The physician glanced at him, and suppressed a professional shrug of the shoulders.

‘We shall see what happens at noon,’ he answered, but the tone of his voice was sceptical.

To tell the truth he believed that there was no longer any hope whatever, and so far as any such chance was concerned he would almost have risked going home at once. Nevertheless he determined to stay to the very last, partly because his reputation was at stake, partly out of curiosity to watch Rex at the supreme moment. He suspected that the latter was in some way profoundly interested in the question of Greif’s life, though he found it quite impossible to make sure whether his anxiety proceeded from affection or from some more selfish motive. For the present, however, he left Rex to himself and went to his own room to rest an hour or two.

The time passed very slowly. Rex’s nerves were as firm as the rest of his singularly well-knit constitution, and he was never weary of fulfilling the mechanical duties of a nurse, which he had refused to relinquish, during twelve hours at least of each day, though he was obliged to give his place to an assistant during the remainder of the time.

In order not to be idle as he sat beside the bed, Rex drew figures and made calculations in his pocket-book. He seemed to derive considerable satisfaction from his occupation, for he looked more hopefully at Greif each time he raised his head, though the latter’s condition showed no apparent change. His consolation was in reality only transitory, for when the clock at last struck twelve and he laid his work definitely aside, it seemed to him that he had been dreaming and that the case was more desperate than ever. The physician returned and stood beside him, but he looked at Rex more often than at Greif. At last he laid his hand upon the younger man’s arm and led him away from the bedside, towards the open window.

‘Herr Rex, I would say a word to you. I firmly believe that your cousin will die in a few minutes.’ He spoke in a whisper, and Rex bent his head, for he thought his companion was right.

‘I have a theory,’ continued the doctor, ‘that people who are dying are far more conscious of what passes around them than is commonly supposed. It may be true or it may not. Let us at all events be careful of what we say to each other.’

Rex nodded gravely, and they returned to the side of the dying man. It was just mid-day, and Greif was lying on his back, with his eyes open. The physician bent down and laid his ear to the heart. When he raised his head again, he looked about the room, somewhat nervously avoiding Rex’s eyes. All at once his attention was arrested by the sound of running feet outside, and he glanced quickly at his companion, who had also heard the noise.

It was the supreme moment, for Greif’s consciousness had returned. As often happens at the moment of death a violent physical struggle began. The light returned to his eyes, and the strength to his limbs. He raised himself upon his hands, and sat up, while the doctor supported him with one arm, and with a quick movement put brandy to his lips. It was the work of an instant, and it all happened while Rex was crossing the room. Suddenly, as the doctor watched him, his eyes fixed themselves. In the next instant, he thought, their light would break; and the body he supported would collapse and fall back for ever. It was the last gasp. Then a ringing voice broke the silence, just as Rex had his hand upon the latch. ‘I will, I tell you—he is mine!’

The door was flung wide open, and a woman entered the room. Rex had a strange impression of golden hair and gleaming eyes passing him like a flash, like the leap of a lioness springing to defend her young.
