“ But what did you learn to-night, Knox?”
I repeated Val Beverley’s story of the mysterious footsteps and of the cries which had twice awakened her in the night.
“Hm,” muttered Harley, when I had ceased speaking. “Assuming her account to be true——”
“Why should you doubt it?” I interrupted, hotly.
“My dear Knox, it is my business to doubt everything until I have indisputable evidence of its truth. I say, assuming her story to be true, we find ourselves face to face with the fantastic theory that some woman unknown is living secretly in Cray’s Folly.” ”

“ Evidently the door was locked, for he turned and swept the white ray all about the place. He tried several other doors, but found them all to be locked, for presently he came upstairs again, smiling grimly when he saw me there awaiting him.
“Did you hear it, Knox?” he said.
“A sound like the closing of a door?”
Paul Harley nodded.
“It was the closing of a door,” he replied; “but before that I had distinctly heard a stair creak. Someone crossed the hall then, Knox. Yet, as you perceive for yourself, it affords no hiding-place.” ”

My sight was now becoming used to the dusk, and I saw Harley vigorously shake his head.
“No, no,” he replied; “I have seen all the tower rooms. I can swear that no one inhabits them. Besides, is it feasible?”
“Then whose were the footsteps that Miss Beverley heard?”
“Obviously those of the woman who, at this present moment, so far as I know, is in the smoking-room with Colonel Menendez.” ”
