A Good Girl’s Guide To Murder by Holly Jackson

If you like murder mysteries, true crime, or stories where an amateur investigator becomes increasingly obsessed with uncovering the truth, A Good Girl’s Guide to Murder by Holly Jackson is an easy book to add to your list. The premise is straightforward enough: five years after a teenage girl is murdered in a small English town, high school student Pippa Fitz-Amobi decides to investigate the case for her senior project because she doesn’t believe the person everyone blames actually committed the crime.

That decision probably would have been perfectly reasonable if Pippa had simply written a paper about inconsistencies in the investigation, turned it in, and moved on with her life.

Of course, that’s not what happens.

Pippa becomes increasingly invested in figuring out what actually happened to Andie Bell, a popular teenage girl whose disappearance and murder became one of those cases that the entire community thought it understood. The police concluded that Andie’s boyfriend, Sal Singh, killed her before taking his own life, effectively ending the investigation in the eyes of the public.

Pip isn’t convinced.

Her initial interest comes partly from knowing Sal and remembering him as a kind person who doesn’t fit the image of a murderer that everyone else has accepted. As she starts looking into the case, she discovers that the evidence against him isn’t nearly as straightforward as the town has been led to believe.

She also brings Sal’s younger brother, Ravi, into the investigation, and that relationship becomes an important part of the story. Ravi has spent five years living with the consequences of his brother being labeled a murderer, while Pip is approaching the case from the outside and trying to determine whether the official story actually holds together.

Their investigation quickly turns into something much larger than a school assignment.

Pip starts interviewing people who knew Andie, digging through old messages and records, looking at timelines, and following leads that were either overlooked or dismissed during the original investigation. The more people she talks to, the more complicated Andie’s life becomes, and the more difficult it becomes to separate what people knew from what they wanted everyone else to believe.

That is one of the strongest elements of the book for me.

Andie isn’t presented as a perfect victim, and Sal isn’t simply presented as a misunderstood boy whose reputation needs to be restored. Both characters become more complicated as Pip digs into their lives, and the investigation forces her to consider how easily a community can create a narrative around people when the actual truth is much messier.

Pip herself is also a fun protagonist because she has the exact combination of curiosity and stubbornness that makes for a good amateur detective and a terrible decision maker.

She knows she is getting into situations that could become dangerous, yet she continues investigating because she cannot accept an answer that doesn’t make sense to her. As the case progresses, the consequences become more serious, and what started as a school project begins to feel much more like a genuine investigation.

Then Pip starts receiving threats.

That changes the entire dynamic of the story because now she isn’t simply trying to prove that Sal might have been innocent. Someone knows what she is investigating, someone doesn’t want her to continue, and Pip has to figure out whether the threats are connected to the original murder.

From that point forward, the book becomes increasingly difficult to put down.

Jackson also does a good job with the structure. The inclusion of Pip’s project notes, interview transcripts, messages, research, and other pieces of evidence makes the book feel like you’re following along with her investigation rather than simply being told what happened.

It gives you enough information to develop your own theories, which is exactly what I want from a mystery.

Of course, not every twist completely caught me off guard, and some of the developments were easier to anticipate than others. That didn’t really bother me because the enjoyment came from watching Pip connect the dots and seeing how the different pieces of the investigation fit together.

The book also manages to balance the darker elements with some lighter moments, particularly through Pip’s relationship with Ravi. Their partnership develops naturally because they each have different reasons for wanting answers, and their relationship gives the story some emotional balance without taking over the central mystery.

I think that balance is important because A Good Girl’s Guide to Murder deals with some pretty heavy subjects. Murder is obviously at the center of the story, but Jackson also explores drugs, abuse, manipulation, racism, sexual exploitation, grief, and the ways people can use reputation and social standing to control how others perceive them.

Despite that, the book never becomes so heavy that it loses its momentum.

It remains a fast-paced mystery that keeps giving Pip another question to answer, another person to interview, or another piece of evidence to examine. Even when she thinks she has finally figured something out, there is usually another detail that needs to be reconciled.

That constant investigation is what kept me reading.

I also think this is a good example of a YA book that can easily appeal to readers who don’t typically gravitate toward young adult fiction. The characters are teenagers, so their age naturally affects the way they interact with one another and the resources available to them, but the central mystery doesn’t feel watered down because of it.

Pip isn’t a professional detective. She doesn’t have access to police databases, forensic experts, or unlimited resources. She has a notebook, a lot of questions, a willingness to annoy people, and a determination to keep going when everyone else tells her the case is already solved.

Those limitations actually make the investigation more engaging because Pip has to figure things out through conversations, research, observation, and persistence.

And persistence might be her defining characteristic.

The title gives you an indication of the tone, but the book itself is considerably darker than the title might suggest. It has the energy of a teenage mystery while dealing with genuinely disturbing circumstances, so I would recommend checking the content warnings if you’re sensitive to violence, sexual assault, drug use, or other difficult subject matter.

For readers who enjoy mysteries, though, this is a really easy recommendation.

A Good Girl’s Guide to Murder gives you a murder, a questionable official investigation, a determined amateur detective, plenty of suspects, hidden relationships, conflicting stories, and enough evidence to keep you forming theories as you read. It moves quickly, the investigation remains at the center of the story, and the supporting characters give the mystery enough depth that it never feels like Pip is simply moving from clue to clue without any emotional investment.

I also appreciated that the central question isn’t simply, “Who killed Andie Bell?”

As Pip digs deeper, the question becomes why so many people were willing to accept the original story, what they knew, what they chose not to say, and how much damage can come from deciding that you already know who someone is.

For a book that begins as a high school project, Pip gets herself into an impressive amount of trouble.

Fortunately for us, that makes for a very entertaining mystery.
