He took her nearest and burning hand in both of his.

“There, there. Everything will be all right.”

As her fingers gripped his convulsively, a horrible snarling sound, as from an angry hippopotamus, came from Tony. Carlson disengaged the girl’s hand and faced the giant.

“Tony!” he said commandingly.

“Huh?”

“Help me to fix up this head light of mine. Bend those points out straight—so!”

Carlson had seen some remarkable demonstrations in hypnotism in Zurich, and he had been told by Professor Jung that he had exceptional personal power in that line, if he chose to develop it. He remembered that advice now, and he was trying it on Tony.

The giant hesitated, but at last obeyed the imperative and hypnotic voice of the young doctor. He laid the pistol and flash-light on the table, but just within reach of his hand, and then held out one hand for the electric plug.

“There—twist them out again, right there,” said Carlson in a slow, monotonous voice. As he spoke, his other hand closed over a heavy glass paper weight that lay at the farther end of the table. Tony put the plug on the table and bent his face over it.

Carlson felt that he could soon have Tony completely under his own hypnotic power. But time was too precious to wait for that. The “boss” might return any minute. There was only one thing to do, and Carlson did it.
