"Wait!" Douglas strode rapidly to the door which led to the other rooms of the building. After glancing to right and left, with an explanatory "Walls sometimes have ears, you know!" he locked the door carefully again, came back, and said:

"Talk in a whisper! How about Hill 333?"

"Tanks massed there," Lance said slowly. "Yeh, I saw that, all right. They must be intending an attack on that sector. But—but—Praed—"

"What happened?"

Lance told him of the scrap, how Praed's plane had apparently rubbed wings with a Slav and then tumbled down, out of control. He concluded: "I figured that Praed was all right, that he'd proved himself, that he wasn't a spy, as we'd thought. But the next moment I saw him in the Slav plane that had bagged his!"

His wondering eyes sought the colonel's lean face. Lance expected to see it express amazement, incredulity. It didn't, though. He laughed!


hile Lance gaped, the older man went to the delicate machinery of the radiophone in one corner of the trim office. He clasped the earphones over his head, and spoke into the mike: "Headquarters, Air Force, Washington, Douglas, Base 5, speaking."

A tense moment passed while his radio call was put through. Presently a green light flashed on the board. Douglas said swiftly: "Headquarters? Base 5, Colonel Douglas. Tanks massed around Hill 333; enemy evidently contemplates full attack on corresponding sector of our line. They know a scout of ours observed it, however; perhaps that will induce them to change their plans. This next is extremely important: The first step of the Torpedo Plan has been successful!"
