“Is this truth, or acting?” thought Scales. “Why does she want me here?”

“I have thought it all out so carefully,” continued Lady Scarlett. “You see he is alarmed at the very idea of a doctor coming near him.”

“And yet you bring me here.”

“Yes; you are his old schoolfellow, and he will welcome you as a friend. The fact of your being a doctor will not trouble him.”

“I see,” said Scales.

“Then, while being constantly in his company, you can watch every change.”

“Nice treacherous plan, eh, Lady Scarlett!” said the doctor, laughing.

“Don’t call it that,” she said pitifully. “It is for his good.”

“Yes, yes; of course—of course. It’s only giving him his powder in jam after all. But, tell me, if I agree to take his case in hand—”

“Which you will?” interrupted Lady Scarlett.
