Julien glanced inside the automobile. It was daintily upholstered in white. A pile of cushions lay on the seat, there was a glove upon the floor, the faint fragrance of roses seemed to steal out. Almost he fancied that the woman's face was there, leaning a little towards him, with the curious smile about the lips, the wonderful eyes glowing into his. Then he set his teeth.

"You had better inform your mistress," he said, "that there is some mistake. I have not the honor of the acquaintance of Madame Christophor. You have followed the wrong person."

The man hesitated. He seemed perplexed.

"But, monsieur," he persisted, "madame pointed you out herself. It was only because of a block in the roadway that we were not able to catch you up before. We have, indeed, never lost sight of you."

Julien shook his head. "Pray assure madame," he said, "of my most respectful regrets. I have not the honor of her acquaintance."

He walked on. The two men sat for a moment on the box of the car, watching him. Then they turned around and the car disappeared. Julien jumped into a little carriage and drove back to his hotel. As he passed through into the office, the clerk leaned forward.

"Monsieur is desired upon the telephone," he announced.

Julien frowned.

"Who is it?"

The man shrugged his shoulders and pointed to the booth. Julien hesitated. Then he stepped inside and held the receiver to his ear.
