dismissed. The lean, frock-coated figure of Mr. Kennedy
arose.

"Doctor Sherman," he called.

Doctor Sherman seemed to experience some difficulty in making his way
up to the witness stand. When he faced about and sat down the
difficulty was explained to the crowd. He was plainly a sick man.
Whispers of sympathy ran about the court-room. Every one knew how he
had sacrificed a friend to his sense of civic duty, and everyone knew
what pain that act must have caused a man with such a high-strung
conscience.

With his hands tightly gripping the arms of his chair, his bright and
hollow eyes fastened upon the prosecutor, Doctor Sherman began in a
low voice to deliver his direct testimony. Katherine listened to him
rather mechanically at first, even with a twinge of sympathy for his
obvious distress.

But though her attention was centred here in the court-room, her brain

Far down in the depths of her mind the question was faintly suggesting

for cross-examination, Katherine walked up before him and looked him
straight in the eyes a full moment without speaking. He could no
longer avoid her gaze. In his eyes she read something that seemed to
her like mortal terror.

"Doctor Sherman," she said slowly, clearly, "is there nothing you
would like to add to your testimony?"

His words were a long time coming. Katherine's life hung suspended
while she waited his answer.

"Nothing," he said.

"There is no fact, no detail, that you may have omitted in your direct
testimony, that you now desire to supply?"

"Nothing."

She took a step nearer, bent on him a yet more searching gaze, and put
into her voice its all of cons
