The cab that he had engaged stood waiting at the door. He put the woman inside. She seemed very weak and helpless. "Drive to the ---- Hotel," Duvall called to the chauffeur, then entered the cab and seated himself at the woman's side. He saw Mr. Baker standing upon the sidewalk, and nodded. Then they drove off. The woman lay, in a state of apparent collapse, in one corner of the cab, her face pale, her eyes closed. Duvall, inspecting her as well as he could in the faint light, began to feel grave doubts as to whether after all he had been successful in his ruse. She seemed so little the type of woman he would have associated with the brutal campaign of terror that had been directed against Miss Morton. She clutched a black leather satchel tightly in one hand. Duvall regarded it with interest. If he was right in his assumption that this was the woman he sought, it seemed highly probable that within that satchel lay evidence that might convict her. At least there would be some clue as to who she was, and that in itself would be valuable. The woman seemed to grow weaker and weaker. Her closed eyes, her slow but regular breathing, indicated that the drug he had given her had begun to take effect. Stealthily Duvall's hand reached toward the small black satchel. With eager fingers he pressed the catch, and as the bag opened, began to draw out its contents. The woman, however, seemed far less helpless than he had supposed. She pulled the satchel toward her, her fingers seeking to close it. Duvall discontinued his efforts at once. It would be time enough, he felt, when they had reached the hotel, and the woman had been safely conducted to a room there. He had made his plans carefully in advance, and arranged matters with the hotel manager. There was nothing to do, now, but wait. Presently the woman, who had been regarding him, unnoticed, from beneath lowered lids, uttered a groan, as though in great pain, and clutched her breast. Duvall turned to her at once, speaking in a soothing voice, and assuming a professional manner. "Is anything wrong, Miss? I had hoped you were feeling better." "No, doctor. I'm not. I feel terrible--terrible." "In what way?" "My--my heart. It is in awful shape. I need some stimulant. The--the medicine you gave me made me feel very ill."
