Rather than remain longer in Berlin I would take any chance and risk any danger if only Marguerite were not to be left behind. And yet she must be left behind, for such a thing as getting a woman aboard a submarine or even to the submarine docks had never been heard of. I thought of all the usual tricks of disguising her as a man, of smuggling her as a stowaway amidst the cargo, but Grauble's insistence upon the impossibility of such plans had made it all too clear that any such wild attempt would lead to the undoing of us all. If escape were possible with Marguerite--! But cold reason said that escape was improbable enough for me alone. For a woman of the House of Hohenzollern the prison of Berlin had walls of granite and locks of steel. The time of departure drew nearer. I had already been passed down by the stealthy guards and through the numerous locked and barred gates to the subterranean docks where Grauble's vessel, the _Eitel 3_, rested on the heavy trucks that would bear her away through the tunnel to the pneumatic lock that would float her into the passage that led to the open sea. My supplies and apparatus were stored on board and the crew were making ready to be off. But three hours were left until the time of our departure and these hours I had set aside for my final leave-taking of Marguerite. I hastened back through the guarded gates to the elevator and was quickly lifted to the Royal Level where Marguerite was to be waiting for me. With fast beating and rebellious heart I rang the bell of the Countess' apartment. I could scarcely believe I heard aright when the servant informed me that the Princess Marguerite had gone out. I demanded to see the Countess and was ushered into the reception-room and suffered unbearably during the few minutes till she appeared. To my excited question she replied with a teasing smile that Marguerite had gone out a half hour before with Admiral von Kufner. "I warned you," said the Countess as she saw the tortured expression of my face, "but you would not believe me, when I told you the Admiral would prove a dangerous man." "But it is impossible," I cried. "I am leaving for the Arctic mines. I have only a couple of hours; surely you are hiding something. Did you see her go? Did she leave no word? Do you know where they have gone or when they will return?"
