Cryptic Code

You are a new female 'employee' for the most recent mafia gang, The Cryptic Code, and you are unaware of how good you are. Until a strange man approaches you with a letter. The letter read,
"Dearest (Y/N),
I'd like for you to meet with me at 12:00 p.m. sharp on top of the large, grey i.n.c. building. It's for a.. how do you saw it.. business meeting. You see, (Y/N), if you don't come to this meeting, well, your father would have to see the, 'shit end of the stick', if you must. I look forward to seeing you there.
-Carter Gantus"
This angered you. You see, if this man even laid a hand on your father, he'd be dead at a snap. This is because, well, he's the boss of The Cryptic Code gang. Therefore, they'd have his back, no matter what. So now, your adventure awaits.
