A Good Girls Guide to Murder, by Holly Jackson, is about a girl named Pippa Fitz-Amobi is in high school and has to chose a project for her senior year graduation credit. She chooses to solve a closed case of a murder in her small town that she thinks should not be closed. The following quote is from page 19, chapter 2.
“When you ask people in town what happened to Andie Bell, they’ll tell you without hesitation: ‘She was murdered by Salil Singh.’ No ‘allegedly,’ no ‘might have,’ no ‘probably,’ no ‘most likely.’ He did it, they say. Sal Singh killed Andie. But I’m just not so sure.” p.19
In this quote Pip is saying how she really thinks that Salil did not kill Andie and that the town is wrong, therefore she will be trying to “solve” the case herself while not getting into the actual case as that could be dangerous. After she figures out that she might be on to something and others involved in the case see this too she begins to contact the police about reopening this case. The whole town is convinced that Salil killed his girlfriend Andie Bell, but even the police case says that they are “almost certain”.
