"A lot," said the duke firmly. "You know how like Marion she is. Why, even Mrs. Hutton, who'd been with Marion for years, couldn't tell them apart. Well, I want Mary Bride to be Marion."

"The deuce you do!" cried the Honourable John Ruffin.

"Yes," said the duke in the tone of a man who had quite made up his mind. "I want her to come and live at the court as Marion. I'm going to run her as my daughter, Lady Marion Ricksborough."

"But what on earth for?" cried the Honourable John Ruffin in a tone of the liveliest bewilderment.

"Why, don't you see? At first Caroline will be awfully cockahoop at getting her own way. Then she'll begin to see that Marion's out in the cold, and I've got another daughter in her place. Then she'll kick like fury. She'll send Marion back in a brace of shakes to take her proper place. Then it'll be my turn to kick. I shan't be taking any Marion—at least, not without Caroline comes back too," said the duke with an air of uncommon animation.

He was looking brighter than ever the Honourable John Ruffin had seen him. His eyes were positively gleaming with a manly fire.

"By Jove—by Jove!" said the Honourable John Ruffin softly.

"I thought you'd see it," said the duke complacently.

The Honourable John Ruffin rose from his chair, strode solemnly across the hearthrug, seized the duke's hand, wrung it, and in a voice trembling with emotion said:

"Osterley, I have done you an injustice. I have underrated your intellect. Under that mild and irritated appearance you hide genius—veritable genius. The idea is, as you say, roundabout, but it will work. It will certainly work. You are dealing with a woman."
