"I remember the case," Katharine continued,—"appendicitis, followed by pneumonia, and complicated by angina pectoris."
"You have it precisely."
Katharine's eyes were full of perplexity.
"But the man is in very poor circumstances," she remarked. "How on earth can he afford a trip like this? He was on the free list at the hospital."
The doctor frowned.
"That is not my business," he said. "My fees are paid, and the steamer tickets appear to be in order. He probably has wealthy friends."
Katharine looked down once more at the sleeping man. His face was insignificant, his expression peevish, his features without the animation of any high purpose.
"I really cannot understand," she murmured, "how he became a friend—a friend—"
"A friend of whom?" the doctor enquired.
Katharine reflected and shook her head.
