<h3> CHAPTER XVIII </h3>
<h3> WHAT CAME THROUGH THE WINDOW </h3>
<p>I had not been in my unnatural position for many minutes before I
began to suffer agonies, agonies not only physical but mental; for
standing there like some prisoner of the Inquisition, it came to me
how this dismantled apartment must be the focus of the dreadful
forces of Hassan of Aleppo!</p>
<p>That Earl Dexter had the slipper of the Prophet I no longer doubted,
and that he had sustained, in this dwelling beneath the roof, an
uncanny siege during the days which had passed since the theft from
the Antiquarian Museum, was equally certain. Helpless, gagged, I
pictured those hideous creatures, evil products of the secret East,
who might, nay, who must surround that place! I thought of the
horrible little yellow man who lay dead in Wyatt's Buildings; and
it became evident to me that the house in which I was now imprisoned
must overlook the back of those unsavoury tenements. The windows,
sack-covered now, no doubt commanded a view of the roofs of the
buildings. One of the mysteries that had puzzled us was solved. It
was Earl Dexter who had shot the yellow dwarf as he was bound for
this very room! But how humanly the Hashishin had proposed to gain
his goal, how he had travelled through empty space—for from empty
space the shot had brought him down—I could not imagine.</p>
<p>I knew something of the almost supernatural attributes of these
people. From Professor Deeping's book I knew of the incredible
feats which they could perform when under the influence of the drug
hashish. From personal experience also I knew that they had powers
wholly abnormal.</p>
<p>The pain in my arms and back momentarily increased. An awesome
silence ruled. I tortured myself with pictures of murderous
yellow men possessed of the power claimed by the Mahatmas, of
levitation. Mentally I could see a distorted half-animal creature
carrying a great gleaming knife and floating supernaturally toward
me through the night!</p>
<p>A soft pattering sound became perceptible on the sloping roof above!</p>
<p>I think I have never known such intense and numbing fear as that
which now descended upon me. Perhaps I may be forgiven it. A more
dreadful situation it would be hard to devise. Knowing that I was
on the fifth story of a house, bound, helpless, I knew, too, that a
second mystic guardian of the slipper was come to accomplish the
task in which the first had failed!</p>
<p>I began to pray fervently.</p>
<p>Neither of the windows were closed; and now through the intense
darkness I heard one of them being raised up—up—up...</p>
<p>The sacking was pulled aside inch by inch.</p>
<p>Silhouetted against the faintly luminous background I saw a hunched,
unnatural figure. The real was more dreadful even than the
imaginary—for some stray beam of light touched into cold radiance
a huge curved knife which the visitant held between his teeth!</p>
<p>My fear became a madness, and I twisted my body violently in a wild
endeavour to free myself. A dreadful pain shot through my left
shoulder, and the whole nightmare scene—the thing with the knife
at the window—the low-ceiled room-began to fade away from me. I
seemed to be falling into deep water.</p>
<p>A splintering crash and the sound of shouting formed my last
recollections ere unconsciousness came.</p>
<p>I found myself lying in an armchair with Bristol forcing brandy
between my lips. My left arm hung limply at my side and the pain
in my dislocated shoulder was excruciating.</p>
<p>"Thank God you are all right, Mr. Cavanagh!" said the inspector.
"I got the surprise of my life when we smashed the door in and
found you tied up here!"</p>
<p>"You came none too soon," I said feebly. "God knows how Providence
directed you here."</p>
<p>"Providence it was," replied Bristol. "From the roof of Wyatt's
Buildings—you know the spot?—I saw the second yellow devil
coming. By God! They meant to have it to-night! They don't value
their lives a brass farthing against that damned slipper!"</p>
<p>"But how—"</p>
<p>"Along the telegraph-wires, Mr. Cavanagh! They cross Wyatt's
Buildings and cross this house. It was a moonless night or we
should have seen it at once! I watched him, saw him drop to this
roof—and brought the men around to the front."</p>
<p>"Did he, that awful thing, escape?"</p>
<p>"He dropped full forty feet into a tree—from the tree to the
ground, and went off like a cat!"</p>
<p>"Earl Dexter has escaped us," I said, "and he has the slipper!"</p>
<p>"God help him!" replied Bristol. "For by now he has that hell-pack
at his heels! What a case! Heavens above, it will drive me mad!"</p>
