You've finished this scene

Holmes identifies the family relationship from the different surnames, and Mary confirms that Windibank is her stepfather. She explains that her mother married the younger man after her father’s death and that, at Windibank’s urging, the plumbing business inherited from her father was sold.
"Your father," said Holmes, "your stepfather, surely, since the name is different."
「お父様とおっしゃいますが」とホームズは言った。「姓が違うのですから、継父の方ですね」
"Yes, my stepfather. I call him father, though it sounds funny, too, for he is only five years and two months older than myself."
「ええ、継父です。父と呼んでいますけれど、それもおかしな話ですね。私より五歳と二か月上なだけですから」
"And your mother is alive?"
「では、お母様はご存命ですか」
"Oh, yes, mother is alive and well. I wasn't best pleased, Mr. Holmes, when she married again so soon after father's death, and a man who was nearly fifteen years younger than herself. Father was a plumber in the Tottenham Court Road, and he left a tidy business behind him, which mother carried on with Mr. Hardy, the foreman; but when Mr. Windibank came he made her sell the business, for he was very superior, being a traveller in wines. They got £ 4700 for the goodwill and interest, which wasn't near as much as father could have got if he had been alive."
「ええ、母は元気にしています。ホームズさん、父が亡くなってからあまりに早く、しかも自分より十五歳近く若い人と母が再婚したとき、私はあまりうれしくありませんでした。父はトテナム・コート・ロードの配管工で、かなりの規模の商売を残しました。母は職長のハーディさんとそれを続けていましたが、ウィンディバンクさんが来ると、母に商売を売らせたんです。ワイン商の外回り営業をしていて、とても気位が高い人でしたから。営業権と持分で四千七百ポンドになりましたが、父が生きていたら得られた額には、とても及びませんでした」
