“Oh yes, you ought. Why not? In this case it is quite right that he should know. I am going to convince him that he is in a very bad way.”

“You think so?” cried Sir John, leaning forward anxiously.

“Yes, sir, a very bad way, though the conceited young rascal is laughing in his sleeve and mentally calling me a pretender.”

“Indeed, no, Doctor Instow,” cried Jack indignantly.

“What? Why you are saying to yourself all the time that you know better than I.”

“I only felt that I was right and you were wrong, doctor,” said the lad frankly.

“Same thing, my boy,” cried the doctor, smiling. “Not the first time two people have been of different opinions, and we shan’t quarrel, Jack. Know one another too well.”

“Yes, yes,” said Sir John impatiently. “But you said you thought he was in a bad way.”

“I said I was sure.”

“Yes, yes; then what is to be done? We must get him out of the bad way.”
