n'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."

Her words surprised Duvall. He had given her a simple drug, the effect
of which should have been to make her drowsy, to quiet her nerves. That
she had not taken it, he of course did not know. His greatest fear had
been that she would refuse to enter the cab with him. Now that she had
done so, he was prepared to use even force, if necessary, to retain her
in his custody
