Knox rushes from the room. Mrs Knox looks anxiously and excitedly from the window. Then she throws up the sash and leans out. Margaret Knox comes in, flustered and annoyed. She is a strong, springy girl of eighteen, with large nostrils, an audacious chin, and a gaily resolute manner, even peremptory on occasions like the present, when she is annoyed.

MARGARET. Mother. Mother.

Mrs Knox draws in her head and confronts her daughter.

MRS KNOX. [sternly] Well, miss?

MARGARET. Oh, mother, do go out and stop father making a scene in the street. He rushed at him and said "Youre the man who took away my daughter" loud enough for all the people to hear. Everybody stopped. We shall have a crowd round the house. Do do something to stop him.

Knox returns with a good-looking young marine officer.

MARGARET. Oh, Monsieur Duvallet, I'm so sorry—so ashamed. Mother: this is Monsieur Duvallet, who has been extremely kind to me. Monsieur Duvallet: my mother. [Duvallet bows].

KNOX. A Frenchman! It only needed this.

MARGARET. [much annoyed] Father: do please be commonly civil to a gentleman who has been of the greatest service to me. What will he think of us?

DUVALLET. [debonair] But it's very natural. I understand Mr Knox's feelings perfectly. [He speaks English better than Knox, having learnt it on both sides of the Atlantic].
