You've finished this scene

Holmes recalls other harmless puzzles and introduces Peterson, the commissionaire who brought him the old hat. The scene establishes this development clearly and closes before the next step begins, preserving the original passage's order and the limits of what the characters know at this point.
"Precisely. You allude to my attempt to recover the Irene Adler papers, to the singular case of Miss Mary Sutherland, and to the adventure of the man with the twisted lip. Well, I have no doubt that this small matter will fall into the same innocent category. You know Peterson, the commissionaire?"
「そのとおり。アイリーン・アドラーの書類を取り戻そうとした件や、メアリー・サザーランド嬢の奇妙な事件、それに唇のねじれた男の冒険のことだね。まあ、今度のちょっとした一件も、きっと同じ罪のない部類に入るだろう。守衛のピーターソンを知っているね?」
"Yes."
「ああ」
"It is to him that this trophy belongs."
「この戦利品は彼のものなのだ」
"It is his hat."
「彼の帽子なのかい」
