"He has seized her—gagged her," I cried in an agony of suspense.

We could now hear everything that was going on in the library. Craig was wildly excited. As for me, I was speechless. Here was the vocaphone we had installed. It had warned us. But what could we do?

I looked blankly at Kennedy. He was equal to the emergency.

He calmly turned a switch.

Then, at the top of his lungs, he shouted, "Help! Help! Police! They are strangling me!"

I looked at him in amazement. What did he think he could do—blocks away?

"It works both ways," he muttered. "Help! Murder! Police!"

We could hear the astounded cursing of the two men. Also, down the hall, now, we could hear footsteps approaching in answer to his call for help—Aunt Josephine, Jennings, Marie, and others, all shouting out that there were cries in the library.

"The deuce! What is it?" muttered a gruff voice.

"The man in armor!" hissed Clutching Hand.
