At this moment a terrible voice from behind the curtain exclaimed, "Sign, or Auriol is lost for ever."

"I cannot yield my soul, even to save him," cried Ebba distractedly.

"Witness his chastisement, then," cried the voice.

And as the words were uttered, a side door was opened on the opposite side, and Auriol was dragged forth from it by two masked personages, who looked like familiars of the Inquisition.

"Do not yield to the demands of this fiend, Ebba!" cried Auriol, gazing at her distractedly.

"Will you save him before he is cast, living, into the tomb?" cried the voice.

And at the words, a heavy slab of marble rose slowly from the floor near where Ebba sat, and disclosed a dark pit beneath.

Ebba gazed into the abyss with indescribable terror.

"There he will be immured, unless you sign," cried the voice; "and, as he is immortal, he will endure an eternity of torture."

"I cannot save him so, but I may precede him," cried Ebba. And throwing her hands aloft, she flung herself into the pit.
