Petra, who until this moment had tasted nothing, now took up her cold cup of tea and drank thirstily, while Dick and Clare became mildly hilarious over a growing volume of anecdotes concerning the inimitable Felix Fairfax, the flirtatious, vanished and banished butler, whom Lewis’ question about Teresa had brought to mind.

Lewis was silent. He was not looking at Petra, but he knew instinctively when she lost her strange, inexplicable fear, and relaxed. A baby, with a pretty young nurse in its wake, was running down the lawn, toward the tea table. Petra had been the first to notice the invasion and welcomed the diversion it brought. Then Clare, following Petra’s eyes, saw the baby.

“Little Sophia!” she cried, quickly on her feet, while anecdotes of Felix Fairfax hung broken off in mid-air. She ran forward a few steps and knelt on the grass, her arms spread wide to receive her little daughter. In that gracious moment Clare was like nothing in the world but a dancing Greek figure on some lovely old vase—all quicksilver, grace and charm. Dick’s face glowed appreciatively. Even Lewis, for that minute, was aware of Clare’s loveliness.

The baby, however, made a swooping detour to avoid the wide-flung, slender arms of the kneeling mother and plunged straight for Petra, her big half-sister. Petra held her off, at arm’s length. “You’ve been in the brook. You’re dirty. You’re muddy. Don’t touch my dress. No!”

The rebuffed cherub commenced to wail but Petra did not relent and draw her into her arms. “No! No!” She repeated it. “Mustn’t spoil Petra’s beautiful, clean dress. No. I’m not going to pick you up.

Then Clare swept down upon them and snatched the baby up. Two muddy palms immediately made their mark on the shoulders of her white frock. But she lifted the delicious little hands and kissed them, one after the other, gravely—delicately. Her eyes, over the baby’s golden head, looked at Petra now with healthy, open accusation, and she held the delicious little body more and more tightly to her, while small wet shoes muddied her skirt.

Clare, looking away from Petra at last, met Doctor Pryne’s puzzled eyes. “I’m going to take little Sophia up to the nursery, if you’ll excuse me for only a few minutes,” she said. “Anyway, I wanted you to see our guest house—the view at its back. You get the river there. Petra will show you. And this is a good time—before Lowell comes along.—Richard, you may come up with us and see what a nice supper a nice cook has sent up to a nice nursery for an adorable baby! Only first we’ll help a nice nurse to wash these precious, dirty paws.... No, Richard, I want to carry her myself. Truly. You don’t mind, Doctor? I always run up to the nursery at little Sophia’s supper time, even in the middle of quite formal parties. But it only takes a few minutes.”

Her eyes, on Lewis’, were replete with meaning. “Now is your time,” they said. “Do make a beginning at helping me understand this strange girl. You can’t deny she is lacking in normal responses. Help me!”

“Good-by, sister,” Petra murmured, and went near enough to lay her cheek for just a breath against her little sister’s hair. “I couldn’t let you spoil my pretty dress, honey. But I do love you!”

At this belated gesture, Clare’s beseeching look at Lewis transformed itself to one of ironic amusement.
