"What are you thinking of doing?" asked Aunt Josephine keenly.
"I'm going to put in a vocaphone," he returned unwrapping it.
"What's that?" she asked.
"A loud speaking telephone—connected with my laboratory," he explained, repeating what he had already told me, while she listened almost awe-struck at the latest scientific wonder.
He was looking about, trying to figure out just where it could be placed to best advantage, when he approached the suit of armor.
"I see you have brought it back and had it repaired," he remarked to Aunt Josephine. Suddenly his face lighted up. "Ah—an idea!" he exclaimed. "No one will ever think to look INSIDE that."
It was indeed an inspiration. Kennedy worked quickly now, placing the little box inside the breast plate of the ancient armourer with the top of the instrument projecting right up into the helmet. It was a strange combination—the medieval and the ultra-modern.
"Now, Mrs. Dodge," he said finally, as he had completed installing the thing and hiding the wire under carpets and rugs until it ran out to the connection which he made with the telephone, "don't breathe a word of it—to anyone. We don't know who to trust or suspect."
"I shall not," she answered, by this time thoroughly educated in the value of silence.
Kennedy looked at his watch.
