"In the Stone Age no man dared to come between man and woman," said Denton.

The hypnotist thought again.

"What are you going to do?" he asked.

"While you were insensible I found the girl's address on your tablets. I did not know it before. I telephoned. She will be here soon. Then—"

"She will bring her chaperone."

"That is all right."

"But what—? I don't see. What do you mean to do?"

"I looked about for a weapon also. It is an astonishing thing how few weapons there are nowadays. If you consider that in the Stone Age men owned scarcely anything but weapons. I hit at last upon this lamp. I have wrenched off the wires and things, and I hold it so." He extended it over the hypnotist's shoulders. "With that I can quite easily smash your skull. I will—unless you do as I tell you."

"Violence is no remedy," said the hypnotist, quoting from the "Modern Man's Book of Moral Maxims."

"It's an undesirable disease," said Denton.
