“What do we know of Miss Ward?” he asked, and Roberts stared at him.

“Know of her?” the physician repeated. “She was sent on the case by Central Registry.”

“And what about her antecedents?” questioned Trenholm. “Where did she spring from? Is she a Washingtonian?”

“She said not,” replied Roberts. “She told me that she had trained in New York.”

“And you know nothing more of her than that?”

“Nothing more.”

“You don’t even know that she was not acquainted with Paul before.”

“What!” Roberts’ eyes opened as well as his mouth. “Why—why—they were strangers.”

“Ah, were they?” with quiet emphasis. “Can you prove it?”

Roberts shook his head. “No; but judging from her manner she had never met Paul before.”
