"Have I offended her?" asked Mary, anxiously. "I'm sorry. I don't seem to place her, although I've been trying to remember all the guests."

"That's Arnold Gibbs's little girl," explained Bill. "She's been telling me things about my party and now she's just discovered who I am."

"Oh! And you let the poor child go on and on, of course. How awfully mean of you. Will you never learn?" Mary frowned at him with all the severity of a sister. "But that's not what I wanted to speak to you about. You've been hiding—and you mustn't! People are asking where you are. Please—please don't spoil things. It's your party and you've just got to be present at it."

Bill made a face.

"I'm tired of being exhibited," he growled. "I'm tired of meeting people who say: 'So this is little Willie Marshall. Mercy, how you've grown! I haven't seen you since you wore knickerbockers. But you're a Marshall, sure enough; you're the image of your father.' I tell you, I'm sick of it!"

"But it's only for once," pleaded Mary. "Now they've met you they won't do it again. But what I want you to do now is to go in and dance with some of the young people. There are some lovely girls in there, and they're just sitting around. Come; I'll introduce you, if you haven't already met them."

But Bill hung back. He did not want to dance at all; he was grateful because his secretary had inadvertently saved him from Arnold Gibbs's little girl. There was woe in his eyes as he looked at Mary. There was every sound reason why his expression should have been different, for Mary, in her party gown from Aunt Caroline, inspired anything but woe. Even she herself was conscious of the fact that she looked nice. Bill was becoming slowly conscious of it himself, although he could not drive the gloom out of his soul.

"Come," she said, peremptorily, hooking her arm in his.

"I'll dance with you," he offered.

"That won't do at all. I'm not a guest."
