Without the slightest heralding sound—a black silhouette crept up against the pane ... the silhouette of a small, malformed head, a dog-like head, 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, 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.
