dark bulk of the house, its serrated roof and bristling chimneys hard outlined against the silver-spangled sky. Broad bars of golden light from the lower windows stretched across the orchard and the moor. One of them was suddenly shut off. The servants had left the kitchen. There only remained the lamp in the dining-room where the two men, the murderous host and the unconscious guest, still chatted over their cigars.
Every minute that white woolly plain which covered one-half of the moor was drifting closer and closer to the house. Already the first thin wisps of it were curling across the golden square of the lighted window.
The farther wall of the orchard was already invisible, and the trees were standing out of a swirl of white vapour. As we watched it the fog-wreaths came crawling round both corners of the house and rolled slowly into one dense bank on which the upper floor and the roof floated like a strange ship upon a shadowy sea. Holmes struck his hand pa.s.sionately upon the rock in front of us and stamped his feet in his impatience.
"If he isn"t out in a quarter of an hour the path will be covered. In half an hour we won"t be able to see our hands in front of us."
"Shall we move farther back upon higher ground?"
"Yes, I think it would be as well."
So as the fog-bank flowed onward we fell back before it until we were half a mile from the house, and still that dense white sea, with the moon silvering its upper edge, swept slowly and inexorably on.
"We are going too far," said Holmes. "We dare not take the chance of his being overtaken before he can reach us. At all costs we must hold our ground where we are." He dropped on his knees and clapped his ear to the ground. "Thank G.o.d, I think that I hear him coming."
A sound of quick steps broke the silence of the moor. Crouching among the stones we stared intently at the silver-tipped bank in front of us.
The steps grew louder, and through the fog, as through a curtain, there stepped the man whom we were awaiting. He looked round him in surprise as he emerged into the clear, starlit night. Then he came swiftly along the path, pa.s.sed close to where we lay, and went on up the long slope behind us. As he walked he glanced continually over either shoulder, like a man who is ill at ease.
"Hist!" cried Holmes, and I heard the sharp click of a c.o.c.king pistol.
"Look out! It"s coming!"
There was a thin, crisp, continuous patter from somewhere in the heart of that crawling bank. The cloud was within fifty yards of where we lay, and we glared at it, all three, uncertain what horror was about to break from the heart of it. I was at Holmes"s elbow, and I glanced for an instant at his face. It was pale and exultant, his eyes shining brightly in the moonlight. But suddenly they started forward in a rigid, fixed stare, and his lips parted in amazement. At the same instant Lestrade gave a yell of terror and threw himself face downward upon the ground.
I sprang to my feet, my inert hand grasping my pistol, my mind paralyzed by the dreadful shape which had sprung out upon us from the shadows of the fog. A hound it was, an enormous coal-black hound, but not such a hound as mortal eyes have ever seen. Fire burst from its open mouth, its eyes glowed with a smouldering glare, its muzzle and hackles and dewlap were outlined in flickering flame. Never in the delirious dream of a disordered brain could anything more savage, more appalling, more h.e.l.lish be conceived than that dark form and savage face which broke upon us out of the wall of fog.
With long bounds the huge black creature was leaping down the track, following hard upon the footsteps of our friend. So paralyzed were we by the apparition that we allowed him to pa.s.s before we had recovered our nerve. Then Holmes and I both fired together, and the creature gave a hideous howl, which showed that one at least had hit him. He did not pause, however, but bounded onward. Far away on the path we saw Sir Henry looking back, his face white in the moonlight, his hands raised in horror, glaring helplessly at the frightful thing which was hunting him down. But that cry of pain from the hound had blown all our fears to the winds. If he was vulnerable he was mortal, and if we could wound him we could kill him. Never have I seen a man run as Holmes ran that night. I am reckoned fleet of foot, but he outpaced me as much as I outpaced the little professional. In front of us as we flew up the track we heard scream after scream from Sir Henry and the deep roar of the hound. I was in time to see the beast spring upon its victim, hurl him to the ground, and worry at his throat. But the next instant Holmes had emptied five barrels of his revolver into the creature"s flank. With a last howl of agony and a vicious snap in the air, it rolled upon its back, four feet pawing furiously, and then fell limp upon its side. I stooped, panting, and pressed my pistol to the dreadful, shimmering head, but it was useless to press the trigger. The giant hound was dead.
Sir Henry lay insensible where he had fallen. We tore away his collar, and Holmes breathed a prayer of grat.i.tude when we saw that there was no sign of a wound and that the rescue had been in time. Already our friend"s eyelids shivered and he made a feeble effort to move. Lestrade thrust his brandy-flask between the baronet"s teeth, and two frightened eyes were looking up at us.
"My G.o.d!" he whispered. "What was it? What, in heaven"s name, was it?"
"It"s dead, whatever it is," said Holmes. "We"ve laid the family ghost once and forever."
In mere size and strength it was a terrible creature which was lying stretched before us. It was not a pure bloodhound and it was not a pure mastiff; but it appeared to be a combination of the two--gaunt, savage, and as large as a small lioness. Even now in the stillness of death, the huge jaws seemed to be dripping with a bluish flame and the small, deep-set, cruel eyes were ringed with fire. I placed my hand upon the glowing muzzle, and as I held them up my own fingers smouldered and gleamed in the darkness.
"Phosphorus," I said.
"A cunning preparation of it," said Holmes, sniffing at the dead animal.
"There is no smell which might have interfered with his power of scent.
We owe you a deep apology, Sir Henry, for having exposed you to this fright. I was prepared for a hound, but not for such a creature as this.
And the fog gave us little time to receive him."
"You have saved my life."
"Having first endangered it. Are you strong enough to stand?"
"Give me another mouthful of that brandy and I shall be ready for anything. So! Now, if you will help me up. What do you propose to do?"
"To leave you here. You are not fit for further adventures tonight. If you will wait, one or other of us will go back with you to the Hall."
He tried to stagger to his feet; but he was still ghastly pale and trembling in every limb. We helped him to a rock, where he sat shivering with his face buried in his hands.
