UNDERSHAFT. Sarah, of course. [They shake hands. He goes over to Barbara] Barbara—I am right this time, I hope.

BARBARA. Quite right. [They shake hands].

LADY BRITOMART [resuming command] Sit down, all of you. Sit down, Andrew. [She comes forward and sits on the settle. Cusins also brings his chair forward on her left. Barbara and Stephen resume their seats. Lomax gives his chair to Sarah and goes for another].

UNDERSHAFT. Thank you, my love.

LOMAX [conversationally, as he brings a chair forward between the writing table and the settee, and offers it to Undershaft] Takes you some time to find out exactly where you are, don't it?

UNDERSHAFT [accepting the chair] That is not what embarrasses me, Mr Lomax. My difficulty is that if I play the part of a father, I shall produce the effect of an intrusive stranger; and if I play the part of a discreet stranger, I may appear a callous father.

LADY BRITOMART. There is no need for you to play any part at all, Andrew. You had much better be sincere and natural.

UNDERSHAFT [submissively] Yes, my dear: I daresay that will be best. [Making himself comfortable] Well, here I am. Now what can I do for you all?

LADY BRITOMART. You need not do anything, Andrew. You are one of the family. You can sit with us and enjoy yourself.

Lomax's too long suppressed mirth explodes in agonized neighings.
