Biddy was in the act of handing round the tea when there came the sound of a step outside, and an impatient hand thrust open the door.
"Hullo, Stumpy!" said a voice. "Are you here? What have you done with Miss Bathurst? She's engaged to me for the next dance." Eustace entered with the words, but stopped short on the threshold. "Hullo! You are here! I thought you had given me the slip."
Dinah looked up at him with merry eyes. "So I have--practically. I am on my way to bed."
"Oh, nonsense!" he said, with his easy imperiousness. "I can't spare you yet. I must have one more dance just to soothe my nerves. I've been dancing with a faultless automaton who didn't understand me in the least. Now I want the real thing again."
"Have some tea!" said Scott.
"Thanks!" Sir Eustace sat down on the edge of the table, facing his sister and Dinah. "You're not going to let me down, now are you?" he said. "I'm counting on that dance, and I haven't enjoyed myself at all since I saw you last. That girl is machine-made. There isn't a flaw in her. She's been turned out of a mould; I'm certain of it. Miss Bathurst, why are you laughing?"
"Because I'm pleased," said Dinah.
"Pleased? I thought you'd be sorry for me. You're going to take pity on me anyway, I hope. The beautiful automaton has gone back to her band-box for the night, so we can enjoy ourselves quite unhindered. Is that for me? Thanks, Biddy! I'm needing refreshment badly."
"You would have preferred coffee," observed Isabel.
It was the first time she had spoken since his entrance. He gave her a keen, intent look. "Oh, this'll do, thanks," he said. "It is all nectar to-night. Why haven't you been down to the ballroom, Isabel? You would have enjoyed it."
Her lips twisted a little. "I have been listening to the music upstairs," she said.
"You ought to have come down," he said imperiously. "I shall expect you next time." His hand inadvertently touched the box on the table and he looked sharply downwards. "Here, Biddy! Take this thing away!" he ordered with a frown.
Isabel leaned swiftly forward. "Give it to me!" she said.
His hand closed upon it. "No. Let Biddy take it!"
"Let me!" said Dinah suddenly, and sprang to her feet.
