town, with Dr. Hendryx away on vacation." "I know." He was already in the hall, reaching for his hat. "Man's work is from sun to sun, but a doctor's work is never done," he misquoted. "I'll drive you." Edith followed him out. "You sit back and relax for another ten minutes...." Two hours later, as they drove homeward, the traffic was light, which was fortunate. More than once Mark, in a frowning abstraction, found himself on the left of the center line and had to pull back into his own lane. He had lost patients before, but never without a feeling of personal defeat. Edith said he put too much of himself into every operation. Perhaps he did. And yet—No, there was every reason why the young man should have lived. Yet, just as Mark Williams had felt that he had been successful, the patient had died. In twenty years of marriage, Edith Williams had learned to read his thoughts at times. Now she put a hand comfortingly on his arm. "These things happen, darling," she said. "You know that. A doctor can only do so much. Some of the job always remains in the hands of Nature. And she does play tricks at times." "Yes, confound it, I know it," her husband growled. "But I resent losing that lad. There was no valid reason for it—unless there was some complication I overlooked." He shook his head, scowling. "I ordered an autopsy but—Yes, I'm going to do that autopsy myself. I'm going to turn back and do it now. I have to know!" He pulled abruptly to the left to swing into a side road and turn. Edith Williams never saw the car that hit them. She heard the frantic blare of a horn and a scream of brakes, and in a frozen instant realized that there had been someone behind them, about to pass. Then the impact came, throwing her forward into the windshield and unconsciousness. Edith Williams opened her eyes. Even before she realized that she was lying on the ground and that the figure bending over her was a State Trooper, she remembered the crash. Her head hurt but there was no confusion in her mind. Automatically, even as she tried to sit up, she accepted the fact that there had been a crash, help had come, and she must have been unconscious for several minutes at least. "Hey, lady, take it easy!" the Trooper protested. "You had a bad bump. You got to lie still until the ambulance gets here.
