An ugly smirk went across his face and he cast a glance at the cellar door.
"You always were too smart for your own good," he said softly. "Knowledge can be dangerous."
"How did you think you could get away with it?" I screamed, only too well aware of his implication. "My God, Carse! Six human heads!"
His jaw hardened and he took a menacing step toward me. Then suddenly he stopped, a queer tragic expression coming over his face. He put his hand to his eyes as if to blot out some horrible memory.
"I know, I know!" he cried hysterically. "Six heads—six human heads! Do you think I planned six heads?"
A shudder went through him and he buried his face in both hands and sobbed like a child.
My personal fear gradually subsided as I watched this remorseful quiescence which had come upon him. I realized that he had passed the emotional climax of his crime, and that he was now suffering that terrible reaction which must haunt and terrify all criminals. I took this advantage to gain control of him, for there was no way of determining when his madness would flare again.
"There is only one course open for me," I told him soberly. "I must turn you over to the police. Things like this must be stopped."
He pulled his hands away from his face and stared at me, his eyes fired with dread. "No, no!" he screamed. "Don't give me away. Please, in the name of God, don't give me away! I am sick, I tell you! I am not responsible!"
A feeling of helpless pity went through me as he sank to his knees in hysterical imploration, but I steeled myself against him. The man was mad and dangerous. He must be stamped out without mercy.
"There are asylums——" I began.
"You cannot!" he cried. "You know what they do in asylums. I know! Please help me. I am not responsible. It is the book—the book."
"What book?"
"Drukker—that diary! Can't you see what it has done to me? It's eaten into my brain until I am mad. It's driven me like a slave until I have no other bidding. It taught me how to do these things. It makes me do them."
I pulled him to his feet and shook him unmercifully. He was crying and retching, a pitiable and horrible sight to look upon.
"You are talking irrationally," I cried. "I am your friend and I want to help you, but my first duty is the public welfare. There are six human heads buried in your cellar. There must be no more."
"No more?" he laughed shrilly and threw up both his hands to indicate the count of ten. "No more, you say? There will be ten more before it stops. Ten more! That's what the book says!"
"You want ten?" I demanded incredulously, struck numb by his callousness. "You want ten more to add to those six? Carse, Carse! They are not cabbages you are counting; they are human heads. Do you think I am a fiend to let this continue? No; it must end—it must end on the gallows."
"He died on the gallows!"
"He? Whom are you talking about? Try to make sense, Carse. I am your friend; trust me."
"I am talking of Emil Drukker—the man who taught me how to do these things. He is responsible for them, not I. He is the one to hang for them. Dig him out of his grave and hang him again!"
