“I questioned him regarding that,” replied Agent C. “I was watching from the shore, two nights ago. I saw a torpedo fall in the lake.
“Crawford came out in the boat, two hours later, and removed it. But it would have been no good to us. The secret lies in the projecting mechanism; not in the torpedo.”
“Has our agent examined the mechanism?”
“Yes; but there are unknown attachments which the professor applies, alone. He possesses knowledge which none of the others have received.”
“Then how will we know if the correct plans are found?”
“Our agent knows sufficient to identify them if he sees them. He needs only a few clews in the form of diagrams. But those are essential.”
Prokop made a motion as if to dismiss the agent; then he called the man back.
“The new man, Vincent,” he said. “Instruct Agent E to remove him as soon as possible.”
“I shall do so.”
“Let Crawford remain — for a while. He is evidently of importance in the work. We have managed to move along without interference from him. But as for Vincent — there is only one order. Strike!”
