John Tullman: Letective Adventures!

"What was that call about?" You ask.
"Oh. Well, a person called and told me that a thief had stolen one of his family's most prized possessions- a harmonica that was created by his great great great grandfather. His brother was convicted for the crime. He claims that there is no way his brother could have committed the crime, so he wants us to defend him and find the true culprit."
"He's asking for a lot from us."
"Yeah. Well, that's the job of a letective. You investigate the crime, then do your position in court."
Your heart is pounding. This is your very first case. Part of you is excited, but the other part is desperately trying to avoid getting involved. What do you say?
