He followed the direction of her hand, but saw nothing except scared faces and cringing figures. "What boy, woman?" he retorted. "What do you mean?" "The boy who came after us to the church," she answered. "I saw him a minute ago--there! He was standing behind that man, looking under his arm." Three strides brought the captain of the watch to the place indicated. But there was no boy there--there was no boy to be seen. Moreover, the frightened servants who stood in that part declared that they had seen no boy--that no boy could have been there. The captain, believing that they had had eyes only for Madame de Vidoche, put small faith in their protestations; but the fact remained that the boy was gone, and the searcher returned baffled and perplexed: more than half inclined to think that this might be a ruse on the woman's part, yet at a loss to see what good it could do her. He asked her roughly how old the boy was. "About twelve," she answered, looking nervously over her shoulder. In truth, she began to fancy that the boy was a familiar. Or what could bring him here? How had he entered? And whither had he vanished? "How was he dressed?" the captain asked angrily, waving back the servants, who would have pressed on him in their curiosity. "In black velvet," she answered. "But he had no cap. He was bareheaded. And I noticed that he had black hair and blue eyes." "Are you sure that the boy you saw here was the boy who followed you and spoke to madame in the street?" he urged. "Be careful, woman!" "I am certain of it," she answered feverishly. "I knew him in a moment." "Are you sure that madame did not bring him in with you?" She vowed positively that she had not, and equally positively that the boy could not have followed them in without being seen. In this we know that she was mistaken; but she believed it, and her belief communicated itself to her questioner. He rubbed his head with his hand in extreme perplexity. If the boy were a messenger from the villain whom this wretched woman had been to visit, what could have brought him to the house? Why had he risked himself on the scene of the murder? Unless--unless, indeed, his mission were to learn what happened, and to warn his master! The captain caught that in a moment, and, thrusting the servants on one side, despatched three or four men on the instant to the Rue Touchet, "_Pardieu!_" he exclaimed, wiping his forehead when they were gone, "I was nearly forgetting him. The villain! I will be sworn he tempted her! But now I think I have netted all--madame, the maid, the man, the devil!" He ticked them off on his fingers. "There is only the lad wanting. The odds are they will get him, too, in the Rue Touchet. So far, so good. But it is hateful work," the old soldier continued, with an oath, looking askance at the group which surrounded madame and the doctor. "They will--ugh! it is horrible. It would be a mercy to give her a dose now, and end all."
