Within my view, from the corner of the room where I sat in deepest shadow, through the partly opened window (it was screwed, like our own) were rows of glass-houses gleaming in the moonlight, and, beyond them, orderly ranks of flower-beds extending into a blue haze of distance. By reason of the moon's position, no light entered the room, but my eyes, from long watching, were grown familiar with the darkness, and I could see Burke quite clearly as he lay in the bed between my post and the window. I seemed to be back again in those days of the troubled past when first Nayland Smith and I had come to grips with the servants of Dr. Fu-Manchu. A more peaceful scene than this flower-planted corner of Essex it would be difficult to imagine; but, either because of my knowledge that its peace was chimerical, or because of that outflung consciousness of danger which actually, or in my imagination, preceded the coming of the Chinaman's agents, to my seeming the silence throbbed electrically and the night was laden with stilly omens.  
Already cramped by my journey in the market-cart, I found it difficult to remain very long in any one position. What information had Burke to sell? He had refused, for some reason, to discuss the matter that evening, and now, enacting the part allotted him by Nayland Smith, he feigned sleep consistently, although at intervals he would whisper to me his doubts and fears.
[125]
 
All the chances were in our favour to-night; for whilst I could not doubt that Dr. Fu-Manchu was set upon the removal of the ex-officer of New York police, neither could I doubt that our presence in the farm was unknown to the agents of the Chinaman. According to Burke, constant attempts had been made to achieve Fu-Manchu's purpose, and had only been frustrated by his (Burke's) wakefulness. There was every probability that another attempt would be made to-night.
 
Any one who has been forced by circumstance to undertake such a vigil as this will be familiar with the marked changes (corresponding with phases of the earth's movement) which take place in the atmosphere, at midnight, at two o'clock, and again at four o'clock. During those four hours falls a period wherein all life is at its lowest ebb, and every physician is aware that there is a greater likelihood of a patient's passing between midnight and 4 a.m., than at any other period during the cycle of the hours.
 
To-night I became specially aware of this lowering of vitality, and now, with the night at that darkest phase which precedes the dawn, an indescribable dread, such as I had known before in my dealings with the Chinaman, assailed me, when I was least prepared to combat it. The stillness was intense Then:
 
"Here it is!" whispered Burke from the bed.
 
The chill at the very centre of my being, which but corresponded with the chill of all surrounding nature at that hour, became intensified, keener, at the whispered words.
 
I rose stealthily out of my chair, and from my nest of shadows watched—watched intently, the bright oblong of the window....
 
Without the slightest heralding sound—a black silhouette crept up against the pane ... the silhouette of a small, malformed head, a dog-like head,
[126]
deep-set in square shoulders. Malignant eyes peered intently in. Higher it rose—that wicked head—against the window, then crouched down on the sill and became less sharply defined as the creature stooped to the opening below. There was a faint sound of sniffing.
 
Judging from the stark horror which I experienced myself, I doubted, now, if Burke could sustain the rôle allotted him. In beneath the slightly raised window came a hand, perceptible to me despite the darkness of the room. It seemed to project from the black silhouette outside the pane, to be thrust forward—and forward—and forward ... that small hand with the outstretched fingers.
 
The unknown possesses unique terrors; and since I was unable to conceive what manner of thing this could be, which, extending its incredibly long arms, now sought the throat of the man upon the bed, I tasted of that sort of terror which ordinarily one knows only in dreams.
 
"Quick, sir—quick!" screamed Burke, starting up from the pillow.
 
The questing hands had reached his throat!
 
Choking down an urgent dread that I had of touching the thing which had reached through the window to kill the sleeper, I sprang across the room and grasped the rigid, hairy forearms.
 
Heavens! Never have I felt such muscles, such tendons, as those beneath the hirsute skin! They seemed to be of steel wire, and with a sudden frightful sense of impotence, I realized that I was as powerless as a child to relax that strangle-hold. Burke was making the most frightful sounds and quite obviously was being asphyxiated before my eyes!
 
"Smith!" I cried, "Smith! Help! help! for God's sake!"
 
Despite the confusion of my mind I became aware of sounds outside and below me. Twice the thing at the window coughed; there was an incessant,
[127]
lash-like cracking, then some shouted words which I was unable to make out; and finally the sharp report of a pistol.
 
Snarling like that of a wild beast came from the creature with the hairy arms, together with renewed coughing. But the steel grip relaxed not one iota. I realized two things: the first, that in my terror at the suddenness of the attack I had omitted to act as prearranged: the second, that I had discredited the strength of the visitant, whilst Smith had foreseen it.
 
Desisting in my vain endeavour to pit my strength against that of the nameless thing, I sprang back across the room and took up the weapon which had been left in my charge earlier in the night, but which I had been unable to believe it would be necessary to employ. This was a sharp and heavy axe which Nayland Smith, when I had met him............
