The agent bowed, and left the room. Prokop suddenly opened the door that led to the meeting place.
“Ah!” he exclaimed. “What are you doing here, listening by the door?”
A small, robed figure entered. The last agent removed the disguise, and Arlette DeLand faced Prokop.
“Agent R,” said Prokop sternly, “I had you remain because I suspected that you were hearing the instructions which I gave to others.
“You have been failing in your work for the cause. Now you may tell me what you heard — while you were listening there.”
“You are seeking an excuse,” replied the girl. “You kept me until the others had gone so you could resume your talk — which was interrupted the other night. Unless you have instructions for me, I shall go.”
Prokop caught the girl’s wrist as she stepped toward the door.
“You shall remain,” he hissed.
“Do not forget the Red Envoy,” returned Arlette. “Remember: he is your master.”
Prokop released her for a moment; then he suddenly leaped past her, and blocked the way to the door.
