Mary could not help laughing; but her eyes were still keen and challenging as she said, "Perhaps you'd better change your doctor again, Mr. Beaumaroy. You haven't found one stupid enough!"

Again Beaumaroy had no defence; his nonplussed air confessed that manoeuvre too. Mary dropped her rallying tone and went on gravely, "Unless I'm treated with confidence and sincerity, I can't continue to attend Mr. Saffron."

Mary scornfully cut short his embarrassed pleadings. "There's a good deal more than rules and etiquette involved. It seems to me that it's a matter of common honesty rather than of rules and etiquette——"

"Yes, but you don't understand——"
