"And pray how did Dora happen on your brother? It is a vera singular coincidence, and I am no believer in coincidences. If the truth were known, they have all o' them been carefully planned, and weel arranged."

"She did nothing o' the kind."

"You lie, Robert Campbell. I was his mother."
"You ought to be proud of it."
