“How long was he there?”

“A few hours.”

“Where did he go after that?”

“I followed him to his house.”

“Good! Did you make arrangements to watch while you left?”

“Yes. The house is carefully guarded.”

“Go back, then, and keep watching. Observe any one who may enter there. No further instructions.”

“I have been considering what happened last night,” said Prokop. “You acted rashly. Nothing may come of it; but we must be safe.”
