How do you write a story where the antagonist is a popular girl who is actually a ghost who was killed in the school and came back as a serial killer killing kids just like the kids that are like her, and the girl gets partnered up with the protagonist who’s your typically nerdy girl and they have to make a film like history documentary about the schools history, and they film all the memorable places where kids went missing, but that memorable places are actually where all the missing kids were killed by the antagonist and the antagonist knows a little too much about all the history. The protagonist keeps finding memory card at the memorable places and at the end of the story she decides to play all the memory cards together and finds out that it’s other kids filming the schools history at every place they went but with the antagonist and then you saw their dead body, so the protagonist is disgusted and doesn’t know what to do but she’s gonna obviously show someone this but before she does she gets killed by the antagonist and the antagonist goes to class and does the history project. How would you trick the reader? And drop hints that the antagonist is a serial killer ghost? And for the ending how do you trick the audience into thinking the reader doesn’t die but actually is?
I am so sorry, it’s a very specifically long question!!
