Prokop smiled as he interrupted. He admired the insight of the Red Envoy.
The masked man knew that the accident had been the work of the Red agents, even though Prokop had not revealed the fact that his men had tampered with the elevator.
“That,” said Prokop, “was one of Prince Zuvor’s safe ways of leaving his house. A man should have died in that crash — somehow, he must have escaped.”
“Who was the man who escaped?” came the Red Envoy’s question.
“Cranston, perhaps,” answered Prokop. “I have not yet called Agent G, to learn if a report has come from Fritz Bloch.”
“Make the call immediately.”
Prokop went to the telephone. He gave a number.
Prokop had an ingenious method of communicating with his agents. At each meeting, an announcement was made of a new telephone number, where one of the agents — usually Agent G — would be stationed. Any messages were phoned by agents to that number.
By calling the number himself, Prokop could learn what the agents were doing, and could leave instructions for them.
To-night, he inquired if Agent K had phoned, Receiving an affirmative reply, Prokop began to take down words that were given him over the telephone, by Agent G. Fritz Bloch had sent a report in code.
