"We must risk it!" said Carneta steadily. "There are French windows opening on to that verandah. Ten yards farther around the bushes come right up to the wall of the house. We'll go that way and around by the other wing on to the verandah."
Any action was preferable to this nerve-sapping delay, and with a determination to shoot, and shoot to kill, any one who opposed our entrance, I passed through the bushes and, with Carneta, rounded the southern border of that silent house and slipped quietly on to the verandah.
Kneeling, Carneta opened the knapsack. My eyes were growing accustomed to the darkness, and I was just able to see her deft hands at work upon the fastenings. She made no noise, and I watched her with an ever-growing wonder. A female burglar is a personage difficult to imagine. Certainly, no one ever could have suspected this girl with the violet eyes of being an expert crackswoman; but of her efficiency there could be no question. I think I had never witnessed a more amazing spectacle than that of this cultured girl manipulating the tools of the house breaker with her slim white fingers.
Suddenly she turned and clutched my arm.
"The windows are not fastened!" she whispered.
A strange courage came to me — perhaps that of desperation. For, ignoring the ominous circumstance, I pushed open the nearest window and stepped into the room beyond! A hissing breath from Carneta acknowledged my performance, and she entered close behind me, silent in her rubber-soled shoes.
For one thrilling moment we stood listening. Then came the white beam from the electric lamp to cut through the surrounding blackness.
The room was totally unfurnished!
Chapter 31
THE POOL OF DEATH
Not a sound broke the stillness of the Gate House. It was the most eerily silent place in which I had ever found myself. Out into the corridor we went, noiselessly. It was stripped, uncarpeted.
Three doors we passed, two upon the left and one upon the right. We tried them all. All were unfastened, and the rooms into which they opened bare and deserted. Then we came upon a short, descending stair, at its foot a massive oaken door.
Carneta glided down, noiseless as a ghost, and to one of the blackened panels applied an ingenious little instrument which she carried in her knapsack. It was not unlike a stethoscope; and as I watched her listening, by means of this arrangement, for any sound beyond the oaken door, I reflected how almost every advance made by science places a new tool in the hand of the criminal.
No word had been spoken since we had discovered this door; none had been necessary. For we both knew that the place beyond was that from which proceeded the mysterious red light.
I directed the ray of the electric torch upon Carneta, as she stood there listening, and against that sombre oaken background her face and profile stood out with startling beauty. She seemed half perplexed and half fearful. Then she abruptly removed the apparatus, and, stooping to the knapsack, replaced it and took out a bunch of wire keys, signing to me to hand her the lamp.
As I crept down the steps I saw her pause, glancing back over her shoulder toward the door. The expression upon her face induced me to direct the light in the same direction.
Why neither of us had observed the fact before I cannot conjecture; but a key was in the lock!
Perhaps the traffic of the night afforded no more dramatic moment than this. The house which we were come prepared burglariously to enter was thrown open, it would seem, to us, inviting our inspection!
Looking back upon that moment, it seems almost incredible that the sight of a key in a lock should have so thrilled me. But at the time I perceived something sinister in this failure of the Lord of the Hashishin to close his doors to intruders. That Carneta shared my doubts and fears was to be read in her face; but her training had been peculiar, I learned, and such as establishes a surprising resoluteness of character.
Quite noiselessly she turned the key, and holding a dainty pocket revolver in her hand, pushed the door open slowly!
An odour, sickly sweet and vaguely familiar, was borne to my nostrils. Carneta became outlined in dim, reddish light. Bending forward slightly, she entered the room, and I, with muscles tensed nervously, advanced and stood beside her.
I perceived that this was a cellar; indeed, I doubt not that in some past age it had served as a dungeon. From the stone roof hung the first evidence of Eastern occupation which the Gate House had yielded; in the form of an Oriental lantern, or fanoos, of rose-coloured waxed paper upon a copper frame. Its vague light revealed the interior of the hideous place upon whose threshold we stood.
Straight before us, deep set in the stone wall, was the tiny square window, iron-barred without, and glazed with red glass, the light from which had so deeply mystified us. Within a niche in the wall, a little to the left of the window, rested an object which, at that moment, claimed our undivided attention the sight of which so wrought upon us that temporarily all else was forgotten.
It was the red slipper of the Prophet!
"My God!" whispered Carneta—"my God!" — and clutched at me, swaying dizzily.
A few inches from our feet the floor became depressed, how deeply I could not determine, for it was filled with water, water filthy and slimy! The strange, nauseating odour had grown all but unsupportable; it seemingly proceeded from this fetid pool which, occupying the floor of the dungeon, offered a barrier, since its depth was unknown, of fully twelve feet between ourselves and the farther wall.
There was a faint, dripping sound: a whispering, echoing drip-drip of falling water. I could not tell from whence it proceeded.
Almost supporting my companion, whose courage seemed suddenly to have failed her, I stared fascinatedly at that blood-stained relic. Something then induced me to look behind; I suppose a warning instinct of that sort which is unexplainable. I only know that upholding Carneta with my left arm, and nervously grasping my revolver in my right, I turned and glanced over my shoulder.
Very slowly, but with a constant, regular motion, the massive door was closing!
I snatched away my arm; in my left hand I held the electric torch, and springing sharply about I directed the searching ray into the black gap of the stairway. A yellow face, a malignant Oriental face, came suddenly, fully, into view! Instantly I recognized it for that of the man who had driven Hassan's car!
Acting upon the determination with which I had entered the Gate House, I raised my revolver and fired straight between the evil eyes! To the fact that I dropped my left hand in the act of pulling the trigger with my right, and thus lost my mark, the servant of Hassan of Aleppo owed his escape. I missed him. He uttered a shrill cry of fear and went racing up the wooden stair. I followed him with the light and fired twice at the retreating figure. I heard him stumble and a second time cry out. But, though I doubt not he was hit, he recovered himself, for I heard his tread in the corridor above.
Propping wide the door with my foot, I turned to Carneta. Her face was drawn and haggard; but her mouth set in a sort of grim determination.
"Earl is dead!" she said, in a queer, toneless voice. "He died trying to get — that thing! I will get it, and destroy it!"
Before I could detain her, even had I sought to do so, she stepped into the filthy water, struggled to recover her foothold, and sank above her waist into its sliminess. Without hesitation she began to advance toward the niche which contained the slipper. In the middle of the pool she stopped.
What memory it was which supplied the clue to the identity of that nauseating smell, heaven alone knows; but as the girl stopped and drew herself up rigidly — then turned and leapt wildly back toward the door — I knew what occasioned that sickly odour!
