"Is this you, Mrs. Duvall?" the cabman asked.
"Yes. What have you discovered?"
"The lady got into her cab a little while after you left me, and drove away. I followed, as you told me to do. She drove to an apartment on 96th Street, left her taxicab, and entered. The cab drove away. I'm waiting across the street, in a drug store. The apartment is on the corner, 96th Street and Columbus Avenue. Shall I stay here?"
"Yes. Wait until I come." Grace left the booth, and hunting up the clerk, told him that she was obliged to go out at once.
"Mrs. Morton should be back very soon," she said. "One of the maids is sitting with Miss Ruth. Hadn't you better stay with her, as well?"
The clerk nodded, then saw the doctor coming through the lobby.
"Here's Dr. Benson," he said. "I'll send him up. The young lady will be quite safe, until her mother comes."
Grace bowed to the doctor, then hurried out of the hotel, and jumping into a taxi, ordered the driver to take her to Columbus Avenue and 96th Street. She felt overjoyed, to know that the woman Duvall had been seeking had at last been run to earth. She should, Grace determined, not escape a second time.
At 96th Street, she found Leary, impatiently waiting for her in the doorway of the corner drug store from which he had telephoned. He saw her as soon as she left the cab and, tipping his cap, came forward and joined her.
"She's in there yet, Miss," he whispered, jerking his thumb toward the building on the opposite corner.
