"You know of a way?" he questioned incredulously.

"Yes, sir. At least if the information Tom and I have on the subject is correct."

Jack nodded.

"I know all that," he said.

"And yet you are prepared to get it back?"

"I said I thought there was a possibility," was Jack's quiet reply.

"And what may that be?"

"Did you ever hear of Z.2.X., doctor?" was the entirely unexpected question.
