A F T E R T H E P E R F O R M A N C E George: Well, how did you enjoy the play, Margaret? Margaret: Oh, enormously! I thought the production was really brilliant, and so was the acting.George: If Nickolson hadn't been ill, it would have been even better. They say he's wonderful in the part of the inspector.Margaret: But his understudy was very good too, particularly in the last act. Of course, the plot was rather absurd...George: It usually is in detective plays .Margaret: Take the wife, for instance. She didn't behave like a normal human being at all. If she had only owned up to her husband, he would have settled the whole business in no time.George: But she was supposed to be a dumb blonde. And if she hadn't been, there wouldn't have been a plot, would there?Margaret: And you know, there wouldn't have been a second murder if the inspector hadn't told everybody about his plans.George: But then the audience would have had to go home at the end of the first act.Margaret: Then take that episode with the revolver. If he had had any sense, he would have told his wife about the gun instead of trying to hide it.George: It's a pity you didn't write the play, Margaret. If you had, you would have made a much better job of it. The wife would have confessed to herhusband, he would have told the inspector, and there wouldn't have beenany corpses. A much better play altogether. Not a thriller, of course...
