He seemed highly nervous, and at the same time extremely puzzled. Receipt of that unique and beautiful brooch was, I saw, some sign, but of its real significance I remained in entire ignorance.

That it had a serious meaning I quickly realized, for within half an hour the Crown-Prince and myself were in the train on our two-hundred-mile journey back to Berlin.

On arrival His Imperial Highness drove straight to the Berlin Schloss, and there had a long interview with the Emperor. At last I was called into the familiar pale-green room, the Kaiser's private cabinet, and at once saw that something untoward had occurred.

The Emperor's face was dark and thoughtful. Yet another of the black plots of the Hohenzollerns was in process of being carried out! Of that I felt only too confident. The Crown-Prince, in his badly-creased uniform, betraying a long journey—so unlike his usual spick-and-span appearance—stood nervously by as the Kaiser threw himself into his writing-chair with a deep grunt and distinctly evil grace.

"I suppose it must be done," he growled viciously to his son. "Did I not foresee that the girl would constitute a serious menace? When she was in Germany she might easily have been arrested upon some charge and her mouth closed. Bah! our political police service grows worse and worse. We will have it entirely reorganized. The Director, Laubach, is far too sentimental, far too chicken-hearted."

As he spoke he took up his pen and commenced to write rapidly, drawing a deep breath as his quill scratched upon the paper.

"You realize," he exclaimed angrily to his son, taking no notice of my presence there, because I was part and parcel of the great machinery of the Court, "you realize what this order means?" he added, as he appended his signature. "It is a blow struck against our cause—struck by a mere slip of a girl. Think, if the truth came out! Why, all our propaganda in the United States and Britain would be nullified in a single day, and the 'good relations' we are now extending on every hand throughout the world in order to mislead our enemies would be exposed in all their true meaning. We cannot afford that. It would be far cheaper to pay twenty million marks—the annual cost of the whole propaganda in America—than to allow the truth to be known."

Suddenly the Crown-Prince's face brightened, as though he had had some sudden inspiration.

"The truth will not be known, I promise you," he said, with a strange, evil grin. I knew that expression. It meant that he had devised some fresh and devilish plan. "The girl is defiant to-day, but she will not remain so long. I will take your order, but I may not have occasion to put it in force."

"Ah! You have perhaps devised something—eh? I hope so," said the Emperor. "You are usually ingenious in a crisis. Good! Here is the order; act just as you think fit."
