She touched a bell which stood on the table by her side. Almost immediately a tall, pale-faced man in dark clothes appeared, followed by Jean, the butler.

"My dear Prince," she said to her husband, "I do assure you that you need have no special anxiety. Let me present to you Monsieur Bourgan of the French Detective Service. Monsieur Bourgan—the Prince von Falkenberg—Sir Julien Portel!"

Monsieur Bourgan saluted. The two men looked at him,—as yet they scarcely understood.

"I suppose," Madame Christophor continued, "that I am a somewhat nervous woman, but you see I can always plead the privilege of my sex. I was delighted to have Sir Julien here with me, but in a sense it was a responsibility. It occurred to me then to send a message to the Minister of the Police, who happens to be a great friend of mine, and at his suggestion Monsieur Bourgan here, who is, as I have no doubt you both well know, very distinguished in the Service, has taken up his residence in my house. He has occupied, as a matter of fact, the next room to Sir Julien's. Forgive me," she added, smiling at them all, "if I kept this little matter secret, but I know that men hate a fuss. I propose, dear Prince," she added, turning to her husband, "that Monsieur Bourgan accompanies you to your rooms. You need not fear then any molestation."

There was an absolute silence. It was broken at last by the Prince von
Falkenberg.

"I must confess," he said slowly, "that I do not altogether understand."

Madame Christophor faced him with a faint smile upon her lips. The smile itself told him all that he desired to know.

"But, my dear Prince," she declared, "it is my anxiety for your safety which induces me to propose this. Only a few minutes ago you were telling me that you feared that you had become an extremely unpopular person in Paris, and that the very streets were not safe for you. Under the circumstances, one can scarcely wonder at it! The French Government, however, is above all small feelings. A private citizen in Paris, even though he be an enemy of France, is a person to be respected. The protection of the detective force of Paris is at your service. Monsieur Bourgan, you will do me the great favor of conducting my husband to his rooms. Afterwards you will return here to continue your watch over Sir Julien."

"I am entirely at your command, madame," Monsieur Bourgan replied.

Falkenberg hesitated for one single moment. He seemed to be measuring the distance between Julien and himself. Under the pretense of picking up a match, Monsieur Bourgan was almost between them. Falkenberg laughed softly, then most graciously he made his adieux.
