"What good will it do him if you kill yourself? Be sensible. Think what your father would wish you to do."

"Yes, I will," she said. "I'll be good. I'll stay here till you say I may move. Do ask him if he is hurt."

"I know you'll keep your word." Cragg left her, and went nearer, calling in strong tones, "Pattie is safe. Are you hurt?"
