He smiled.

"Are we not all trying to throw light on a mysterious occurrence?" he asked.

"Monsieur de Romaine wanted to show my emeralds to his mother," rejoined Mademoiselle, somewhat mollified and not a little shamefaced. "I had promised to be his wife—Madame la Comtesse had approved—she looked upon me as a daughter—I had been up to her house to see her—she expressed a wish to see my emeralds—and so on Tuesday I entrusted them to Monsieur de Romaine—and—and——"

Once more her voice broke and she burst into tears. It was a pitiably silly story, of course—that of the clumsy trap set by a fascinating rogue—the trap into which hundreds of thousands of women have fallen since the world began, and into which as many will fall again so long as human nature does not undergo a radical change.

"And when you drove Monsieur de Romaine home on that Tuesday night," continued the Man in Grey; "he had your emeralds in his possession?"

"Yes," replied Mademoiselle through her tears. "He had them in the inside pocket of his coat. I took leave of him at the Lodge. He waved his hand to me and I drove off. That is the last I have seen of him—the scamp!"

Mademoiselle Philippa was evidently taking it for granted that Jacques de Romaine had stolen her emeralds, and she laughed derisively when M. Cognard suggested that mayhap the unfortunate young man had been waylaid and robbed and afterwards murdered by some malefactor who knew that he had the jewels in his possession.

"Well!" commented the dancer with a shrug of her shoulders, "'tis for you, my good Commissaire, to find either my emeralds for me or the murdered body of Monsieur le Comte de Romaine."

After which parting shot Mademoiselle took her departure, leaving an atmosphere of cosmetics and the lingering echo of the frou-frou of silken skirts.
