From New York Times bestselling author Gilly Macmillan comes this original, chilling and twisty mystery about two shocking murder cases twenty years apart, and the threads that bind them.

Twenty years ago, eleven-year-olds Charlie Paige and Scott Ashby were murdered in the city of Bristol, their bodies dumped near a dog racing track. A man was convicted of the brutal crime, but decades later, questions still linger.

For his whole life, filmmaker Cody Swift has been haunted by the deaths of his childhood best friends. The loose ends of the police investigation consume him so much that he decides to return to Bristol in search of answers. Hoping to uncover new evidence, and to encourage those who may be keeping long-buried secrets to speak up, Cody starts a podcast to record his findings. But there are many people who don’t want the case—along with old wounds—reopened so many years after the tragedy, especially Charlie’s mother, Jess, who decides to take matters into her own hands.

When a long-dead body is found in the same location the boys were left decades before, the disturbing discovery launches another murder investigation. Now Detective John Fletcher, the investigator on the original case, must reopen his dusty files and decide if the two murders are linked. With his career at risk, the clock is ticking and lives are in jeopardy…

Why did I choose to read I Know You Know?

If you read my article The most anticipated books of Fall 2018, then you know I mention this book as one of the books I wanted to read this fall (which I did). I had already read a book by this author, What She Knew, and liked it. Also, I love a good mystery/police novel, which this book promised to be.

I also read some reviews of this book that said that it was written as if it was a Podcast, which intrigued me. I recently started listening to some Podcasts and I’m hooked: as such, I was quite curious to see how it would pan out in the book.

I bought this book back when it came out, in September of this year, but I only got around to reading it this month. Read on to find out how I liked it!

What’s it about?

This book follows the case of a twenty-year old murder of Charlie Paige and Scott Ashby being reinvestigated by their childhood best friend, Cody Swift, who shares his findings in a Podcast. Cody Swift lost his two best friends some twenty years ago, when he was just a boy himself. While he has moved away, grown up and gotten a career for himself since then, Cody comes back home to re-open the case and find out the truth. Because while a man was convicted and found guilty of the murders, Cody doesn’t believe the case is resolved… Has an innocent man been serving a life sentence, while the real perpetrator walks free?

Also involved in the story is the police officer who discovered the bodies of the two 11-years-old boys, John Fletcher, along with his partner. In the story, the detectives are concurrently working on a murder case whose victim was discovered at the exact same place the two boys were found and whose body had been there a while. Through some flashbacks, we also get an insight into the investigation that happened twenty years ago.

Another narrator is Charlie Paige’s mother, Jessica Paige. Jess has rebuilt her life and now has a new family. She wants the past to be left well alone, for more than one reason. Some reasons are more mysterious than others… Jess won’t stop at anything to make sure Cody Swift’s investigation doesn’t uncover some truths she wants left buried, for her sake and her family’s.

What did I think of I Know You Know?

By now, it is a known fact that I love a good mystery/police novel. And I Know You Know by Gilly Macmillan sure delivered on that point.

I give it four stars and a half. I really enjoyed the original format, with some chapters being narrated as if they were an actual transcript of a Podcast. I’ve only recently started listening to Podcasts, and I think they’re becoming quite popular, so I Know You Know is a bit ahead of its time (which is cool!).

Basically, what I enjoyed the most was the writing style, how it jumped narrators from chapter to chapter, the flashbacks, the chapters that were written as a Podcast: it kept you hooked the whole book. The whole investigative aspect of the novel really stands out and makes it interesting.

The more you read, the more you learn about what happened that terrible night the two boys went missing. At the end, you think you have it all figured out, until something unexpected comes out and takes you by surprise, which makes for a good ending. I really enjoy being surprised when I read.

I won’t say more, in case I spoil too much. I definitely recommend this book for those who enjoy a good police novel, with different narrators that really keep you on your toes!
