"Why, nonsense, I'm all right," she replied. "One would think you were on the watch for fever patients just for the sake of showing off your discovery! It would be poetic, though, if you could make your final proof and demonstration by curing your own sister!"

Clarendon started violently and guiltily. Had she suspected his wish? Had he muttered anything aloud? He looked at her closely, and saw that she had no inkling of the truth. She smiled up sweetly into his face and patted his hand as he stood by the side of the lounge. Then he took a small oblong leather case from his vest pocket, and taking out a little gold syringe, he began fingering it thoughtfully, pushing the piston speculatively in and out of the empty cylinder.

"I wonder," he began with suave sententiousness, "whether you would really be willing to help science in—something like that way—if the need arose? Whether you would have the devotion to offer yourself to the cause of medicine as a sort of Jephthah's daughter if you knew it meant the absolute perfection and completion of my work?"

Georgina, catching the odd and unmistakable glitter in her brother's eyes, knew at last that her worst fears were true. There was nothing to do now but keep him quiet at all hazards and to pray that Margarita had found James Dalton at his club.

"You look tired, Al dear," she said gently. "Why not take a little morphia and get some of the sleep you need so badly?"

He replied with a kind of crafty deliberation.

"Yes, you're right. I'm worn out, and so are you. Each of us needs a good sleep. Morphine is just the thing—wait till I go and fill the syringe and we'll both take a proper dose."

Still fingering the empty syringe, he walked softly out of the room. Georgina looked about her with the aimlessness of desperation, ears alert for any sign of possible help. She thought she heard Margarita again in the basement kitchen, and rose to ring the bell, in an effort to learn of the fate of her message. The old servant answered her summons at once, and declared she had given the message at the club hours ago. Governor Dalton had been out, but the clerk had promised to deliver the note at the very moment of his arrival.

Margarita waddled below stairs again, but still Clarendon did not reappear. What was he doing? What was he planning? She had heard the outer door slam, so knew he must be at the clinic. Had he forgotten his original intention with the vacillating mind of madness? The suspense grew almost unbearable, and Georgina had to keep her teeth clenched tightly to avoid screaming.
