It was empty.
Nothing but a heap of dust met his gaze.
"Come," he said, shortly, picking up the lantern and producing the key from his pocket; "there are rooms below and above. Let us examine them all, and see if we can find trace of her ghostship there."
He unlocked the door and led the way out into the deserted hall.
To the right and left opened other doors, connecting with the various chambers upon the floor.
Opening each in turn, Callister and his companion examined the rooms in silence.
One was a large guest chamber, containing various articles of antique furniture; another was a small bedroom, entirely vacant, and another still a bath-room, filled with rubbish of various kinds.
In neither one nor the other was there the slightest trace of the form of the woman which had appeared before them, nor evidence that the dust which covered everything had been disturbed for years.
Nor was their examination of the floor above better rewarded.
Here piles of old lumber were found, broken furniture, boxes, and bales.
