Bernardet, alert, with his eyes wide open, studying the faces, searching the eyes, mingled with the crowd, looked at the file of people, scrutinized, one by one, the signatures; Bernardet, in mourning, wearing black gloves, seemed more like an undertaker's assistant than a police spy. Once he found himself directly in front of the open door of the lodge and the table where the leaves lay covered with signatures; when in the half light of the corridor draped with black, where the bier lay, he saw a man of about fifty, pale and very sad looking. He had arrived, in his turn in the line, at the table, where he signed his name. Mme. Moniche, clothed in black, with a white handkerchief in her hand, although she was not weeping, found herself side by side with Bernardet; in fact, their elbows touched. When the man reached the table, coming from the semi-darkness of the passage, and stepped into the light which fell full on him from the window, the portress involuntarily exclaimed, "Ah!" She was evidently much excited, and caught the police officer by the hand and said: "I am afraid!" She spoke in such a low tone that Bernardet divined rather than heard what she meant in that stifled cry. He looked at her from the corner of his eye. He saw that she was ghastly, and again she spoke in a low tone: "He! he whom I saw with M. Rovère before the open safe!" Bernardet gave the man one sweeping glance of the eye. He fairly pierced him through with his sharp look. The unknown, half bent over the table whereon lay the papers, showed a wide forehead, slightly bald, and a pointed beard, a little gray, which almost touched the white paper as he wrote his name. Suddenly the police officer experienced a strange sensation; it seemed to him that this face, the shape of the head, the pointed beard, he had recently seen somewhere, and that this human silhouette recalled to him an image which he had recently studied. The perception of a possibility of a proof gave him a shock. This man who was there made him think suddenly of that phantom discernible in the photographs taken of the retina of the murdered man's eye. "Who is that man?"
