Could Mrs.Crawley undertake to say that he would appear?
Mrs.Crawley did undertake either that her husband should appear on the Thursday, or else that she would send over in the early part of the week and declare her inability to ensure his appearance.

In that case it was understood the policeman must come.

Then Mr.Walker had suggested that Mr.Crawley had better employ a lawyer.

Upon this Mrs.Crawley had looked beseechingly up into Mr.Walker's face, and had asked him to undertake the duty.

He was of course obliged to explain that he was already employed on the other side.
