“Can you describe these persons to me so that I may be able to identify them?”

“That is not easy, since one of them I have never seen but once, and the other but once in fifteen years.”

Mr. Sharp looked a little puzzled.

“I can, however, tell you this much. One is a man of about forty, who appears somewhat older. The other, his daughter, is a girl of fourteen, or thereabouts. The former is a little absent in manner, or was formerly so; the little girl, I should judge, is attractive in her personal appearance.”

“When did you last meet them?” inquired the lawyer.

“One evening last week.”

“And where?”

“They were then leaning against the railing on the west side of the Park.”

“Can you tell at what hour?”

“About six.”
