He smiled tenderly and nodded his head.

CHAPTER XXIV. THE CALL DIVINE

The Doctor threw off his coat and took charge of the stricken house. He sent his waiting messenger for a faithful nurse, a mountain woman whom he had trained, and began the fight for Mary's life. The collapse into which she had fallen would require weeks of patient care. There was no immediate danger of death, and while he awaited the arrival of help, he turned into the living-room to examine the body of the slain husband.

The head had fallen backward over the side of the lounge and a pool of blood, still warm and red, lay on the floor in a widening circle beneath it. His quick eye took in its significance at a glance. He sprang forward, ripped the shirt wide open and applied his ear to the breast.

“He's still alive!” he cried excitedly.

He examined the ugly wound in the left side and found that the knife had penetrated the lung. The heart had not been touched. The blow on the neck had not been fatal. The shock of the final stroke had merely choked the wounded man into collapse from the hemorrhage of the left lung. The position into which the body had fallen across the couch had gradually cleared the accumulated blood. There was a chance to save his life.

In ten minutes he had applied stimulants and restored respiration, but the deep wheeze from the stricken lung told only too plainly the dangerous character of the wound. It would be a bitter fight. His enormous vitality might win. The chances were against him.
