"How could I play the queen when I knew that the ace was against me?" The phrases came in little spurts falling back into the dull murmur of conversation. And then suddenly he heard the creaking of a door and a step in the hall, and knew with a tingling mixture of impatience and horror that the crisis of his life was at hand.

Dr. Horace Selby was a large, portly man with an imposing presence. His nose and chin were bold and pronounced, yet his features were puffy, a combination which would blend more freely with the wig and cravat of the early Georges than with the close-cropped hair and black frock-coat of the end of the nineteenth century. He was clean shaven, for his mouth was too good to cover – large, flexible, and sensitive, with a kindly human softening at either corner which with his brown sympathetic eyes had drawn out many a shame-struck sinner's secret. Two masterful little bushy side-whiskers bristled out from under his ears spindling away upwards to merge in the thick curves of his brindled hair. To his patients there was something reassuring in the mere bulk and dignity of the man. A high and easy bearing in medicine as in war bears with it a hint of victories in the past, and a promise of others to come. Dr. Horace Selby's face was a consolation, and so too were the large, white, soothing hands, one of which he held out to his visitor.

"I am sorry to have kept you waiting. It is a conflict of duties, you perceive – a host's to his guests and an adviser's to his patient. But now I am entirely at your disposal, Sir Francis. But dear me, you are very cold."

"Yes, I am cold."

"And you are trembling all over. Tut, tut, this will never do! This miserable night has chilled you. Perhaps some little stimulant – "

"No, thank you. I would really rather not. And it is not the night which has chilled me. I am frightened, doctor."

The doctor half-turned in his chair, and he patted the arch of the young man's knee, as he might the neck of a restless horse.

"What then?" he asked, looking over his shoulder at the pale face with the startled eyes.

Twice the young man parted his lips. Then he stooped with a sudden gesture, and turning up the right leg of his trousers he pulled down his sock and thrust forward his shin. The doctor made a clicking noise with his tongue as he glanced at it.

"Both legs?"

"No, only one."

"Suddenly?"

"This morning."

"Hum."

The doctor pouted his lips, and drew his finger and thumb down the line of his chin. "Can you account for it?" he asked briskly.

"No."

A trace of sternness came into the large brown eyes.

"I need not point out to you that unless the most absolute frankness – "

The patient sprang from his chair. "So help me God!" he cried, "I have nothing in my life with which to reproach myself. Do you think that I would be such a fool as to come here and tell you lies. Once for all, I have nothing to regret." He was a pitiful, half-tragic and half-grotesque figure, as he stood with one trouser leg rolled to the knee, and that ever present horror still lurking in his eyes. A burst of merriment came from the card-players in the next room, and the two looked at each other in silence.

"Sit down," said the doctor abruptly, "your assurance is quite sufficient." He stooped and ran his finger down the line of the young man's shin, raising it at one point. "Hum, serpiginous," he murmured, shaking his head. "Any other symptoms?"

"My eyes have been a little weak."

"Let me see your teeth." He glanced at them, and again made the gentle, clicking sound of sympathy and disapprobation.
