"Sybilla," hissed rather than spoke de Retz, "is it true that ever since by the lakeside of Carlinwark you met the Earl of Douglas you have deceived him and sought his doom?"

"I care not to hear the answer," said the young man, "even did I believe that which you by your power may compel her to say. Unfaith in another is not unfaith in me. I am bound to this lady in love and honour—aye, even unto death, if that be her will!"

"I have, indeed, deceived him!" replied the girl, slowly, the words seeming to be forced from her one by one.

"You hear, William of Douglas!" said the marshal, turning upon the young man, who stood still and motionless, never taking his eyes off the slender figure in white.

The marshal continued his pitiless questioning.

"At Castle Thrieve you persuaded him to follow you to Crichton and afterwards to Edinburgh, knowing well that you brought him to his death."

"It is true!" said the girl, with a voice like one speaking out of the grave itself.

"You hear, William of Douglas!" said the marshal.

"And at Castle Crichton you played the play to the end. With false cozening words you deceived this young man. You led him on with love on your lips and hate in your heart. You kissed him with the Judas kiss. You led his soul captive to death by the drawing of your eyes."

In a voice that could hardly be heard the girl replied, her whole figure fixed and turned to stone by the intensity of her tormentor's gaze.
