Then she said: "That child reminds me of somebody, Osterley.

Where did you pick him up ?" "These red Deepings are all alike," said the duke carelessly.
"Oh?
He's a red Deeping, is he?
Who's his father ?" said Lady Salkeld almost briskly.
"It's a secret," said the duke with perfect truthfulness, for he did not know.
Lady Salkeld looked at him, sniffed, and said with some tartness: "Well, I never expected you to be mysterious, Osterley." The duke bore the reproach with patient meekness, and said nothing.

It suited him very well that his sister should be giving her attention to the Lump.

From the Lump nothing was to be learned.
Lady Salkeld's coming made no difference to their lives.

Pollyooly went on her early morning rambles with the Lump; from breakfast to noon she did her lessons and then went for a sedate walk with Miss Belthorp.
After lunch she played with the Lump till it was time to drive out to tea with the duke.
