Jack leaned forward and thumped on the door with the butt of his weapon.

“Come out,” he called in a clear, firm voice, “in the name of the United States Navy I call on you to surrender. Your light was seen from the warship, and the station is surrounded.”

A moment’s silence followed. The hearts of the boys beat so strongly it seemed to them the very sound must be heard in that tense stillness. Then the boards of the floor creaked under a light tread, and the door was slowly pulled inward.

“Don’t shoot,” said a voice. “I surrender.”

A slender form appeared in the doorway, hands upraised. Jack shot the rays of his flashlight upward. A Chinese youth in American clothes appeared. He was spectacled.

“Are you alone?” demanded Jack.

“Yes, sir.”

“Armed?”

“Yes, sir.”

“Advance and be searched.”
