“What was it?” said Hugh, affected by her fear with the horror of the unknown.  But she made no answer, and continued staring towards one of the windows.  He rose and was about to advance to it, when she caught him by the hand with a grasp of which hers would have been incapable except under the influence of terror.  At that moment a clock in the room began to strike.  It was a slow clock, and went on deliberately, striking one...two...three...till it had struck twelve.  Every stroke was a blow from the hammer of fear, and his heart was the bell.  He could not breathe for dread so long as the awful clock was striking.  When it had ended, they looked at each other again, and Hugh breathed once.

“Euphra!” he sighed.

But she made no answer; she turned her eyes again to one of the windows.  They were both standing.  He sought to draw her to him, but she yielded no more than a marble statue.

“I crossed the Ghost’s Walk to-night,” said he, in a hard whisper, scarcely knowing that he uttered it, till he heard his own words.  They seemed to fall upon his ear as if spoken by some one outside the room.  She looked at him once more, and kept looking with a fixed stare.  Gradually her face became less rigid, and her eyes less wild.  She could move at last.

“Come, come,” she said, in a hurried whisper.  “Let us go —­ no, no, not that way;” —­ as Hugh would have led her towards the private stair —­ “let us go the front way, by the oak staircase.”

They went up together.  When they reached the door of her room, she said, “Good night,” without even looking at him, and passed in.  Hugh went on, in a state of utter bewilderment, to his own apartment; shut the door and locked it —­ a thing he had never done before; lighted both the candles on his table; and then walked up and down the room, trying, like one aware that he is dreaming, to come to his real self.

“Pshaw!” he said at last.  “It was only a little bird, or a large moth.  How odd it is that darkness can make a fool of one!  I am ashamed of myself.  I wish I had gone out at the window, if only to show Euphra I was not afraid, though of course there was nothing to be seen.”

As he said this in his mind, —­ he could not have spoken it aloud, for fear of hearing his own voice in the solitude, —­ he went to one of the windows of his sitting-room, which was nearly over the library, and looked into the wood. —­ Could it be? —­ Yes. —­ He did see something white, gliding through the wood, away in the direction of the Ghost’s Walk.  It vanished; and he saw it no more.
