"Ruby"—the voice was almost stern, and now it was more like the voice that Isaacson knew—"Ruby, I'm getting worse. To-day I feel that I'm going to die."

"Let me telegraph for Doctor Hartley. At dawn to-morrow I shall send the boat to Edfou—"

"If only Isaacson were here!"

There was a silence. Then Mrs. Armine said:

"What could Doctor Isaacson do more than has been done?"

"He's a wonderful man. He sees what others don't see. I feel that he might find out what's the matter."

"Find out! But, Nigel, we know it's the sun. You yourself—"

"Yes, yes!"
