"So much the better. I shall want you to assist me. I read in the Medical Gazette, the other day, an account of a very interesting operation of yours. I felt proud to number you among my pupils. It was a remarkable case—a rare case. I must certainly have you with me in this one."
"I shall be delighted, sir," returned Miller, "if it is agreeable to all concerned."
Several hours were passed in pleasant conversation while the train sped rapidly southward. They were already far down in Virginia, and had stopped at a station beyond Richmond, when the conductor entered the car.
"All passengers," he announced, "will please transfer to the day coaches ahead. The sleeper has a hot box, and must be switched off here."
Dr. Burns and Miller obeyed the order, the former leading the way into the coach immediately in front of the sleeping-car.
"Let's sit here, Miller," he said, having selected a seat near the rear of the car and deposited his suitcase in a rack. "It's on the shady side."
Miller stood a moment hesitatingly, but finally took the seat indicated, and a few minutes later the journey was again resumed.
When the train conductor made his round after leaving the station, he paused at the seat occupied by the two doctors, glanced interrogatively at Miller, and then spoke to Dr. Burns, who sat in the end of the seat nearest the aisle.
"This man is with you?" he asked, indicating Miller with a slight side movement of his head, and a keen glance in his direction.
"Certainly," replied Dr. Burns curtly, and with some surprise. "Don't you see that he is?"
