“Dressed just as she was on the first night I saw her,” Lucile whispered as the child passed them.

“She’s making for the elevated station this time,” said Florence as they hurried along after her. “That means a long trip and you are tired. Why don’t you let me follow her alone?”

“Why I—”

Lucile cut her speech short to grip her companion’s arm.

“Florence,” she whispered excitedly, “did you hear a footstep behind us?”

“Why, yes, I—”

Florence hesitated. Lucile broke in:

“There was one. I am sure of it, and just now as I looked about there was no one in sight. You don’t think someone could suspect—be shadowing us?”

“Of course not.”
