Leonid Shvernik leaned back in his chair, shocked.

Paul remained there until at last the other shook his head.

Paul said, in English, "Are you absolutely sure?"

"Yes." Shvernik said. "There are no microphones in here. I absolutely know. Who are you?"

Paul said, "In the movement they call you Georgi, and you're top man in the Leningrad area."

Shvernik's hand came up from under the desk and he pointed a heavy military revolver at his visitor. "Who are you?" he repeated.

Paul ignored the gun. "Someone who knows that you are Georgi," he said "I'm from America. Is there any chance of anybody intruding?"

"Yes, one of my colleagues. Or perhaps a secretary."
