"What do you mean, Robert?" asked his sister, lifting her eyes in surprise.
"Just what I say. I want you to be Mrs. Chipman."
"But why should I give up my name?"
"Do you remember what I told you yesterday—about the man who was on your track?"
"You didn't say it was a man."
"Well, I say so now."
"Well, Robert?"
"He will find it harder to trace you if you change your name."
"If you think it right, Robert, I will be guided by your advice."
