"Ha! Ha! Ha! I have it! It is mine! The Wizard never fails!"

His laugh of joy had scarcely died away, before he uttered a most terrific shriek, and threw the phial from him, crying:

"Empty! Great G.o.d! It is empty!"

He stood silent and motionless for a moment. Then his eyes turned in the direction of Mr. Barnes, and he glared at him in such a way that the detective felt uncomfortable. Suddenly he burst forth with a tirade of abusive language.

"You! You are the cause of all this! You are the prying miscreant that has made all my trouble! I will have your life! I will drag you into the crypt of my great ancestor, and tear out your heart on the stone of sacrifice that still exists in there!"

He dashed forward with such force that the chains, reaching their limit suddenly, jerked him back so violently that he fell. As he did so his hand chanced to touch the hammer, which he had laid aside while trying to secure the bottle. With a shriek of joy that made Mr. Barnes shiver, he sprang up, holding the hammer aloft.

"I am chained! Chained! But you shall not escape! Take that!"

Swiftly he hurled the hammer, but Mr. Barnes, suspecting his purpose, dropped to his knees, and the missile went harmlessly over his head.

"Balked! Balked! I have failed! But I am the Wizard and I will succeed! Ha! Ha! Ha!" His laugh now filled the room. "You wonder how!

I am chained and you think that you are safe! Ha! Ha! Ha! You are a fool! You do not know me! I am Emanuel Medjora! I am powerful. I will rend these chains, and then your life shall pay!"

He turned, and wrapping the chains around his two arms, he braced his feet against the floor, and tugged with all his might.

He pulled, and swayed from side to side. He savagely jerked the chains, and then again he grasped one with both hands, but his efforts appeared to be in vain. But so much power did he display, that, as his back was turned, Mr. Barnes decided that it would be safer to prepare for flight. He therefore cautiously advanced towards the door, and there paused, ready, however, to dart out on the instant should it be necessary.

Still the Doctor tugged and jerked and rattled the chains, shrieking and laughing demoniacally at intervals. Presently, with a shout of triumph, he did burst one of the chains. Turning towards Mr. Barnes, he shouted:

"You see! I am the Wizard! I do what I please! You did not think that I could break it! Ha! Ha! Ha! You do not know Emanuel Medjora! He accomplishes what he wills! The will controls the muscles, and the mind controls the will! But now through my brain a liquid fire courses that makes my mind doubly powerful! I feel that I am getting stronger every moment! In another second I will snap this last chain as easily as you would break a cord! Then, then,--Ha! Ha! Ha! I'll have your heart out! Ha! Ha! Ha! I have an idea! I'll kill you now!"

He rushed forward as far as the remaining chain would permit, and extending the other arm, to which dangled the end of the chain which he had broken, he drew it back and then switched the dangling links viciously towards Mr. Barnes, narrowly missing him. As he saw that even now he could not reach the detective, he uttered a cry of rage, and again and again endeavored to strike him with the dangling chain.

But it was useless. Mr. Barnes was beyond his reach. Finally, with a cry of despair, the Doctor threw himself in a heap upon the floor, now weeping, now laughing, and shrieking madly:

"They say I am a Wizard! Ha! Ha! Ha! A Wizard! I a Wizard, and I cannot kill a man! Such a simple thing, and yet I cannot do it! A Wizard! I a Wizard! Ha! Ha! Ha! Ha! Ha! Ha!"

His Sanatoxine experiment had proven successful. Dr. Emanuel Medjora was a maniac!

THE END.
