The faint disturbance faded into silence again. Across the dead man's body I met Smith's gaze. Faint wreaths of fog floated in from the outer room. Beeton clutched the foot of the bed, and the structure shook in sympathy with his wild trembling. That was the only sound now; there was absolutely nothing physical so far as my memory serves to signalize the coming of the brown man.
Yet, stealthy as his approach had been, something must have warned us. For suddenly, with one accord, we three turned upon the bed, and stared out into the room from which the fog wreaths floated in.
Beeton stood nearest to the door, but, although he turned, he did not go out, but with a smothered cry crouched back against the bed. Smith it was who moved first, then I followed, and close upon his heels burst into the disordered sitting-room. The outer door had been closed but not bolted, and what with the tinted light, diffused through the silken Japanese shade, and the presence of fog in the room, I was almost tempted to believe myself the victim of a delusion. What I saw or thought I saw was this:—
A tall screen stood immediately inside the door, and around its end, like some materialization of the choking mist, glided a lithe, yellow figure, a slim, crouching figure, wearing a sort of loose robe. An impression I had of jet-black hair, protruding from beneath a little cap, of finely chiseled features and great, luminous eyes, then, with no sound to tell of a door opened or shut, the apparition was gone.
"You saw him, Petrie!—you saw him!" cried Smith.
In three bounds he was across the room, had tossed the screen aside and thrown open the door. Out he sprang into the yellow haze of the corridor, tripped, and, uttering a cry of pain, fell sprawling upon the marble floor. Hot with apprehension I joined him, but he looked up with a wry smile and began furiously rubbing his left shin.
"A queer trick, Petrie," he said, rising to his feet; "but nevertheless effective."
He pointed to the object which had occasioned his fall. It was a small metal chest, evidently of very considerable weight, and it stood immediately outside the door of Number 14a.
"That was what he came for, sir! That was what he came for! You were too quick for him!"
Beeton stood behind us, his horror-bright eyes fixed upon the box.
