Chapter 1: Cop Sirens

Y/N is stuck in the middle of a murder taken place in her worn apartment. All is dull and fixed until Sal, a boy from Jersey moves in next door. Will Y/N be able to keep up with Sal as well as unpuzzling a mystery that may involve more than one story, one scapegoat, and one back story that may lead them to another possibility? I don't know, just read it or something.
