"And Della can tell the truth to the sheriff whenever she gets ready!" The other watcher was Della Wharton.

She had seen the sheriff leave town, to ride southward, and she had divined what his errand meant.

And she had sat in a chair near a window for many hours, peering into the darkness for Moreton's return with his prisoner.

And when she saw them coming she smiled as she had smiled when she had entered the room after taking leave of Warden.
Della knew Warden better than Warden knew himself; and on the night when he had asked her to sign the statement charging Lawler with murder, she was convinced that Warden intended to use the statement.

He had told her that he merely intended to hold it as a threat over Lawler's head, to dissuade him from succeeding politically; and she had permitted Warden to think that she believed him.
