"You saw them ?" he exclaimed.

"Tell me how." She told him the whole story, how she had come down the staircase, what she had seen, as she leaned over the balustrade, and how Parminter had turned.
"Do you think he saw you ?" asked her father.
Sylvia looked at him closely.

But he seemed really anxious to know.
"I think he saw something," she answered.
