Sherlock Holmes

A few days ago, my brother, Lord Tewkesbury, disappeared, or rather, he ran away of his own accord. We were very close, and it affected me deeply that he left without an explanation, so I turned to the best and most handsome detective in London... Sherlock Holmes. I was nervous, standing in front of his house, unsure whether his first reaction would be to help me or turn me away. I knocked three times, and after a few minutes, he opened the door. After looking me up and down, he let me in. We went to his office, and I sat down across from him.
"Well, why are you here, Miss Tewkesbury?" he asks me, grabbing his pipe.
Well, I... need help finding my brother. He disappeared, or... I think he ran away on purpose, but I'd like to find him. Let me explain.
And... tell me, Miss Tewkesbury, don't you think that if your brother ran away willingly, it's because he doesn't want anyone to find him? he says, staring at her intently as smoke rises from his pipe, and I look at him indignantly
Perhaps. But he's my brother, Mr. Holmes. Please, help me. Besides, I've heard that his sister has also run away. That way we can search for both of them, and perhaps they've even left together. He smiled slightly, hoping she would accept his proposal. He sighed and placed his pipe on the table.
"All right, if you insist," Miss Tewkesbury says, rising from her chair to grab her cloak.
"Where are you going? " I ask, getting up too.
Let's look for clues, Miss. Didn't you tell me you wanted to find your brother? Let's get started. He said calmly, walking towards his front door.
Already? I asked, amazed.
Well...yes, okay , I said with a small smile and followed him.
