Surveyed in cool retrospect, her momentary thought-panic in Hyde Park appeared a mere firework of the literary imagination. Nevertheless, ever since Sunday, when she had tried, over dinner, to let him inkle her knowledge, to warn him, she had been reproaching herself about Ronnie. Other mothers--her own sister Clementina among them--did not apparently find it at all difficult to discuss sex matters with their sons. Yet she, the celebrated psychologist, had found it impossible. "If only I could have been open with him," she thought, "if only I could have said: 'I'm afraid that you've fallen in love with that charming Mrs. Brunton. You won't let it go too far--will you? Women's heads are so easily turned.'" She would not, of course, have said more than that. Ronnie was so sensible, so straight and clean, that he would have needed no further warning. Ronnie--her Ronnie--did not in the least resemble the heroes of her novels, the passionate men with cleft chins who occasionally counted the world well lost for love. Ronnie was the very spit of his father, the Oxford don. Still even dons were human. And Ronnie, unwarned, might have lost his head. As for the woman--women, according to Julia Cavendish, could always fall prey to the sentimental impulse. If only a man were sufficiently ardent the entire sex yielded to him. Why should this Mrs. Brunton be the exception? Ronnie--her Ronnie--must be terribly attractive. Therefore---- And quite suddenly, Julia panicked again. Her literary imagination saw the worst; Aliette in Ronnie's arms, Ronnie in the divorce court. Her heart went cold at the imaginary prospect. The mother, the religious woman, and the Victorian in her were alike appalled. Jealousy spread a yellow jaundice film over her intellect. Seen through that film, the "charming Mrs. Brunton" became a harpy, an over-dressed, over-scented, over-manicured harpy, her unguented claws sharp for an innocent boy. Whereupon Julia Cavendish--turning, as most literary people in a crisis, to her pen--began the composition of a letter which should convey, tactfully, of course, the picture of the harpy to the mind of the boy. But the letter, completed, read so much more like a piece of fiction than a statement of fact, that she tore it up; and contented herself with the usual note ordering him to dinner on Saturday. 3 The note itself contained nothing to alarm Ronnie; and yet, dressing to obey its commands in his severe mannish bedroom, he felt nervous about the coming interview. For five days now he had been on edge; sleepless, unable to concentrate thought.
