It was three o'clock when the cab drew up at the curb. In spite of the lateness of the hour, there were a good many persons moving in and out of the station. Duvall got out and motioned to Grace and Leary to do the same.
"We will all go in by different doors," he explained, "and meet in the general waiting-room. If the women are not there, Mrs. Duvall will look through the women's room. If you see them, and they make no effort to escape, wait for me to join you. If they do try to get away, detain them until I come."
It was Duvall himself, however, who first caught sight of the objects of their pursuit. They sat, both apparently asleep, on a bench in one corner of the main waiting room. The detective was not certain of their identity, heavily veiled as they were, until he had gone quite close up to them. Then he saw that they were Miss Ford and the woman who had escaped from him while in the cab the night before.
He leaned over and tapped the Ford girl on the shoulder.
"Wake up, Miss Ford," he exclaimed.
The girl shivered, then struggled to her feet. Her companion appeared to be too dazed to move, although she opened her eyes and stared at him with a vague and terrified face.
"Will you come with me quietly," he said, "or shall I call a policeman and have you put under arrest for the attack upon my wife?" He addressed himself more particularly to the woman who was sitting.
She now rose and made a movement as though to attempt to escape. Duvall grasped her by the arm.
"It will be quite useless to attempt it, Miss Norman," he said. "I have help close at hand in case it is needed." He glanced toward Grace and Leary, who were now approaching. "I do not wish to use any violence, of course, but you and your friend are going back to the apartment on Ninety-sixth Street with me."
His voice, his manner, made it apparent to the two women that escape was hopeless. They seemed suddenly to realize it, to give up further ideas of resistance.
