How am I supposed to keep track of this girl? Seems she's friends with everyone in the suburb!

I must have spent 20+ turns in this game with all victims dead or saved, kiting the Poltergeist around with nothing but a guard each turn and a short rest every now and then. I revealed every single other item card in Maple Lane before finally finding Carolyn!
