As he finished speaking the Admiral politely stepped away to give me opportunity for a farewell word with Marguerite. Grauble followed him and, as he passed me, he gave me a look of gloating triumph and then opened the door of his cabin, which the Admiral entered. "I am going with you," whispered Marguerite. "Grauble understands." There was the sound of a scuffle and a strangled oath. Grauble's head appeared at the cabin door. "Here, Armstadt; be quick, and keep him quiet." I plunged into the cabin and saw von Kufner crumpled against the bunk; his hands were manacled behind him and his mouth stuffed with a cloth. With an exulting joy I threw myself upon the man as he struggled to rise. I easily held him down, and whipping out my own kerchief I bound it tightly across his mouth to more effectively gag him. Then rolling him over I planted my knee on his back while I ripped a sheet from the bunk and bound his feet. From without I heard Grauble's voice in command: "Close the hatch." Then I felt the vessel quiver with machinery in motion and I knew that we were moving along the tunnel toward the sea. Grauble appeared again in the door of the cabin. "The mate understands," he said, "and the crew will obey. I told them that the Admiral was going out with us to inspect the lock. But the presence of a woman aboard will puzzle them. I have placed the Princess in the mate's cabin so no one can molest her. We have other things to keep us occupied." With Grauble's help I now bound von Kufner to the staunch metal leg of the bunk and we left him alone in the narrow room to ponder on the meaning of what he had heard. Outside Grauble led me over to the instrument board where the mate was stationed. "Any unusual message?" asked Grauble. "None," said the mate. "I think we will go through without interruption at least until we reach the lock; if anything is suspicioned we will be held up there for examination." "Do you think the guards at the dock suspected anything?" questioned Grauble. "It is not likely," replied the mate. "They saw him come aboard, but he spoke to none of them. They will presume he is going out to the lock. The presence of a woman will puzzle them; but, as she was with the Admiral, they will not dare interfere or even report the fact." "Then what do you think we have to fear?" asked Grauble. "Only the chance that the Admiral's absence may be noted at his office and inquiry be made." "Of that the Princess could tell us something," said Grauble. "We will talk with her." Grauble now led me to the mate's snug cabin, where we found Marguerite seated on the bunk, looking very pale and anxious. "Everything is going nicely, so far," the Captain assured her. "We have only one thing to fear, and that is that inquiry from the Administration Office for the Admiral may be addressed to the Commander of the Lock." "But how will they know that he is with us?" asked Marguerite. "Will the guards report it?"
