M. Cognard, fussy and chivalrous, offered her a chair. She seemed to be in a terrible state of mental agitation and on the verge of tears, which, however, with characteristic pride she held resolutely in check.

"I have come, Monsieur le Commissaire," she began in a voice hoarse with emotion, "because my mother—Madame la Comtesse de Romaine—and I are desperately anxious—we don't know—we——"

She was trembling so that she appeared almost unable to speak. M. Cognard, with great kindness and courtesy, poured out a glass of water for her. She drank a little of it, and threw him a grateful look, after which she seemed more tranquil.

"I beg you to compose yourself, Mademoiselle," said the commissaire. "I am entirely at your service."

"It is about my brother, Monsieur le Commissaire," rejoined Mademoiselle more calmly, "Monsieur le Comte Jacques de Romaine. He has disappeared. For three days we have seen and heard nothing of him—and my mother fears—fears——"

Her eyes became dilated with that fear which she dared not put into words. M. Cognard interposed at once, both decisively and sympathetically.

"There is no occasion to fear the worst, Mademoiselle," he said kindly. "Young men often leave home for days without letting their mother and sisters know where they are."

"Ah, but, Monsieur le Commissaire," resumed Mademoiselle with a pathetic break in her voice, "the circumstances in this case are exceptional. My mother is a great invalid, and though my brother leads rather a gay life he is devoted to her and he always would come home of nights. Sometimes," she continued, as a slight flush rose to her pale cheeks, "Mademoiselle Philippa would drive him home in her barouche from the theatre. This she did on Tuesday night, for I heard the carriage draw up at our door. I saw the lights of the lanthorns; I also heard my brother's voice bidding Mademoiselle good night and the barouche driving off again. I was in bed, for it was long past midnight, and I remember just before I fell asleep again thinking how very quietly my dear brother must have come in, for I had not heard the opening and shutting of the front door, nor his step upon the stairs or in his room. Next morning I saw that his bed had not been slept in, and that he had not come into the house at all—as I had imagined—but had driven off again, no doubt, with Mademoiselle Philippa. But we have not seen him since, and——"

"And—h'm—er—have you communicated with Mademoiselle Philippa?" asked the commissary with some hesitation.

"No, Monsieur," replied Mariette de Romaine gravely. "You are the first stranger whom I have consulted. I thought you would advise me what to do."
