The finale to A Good Girl's Guide to Murder series. By the end of this mystery series, you'll never think of good girls the same way again... Pip is about to head to college, but she is still haunted by the way her last investigation ended. She’s used to online death threats in the wake of her viral true-crime podcast, but she can’t help noticing an anonymous person who keeps asking her: Who will look for you when you’re the one who disappears? Soon the threats escalate and Pip realizes that someone is following her in real life. When she starts to find connections between her stalker and a local serial killer caught six years ago, she wonders if maybe the wrong man is behind bars. Police refuse to act, so Pip has only one choice: find the suspect herself—or be the next victim. As the deadly game plays out, Pip discovers that everything in her small town is coming full circle... and if she doesn’t find the answers, this time she will be the one who disappears...

Pip is not a detective anymore. With the help of Ravi Singh, she released a true-crime podcast about the murder case they solved together last year. The podcast has gone viral, yet Pip insists her investigating days are behind her. But she will have to break that promise when someone she knows goes missing. Jamie Reynolds has disappeared, on the very same night the town hosted a memorial for the sixth-year anniversary of the deaths of Andie Bell and Sal Singh. The police won't do anything about it. And if they won't look for Jamie then Pip will, uncovering more of her town's dark secrets along the way... and this time everyone is listening. But will she find him before it's too late?
