"It is morning again," he said. "How have you passed the night, my handsome doctor? I see the rodents have not eaten you. I shouldn't have been the least surprised if they had. I assure you, I wonder they could have abstained from such a feast."

"You fiend incarnate!" cried Jay Gardiner, hoarsely. "Remove these shackles, and meet me as man to man. Only a dastardly coward bullies a man who can not help himself."

"Still defiant, my charming doctor!" laughed Wilde. "I marvel at that. I supposed by this time you would be quite willing to give me the information I desired."

Jay Gardiner could not trust himself to speak, his indignation was so great.

"Au revoir again," sneered Wilde. "The day will pass and the night will follow, in the natural course of events. To-morrow, at this hour, I shall look in on you again, my handsome doctor. Look out for the rodents. Bless me! they are dashing over the floor. I must fly!"

Again the door closed, and with a groan Jay Gardiner could not repress, he sunk to the floor, smiting it with his manacled hands, and wondering how soon this awful torture would end.

CHAPTER XXIX.

During the long hours of the night which followed, Jay Gardiner dared not trust himself to sleep for a single instant, so great was his horror of the rodents that scampered in droves across the damp floor of the cellar in which he was a prisoner.

He felt that his brain must soon give way, and that Jasper Wilde would have his desire—he would soon be driven to insanity.

He thought of Bernardine, who was waiting for him to return to her, and he groaned aloud in the bitterness of his anguish, in the agony of his awful despair.
