Disappeared by Alex

New day, new case. My business partner walked in holding a brown envelope. I opened it thinking it was a prank or something but it was actually a case. I turned and looked at Skipper. “That’s a bit weird,” I said. Most people come in and tell us the case, not send it in the post. The case was about a little girl who went missing more than a week before. She was last seen in the park. She was with her friends when she disappeared. Her friends ran ahead while she was tying her shoe lace. They say she disappeared but how can she just disappear like that, without a trace?
