That night the evening paper in which the first mention of the mysterious French nobleman had been made contained an article cleverly contrived to give point to the mystery in its commercial aspect. The fact had been observed, the article declared, that the nobleman's promenade began and ended at a prominent clothing establishment on Broadway; and then followed, in the guise of a contribution toward the clearing up of the mystery, an interview with the proprietor of the establishment in question. However, the interview left the mystery just where it found it, for all that the tailor told was that the Marquis had bought several suits of clothes from him; that he had shown himself to be an exceptionally critical person in the matter of his wearing apparel; that he had expressed repeatedly his entire satisfaction with his purchases. In another portion of the paper was a glaring advertisement, in which the clothing man set forth, in an animated fashion, the cheapness and desirability of "The Marquis Suit"--a suit that "might be seen to advantage on the person of the afflicted French nobleman now in our midst who had honored it with his approval, and in whose honor it had been named." Upon reading the newspaper narrative and its advertisement pendant, Jaune groaned aloud. He was oppressed by a horror of discovery, and here, as it seemed to him in his morbidly nervous condition, was a clew to his duplex identity sufficiently obvious to be apparent even to a detective. The Count Siccatif de Courtray, as has been intimated, went so far as to fidget while listening to Mademoiselle Carthame's vivacious description of her encounter with the handsome Marquis. Being regaled during the ensuing evening with a very similar narrative--a materially modified version of the events which had aroused in so lively a manner the passion of jealousy in the breast of Jaune d'Antimoine--the Count ceased merely to fidget and became the prey to a serious anxiety. He determined that the next day, quite unobtrusively, he would observe Mademoiselle Carthame in her relations with this unknown but dangerously fascinating nobleman; and also that he would give some attention to the nobleman himself. This secondary purpose was strengthened the next morning, while the Count was engaged with his coffee and newspaper, by his finding in the "Courrier des Etats-Unis" a translation of the paragraph stating the curious fact that the daily walk of the Marquis began and ended at the Broadway tailor shop.
