You woke up one day and your whole family is gone. As if they never existed in the first place. After a week, asking around the city, no one remembers their name, so you headed straight to the one and only - Sherlock Holmes

"What's your case?"

You tell him what happened, but it sounds too crazy to believe

"I'm not into this Harry Potter kind of fan. Stop playing games. Or did Moriarty sent you? Or is it that you want to join my 'team'?"
