"Yes, we'll go," she answered. "I'll write an acceptance and send it by hand."

I was so enchanted at this that I dashed up to my room and began shortening the new dress. I had mentioned it vaguely to Di, but it was the one part of my story in which she took no interest. I saw how the keenness died out of her beautiful sea-blue eyes, and how her soul retired comfortably behind them, to think of something else, just as you see people walk away from windows through which they've been looking out, leaving them emptily blank. As she didn't care what little Peggy wore, little Peggy decided to give her a surprise at the last moment. Nothing much was said about the Embassy ball by Father or Di before me, on that day or the next, so I, too, kept my own counsel. I was afraid if I gabbled as I longed to do, Father might take it into his head that the child had better stop at home. All I heard was a little talk about the time to start, and whether a taxi should be ordered or a coupé. I thought there would be rather a squash in a coupé with Father, Diana, and me folded together in a sort of living sandwich; but I was so small, I could perhaps manage not to slide off the little flap seat with its back to the horses.

It was a coupé they finally decided on, and it was ordered for a quarter to ten. We had a short and early dinner, and as I did Diana's hair, it seemed to me that I had never seen her look prettier. I wondered whether Captain March would admire her very much, and I hoped for his own sake—I almost believed it was for his own sake!—that he wouldn't fall in love. As I thought this, I looked with a new kind of criticism at Di, to judge whether he were likely to be one of her victims.

Heaps of men had fallen in love with Di since I began to be old enough to notice such things. They had never been the right sort of men, from her point of view, for none of the lot had had a penny to bless himself with, or even a title worth the taking. But all of them had been worth flirting with; and after they had been dropped with more or less of a dull thud, I'm afraid some of them had suffered. I didn't wish Captain March to suffer, yet I couldn't help thinking that if I were a man I might be as silly as the rest and go down before Di.

She was then—and she is now—the most lovable looking thing that can be imagined. She doesn't appear to be cool and calculating, but warm-hearted and gentle and soft, far more so than most of the girls one meets, especially in London, where I think they have the air of being rather hard: ready to sacrifice everything and everybody for the sake of what they want to get or do.

If you were going to paint a picture of Ireland, typified by a beautiful girl, so that you might name your canvas "Dark Rosaleen," you would give the world to get Di for your model. She is tall, as a Diana ought to be, and slender though not thin. She gives the effect of fashionable slimness, yet she is all lovely curves and roundnesses. She has a long white throat with a charming upturned chin that has a deep cleft in the middle. It's no exaggeration to say that her skin is as white as creamy milk; and on each cheek, just beneath the shadow under her eyes, is a faint pink stain, as if it had been tapped hard with a carnation, and a little of the colour had come off. Perhaps, if her face has a fault, the nose is too short and flat, but it gives her a sweetly young and innocent look, added to her eyes being set far apart. And the eyes are really glorious: very big and long, with deep shadows under them only partly cast by her thick black lashes. A man once wrote a Valentine verse to Di, in which he remarked that her eyes were "like sapphires gleaming blue where they had fallen among dark grasses"; and it wasn't a bad comparison. The man died of taking too much veronal a year after. Nobody said he had done it on purpose. But I wondered. He was very unhappy the day he said "Good-bye" to Ballyconal. I've never been able to forget his look.

Di's mouth is large, and a tiny bit greedy, but all the more fascinating for that, because it is so red and curved. Her forehead is rather high, really, but she makes it seem only a white line above her level eyebrows, because of the way she likes best to wear her crinkly dark hair: parted in the middle, pushed forward and down, and banded in place by a rope of hair from the back.

That night for the ball at the American Embassy she had it fastened with big, very green jade hairpins. From her little pink ears hung long loops of emeralds (heirlooms in our family, or they would have been sold long ago), and the gown she chose was the same shade of green: some very thin, soft stuff, with one of those new names dressmakers think of in their dreams. It was simply made, and not very expensive; but in it Di looked like a classic personification of Ireland at its loveliest, and I was sure that not the best-dressed girl in the room would be as exquisite as she. I told her this on an impulse, and she was pleased. Yet she sighed. Of course she couldn't help knowing, said she, that she wasn't bad looking. But Venus or Helen of Troy couldn't make a success, handicapped as she was.

"It might be different in some other country," she went on, more to herself than to me. "A country like America, where titles are more of a novelty, and everybody one meets doesn't remember all about one's poor mother."

"Now I must run and get ready, myself," said I, when I had established connection between Diana's most intricate hooks and eyes.
