"Where did you find it?" she asked, in a low tone.
"In the album," he answered. "It was loose between the pages."
She took it gently from his fingers, and crossing the room locked it in her desk.
"I had no idea that it was here," she said. "It is a picture of my eldest sister, or rather my step-sister."

"Your step-sister!" he exclaimed. "I had no idea—shall I meet her this afternoon?"
"No!" she answered, gravely. "What do you say—shall we go out now?"
She took up her racket, but he lingered.
"Please don't think me hopelessly inquisitive, Miss Fitzmaurice," he said, "but I have really a reason for being very interested in the original of that picture. I should like to meet your step-sister."
