Still I knew that this phantom approach must be unknown to my companion—and I knew that it was impossible for me to advise him of it unseen by the dreaded visitor.
A third time the dark patch—the hand of one who, ghostly, silent, was creeping down into the hallway—vanished and reappeared on a level with my eyes. Then a vague shape became visible; no more than a blur upon the dim design of the wall-paper... and Nayland Smith got his first sight of the stranger.
The clock on the mantelpiece boomed out the half-hour.
At that, such was my state (I blush to relate it) I uttered a faint cry!
It ended all secrecy—that hysterical weakness of mine. It might have frustrated our hopes; that it did not do so was in no measure due to me. But in a sort of passionate whirl, the ensuing events moved swiftly.
Smith hesitated not one instant. With a panther-like leap he hurled himself into the hall.
“The lights, Petrie!” he cried—“the lights! The switch is near the street-door!”
I clenched my fists in a swift effort to regain control of my treacherous nerves, and, bounding past Smith, and past the foot of the stair, I reached out my hand to the switch, the situation of which, fortunately, I knew.
Around I came, in response to a shrill cry from behind me—an inhuman cry, less a cry than the shriek of some enraged animal....
With his left foot upon the first stair, Nayland Smith stood, his lean body bent perilously backward, his arms rigidly thrust out, and his sinewy fingers gripping the throat of an almost naked man—a man whose brown body glistened unctuously, whose shaven head was apish low, whose bloodshot eyes were the eyes of a mad dog! His teeth, upper and lower, were bared; they glistened, they gnashed, and a froth was on his lips. With both his hands, he clutched a heavy stick, and once—twice, he brought it down upon Nayland Smith’s head!
