"Her manners, Sir, and her behaviour, and sometimes a look she has in her eyes; but her conversation, principally."
"Have you had any experience of mad people?"
"Yes, Sir. Father once took charge of a niece of his that was mad."
"What form did her madness take?"
"She was very cunning. Her mind was full of crazy thoughts; but she seemed to know that if she spoke them she would be thought mad. But she couldn't always hide them. And she was very artful. She would steal things and hide them so that nobody could find them. She was taken worse after she had been with us a year, and we had to send her to an asylum over at Barnstock, where she died raving."
"You would be more likely, after such an experience, to know madness when you saw it than I?"
"Yes, Sir."
"And do you seriously and truly think Mrs. Thorburn mad?"
"You ask me, Sir—it's painful to say—but I would swear there is madness in her."
