“Put another agent on the case. Immediate results are not necessary, even though they are desirable. This matter of Whitburn is most important.”

Prokop nodded. The Red Envoy made no further statement. That subject was closed. Prokop continued with his report.

“This refers to Prince Zuvor,” he said, with a shrewd gleam in his eyes. “I told you that the prince was dangerous.

“A man has called to see him. The man is a millionaire — his name is Lamont Cranston.” Prokop’s voice became suddenly triumphant.

“This man Cranston,” he added, “carries the sign of the Seventh Star.”

This time Prokop believed that he caught an expression of astonishment upon the Red Envoy’s lips.

“That means plotting,” said Prokop emphatically. “Prince Zuvor is a menace. He will make trouble for our cause. We should make an example of him.”

“You are anxious to dispose of Prince Zuvor?”

“I am,” admitted Prokop. “While he lives, my agents wonder why I do not strike him. Three of our men are detailed to watch him.

“Long vigil without result injures their morale. I have a plan which will surely dispose of him. I ask your permission to use it.”
