"Herr Freudenberg," he murmured.

"Prince Adolf Rudolf von Falkenberg," she corrected him. "Do you know the story of my married life?"

"I have never heard it," he told her.

"I will spare you the details," she continued. "My husband married me with the sole idea of using my house, my friends, my social position here for the furtherance of his schemes. Under my roof I discovered meetings of spies, spies paid to suborn the different services in this country—the navy, the army, the railway works. When I protested, he laughed at me. He made no secret of his ambitions. He is the sworn and inveterate enemy of your country. His feeling against France is a slight thing in comparison with his hatred of England. For the last ten years he has done nothing but scheme to humiliate her. When I discovered to what purpose my house was being put, I bade him leave it. I bade him choose another hotel, and when he saw that I was in earnest, he obeyed. It is one of the conditions of our separation that he does not cross my threshold. That is why I say, Sir Julien, that you have nothing to fear in accepting the shelter of my roof."

"Madame Christophor," Julien said earnestly, "I am most grateful for your offer. At the same time, I honestly do not believe that I have anything to fear anywhere. Herr Freudenberg has made one attempt upon me and has failed. I do not think that he is likely to risk everything by any open assaults. In these civilized days of the police, the telephone and the law courts, one is not so much at the mercy of a strong man as in the old days. I do not fear Herr Freudenberg."

Madame Christophor shrugged her shoulders.

"My friend," she admitted, "I admire your courage, but listen. You say that one attempt has already been made to silence you. For every letter you write, there will be another made. At each fresh one, these creatures of Herr Freudenberg's will have learned more cunning. In the end they are bound to succeed. Why risk your life? I offer my house as a sanctuary. There is no need for you to pass outside it. You could take the exercise you require in my garden, which is bounded by four of the highest walls in Paris. You can sit in a room apart from the rest of the house, with three locked doors between you and the others. You may write there freely and without fear."

Julien smiled.

"I am afraid it is my stupidity," he said, "but I cannot possibly bring myself to believe in the existence of any danger. I will promise you this, if I may. If any further attempt should be made upon me, any attempt which came in the least near being successful, I will remember your offer. For the present my mind is made up. I shall remain where I am."

She shrugged her shoulders.
