It disappeared for a full minute, then flickered in the bedroom that adjoined the study.
At last, it was back in the large room. It shone on the floor — at the very place where Silas Harshaw’s dead body had been found.
The silvery radiator glittered as the light ran along it. Then the gleaming torch made a small spot that zigzagged along the sill.
It disappeared and left no trace. The Shadow had returned to the gloom of the room.
Now he was below the window sill, a crouching figure, stooping as Silas Harshaw might have stooped, the night he met his doom.
For one fraction of a second, the light again glimmered on the floor. Then it was no longer visible.
The cause of its disappearance was a muffled sound that had occurred outside the window.
There was a slight crackling; the noise of metal driven into wood. The Shadow arose and stood beside the window.
SOME one was moving against the iron grating!
The window was a dim frame that provided very little relief from the blackness of the room, but now the vague outline of a man was visible there.
