Summary

A Good Girl’s Guide to Murder follows Pip Fitz-Amobi, a high school student who chooses a closed murder case for her final project. The town believes that Andie Bell was murdered by her boyfriend, Sal Singh, who then took his own life. Case closed. End of story.

But Pip isn’t convinced.

As she begins digging into the case, interviewing people, revisiting timelines, and uncovering inconsistencies, what starts as a school project slowly turns into something much darker. The more she uncovers, the clearer it becomes that the town has been holding onto a convenient version of the truth.

And not everyone wants the past to be reopened.

The story unfolds through a mix of narrative chapters, interview transcripts, and project notes, which gives it a grounded, almost documentary-like feel. You’re not just reading a story, you’re piecing together a case.

“Everyone lies. Everyone hides things. Some lies are just bigger than others.”

My Thoughts

What worked really well for me was Pip as a character. She is curious, persistent, and smart without feeling unrealistic. Her growth from a student working on an assignment to someone emotionally invested in justice feels natural.

The structure of the book deserves mention too. The mix of formats makes it engaging and fast-paced. It reminded me of following a real case file rather than a traditional novel. That kept me turning pages without effort.

The tension builds steadily. It doesn’t rely on cheap shocks. Instead, it slowly tightens the grip as the stakes become more real for Pip.

“You can’t just rewrite the truth because you’re scared of it.”

That said, the book isn’t without its flaws.

At times, the plot leans a bit too heavily on coincidences. Certain discoveries feel a little too convenient, especially for a high school student with limited resources. Also, a few side characters could have been explored with more depth. They serve the plot well, but don’t always feel fully alive.

Pacing-wise, the first half is more investigative and slow-burn, while the second half accelerates quickly. Personally, I enjoyed that shift, but it might feel slightly uneven to some readers.

From a reading experience standpoint, this was a smooth and engaging read. I finished it in a couple of sittings. It has that rare quality where you tell yourself “just one more chapter” and suddenly it’s much later than you planned. However, overall I like it and I recommend it to read it once. For me its a one-time-read book

What Stayed With Me

How easily a narrative becomes “truth” when repeated enough.

How comfortable people are with closure, even when it’s built on doubt.

And how dangerous curiosity can become once it starts uncovering real consequences.

“It’s not always the person you suspect. Sometimes it’s the one you trust.”

If you enjoy character-driven mysteries with a modern, true-crime feel, this book will stay with you.

Final Review

This is a well-crafted, engaging mystery that balances suspense with emotional depth. It’s not perfect, but it knows how to keep you invested and thinking. Pip’s journey is what makes it work, more than just the mystery itself.

I went in expecting a simple YA thriller and came out genuinely impressed by how layered it felt.
