"My daughter has gone, now," she said. "You may look over the plumbing in the bathroom whenever you are ready."
With a nod Duvall picked up his tools and followed her to the front of the apartment. As they left the kitchen, Mrs. Morton closed the door leading from it to the hall.
"I want you to stay here for the next hour, Sarah," she said, as she left the kitchen. "If anyone rings, I will answer the bell." A moment later she and Duvall were in the library.
The latter pretended to be busy inspecting the connections of the hot water radiator.
"Have you received any more threats?" he asked, in a low voice, without turning his head.
Mrs. Morton took the telegram that Ruth had received a short time before, and placed it in his hand.
"This came half an hour ago," she said, without further comment.
Duvall read it, then thrust it into his pocket.
"Did your daughter see it?" he asked.
"Yes. It had been delivered to her before I could prevent it."
