Sherlock loved his wings and took pride in them. He loved stretching them out and feeling the wind in them. Although he had to be careful. Not everyone in the world had wings and not everyone would be accepting of them. He knew his brother had them but that's the only person he knew. They would make weekly trips out to the countryside so they could use their wings and be truly happy. One week Mycroft couldn't go with him so Sherlock went without him. A man saw and decided to sit and watch. Who is this man and what does he want?
