_Bobby, lost to all sense of adult dignity, puts out his tongue at Margaret. Margaret, equally furious, catches his protended countenance a box on the cheek. He hurls himself her. They wrestle._ BOBBY. Cat! I'll teach you. MARGARET. Pig! Beast! [She forces him backwards on the table]. Now where are you? DORA. [calling] Juggins, Juggins. Theyll murder one another. JUGGINS. [throwing open the door, and announcing] Monsieur Duvallet. _Duvallet enters. Sudden cessation of hostilities, and dead silence. The combatants separate by the whole width of the room. Juggins withdraws._ DUVALLET. I fear I derange you. MARGARET. Not at all. Bobby: you really are a beast: Monsieur Duvallet will think I'm always fighting. DUVALLET. Practising jujitsu or the new Iceland wrestling. Admirable, Miss Knox. The athletic young Englishwoman is an example to all Europe. [Indicating Bobby] Your instructor, no doubt. Monsieur-- [he bows]. BOBBY. [bowing awkwardly] How d'y' do? MARGARET. [to Bobby] I'm so sorry, Bobby: I asked Monsieur Duvallet to call for me here; and I forgot to tell you. [Introducing] Monsieur Duvallet: Miss Four hundred and seven. Mr Bobby Gilbey. [Duvallet bows]. I really dont know how to explain our relationships. Bobby and I are like brother and sister. DUVALLET. Perfectly. I noticed it. MARGARET. Bobby and Miss--Miss---- DORA. Delaney, dear. [To Duvallet, bewitchingly] Darling Dora, to real friends. MARGARET. Bobby and Dora are--are--well, not brother and sister. DUVALLET. [with redoubled comprehension] Perfectly. MARGARET. Bobby has spent the last fortnight in prison. You dont mind, do you? DUVALLET. No, naturally. _I_ have spent the last fortnight in prison. _The conversation drops. Margaret renews it with an effort._ MARGARET. Dora has spent the last fortnight in prison. DUVALLET. Quite so. I felicitate Mademoiselle on her enlargement. DORA. _Trop merci_, as they say in Boulogne. No call to be stiff with one another, have we? _Juggins comes in._ JUGGINS. Beg pardon, sir. Mr and Mrs Gilbey are coming up the street. DORA. Let me absquatulate [making for the door]. JUGGINS. If you wish to leave without being seen, you had better step into my pantry and leave afterwards. DORA. Right oh! [She bursts into song] Hide me in the meat safe til the cop goes by. Hum the dear old music as his step draws nigh. [She goes out on tiptoe]. MARGARET. I wont stay here if she has to hide. I'll keep her company in the pantry. [She follows Dora]. BOBBY. Lets all go. We cant have any fun with the Mar here. I say, Juggins: you can give us tea in the pantry, cant you? JUGGINS. Certainly, sir. BOBBY. Right. Say nothing to my mother. You dont mind, Mr. Doovalley, do you? DUVALLET. I shall be charmed. BOBBY. Right you are. Come along. [At the door] Oh, by the way, Juggins, fetch down that concertina from my room, will you?
