One split second can change a life. But what happens when the consequences don’t come to light until forty-five years later? In One Split Second, Robert Dugoni the past and present comes together in another intriguing Tracy Crosswhite mystery.
I’m a huge Robert Dugoni fan, and I always look forward to another book in his Tracy Crosswhite series. One Split Second is the latest installment. Although it’s part of a series, I think it can easily be enjoyed as a standalone novel.
One fun thing about reading this book was that I started it while vacationing in Washington State! Since the story takes place in Washington, too, it made the setting even more enjoyable for me. There’s just something about reading a book set in the same part of the country you’re visiting that makes it a little more special.

My Thoughts on One Split Second:
🔎 A Mystery That Connects the Past and Present
The story is told through two timelines, which I thought worked really well. In the past, a young girl disappears while babysitting, leaving behind an unsolved mystery. In the present, Tracy’s friend Jenny, a fellow law enforcement officer, is accused of shooting a man who may have been connected to that long-ago disappearance.
I enjoyed how Dugoni slowly connected the past to the present. There were enough twists and unanswered questions to keep me interested, and I was curious to see how everything would eventually come together.
❤️ Tracy and Dan Make a Great Team
One of the things I particularly enjoyed about this book was seeing Tracy work alongside her husband, Dan. Since Dan is an attorney, he brings a different perspective to the investigation. Tracy has her detective instincts, while Dan approaches things from the legal side.
I liked watching them work together and seeing how their different strengths helped move the case forward. I’ve also enjoyed watching their daughter, Daniella, become a bigger part of their family story with each new book.
🎧 Sometimes Listening Is Better Than Reading!
I read about half of this book and listened to the other half on Audible. Here’s something that doesn’t happen very often for me. I actually think I enjoyed listening to this book more than reading it! Emily Sutton-Smith did a wonderful job with the narration, and I found myself looking forward to the times when I could listen. I’m usually pretty particular about audiobooks, so when I find one that makes me prefer listening over reading, that’s saying something!
🧩 An Ending That Touched My Heart
I really liked how Dugoni brought everything together at the end. One of the things I appreciate about a good mystery is finally finding out what actually happened, especially when the story involves something that took place so many years earlier. What surprised me, though, was how emotional the ending made me.
There was a touching part about marriage, love, and what it takes to make a marriage last. I wasn’t expecting a mystery to choke me up, but those words really touched my heart. I love when an author can give me a good mystery to solve and then unexpectedly add something meaningful about life and relationships. That made the ending even more memorable for me.
📖 Don’t Skip the Acknowledgments!
Now, here’s something I really want to mention because it ended up being one of the most meaningful parts of the book for me.
Robert Dugoni’s acknowledgments.
Dugoni shared that his mother passed away last year and talked about the feeling of being an orphan when both of your parents are gone, even when you’re an adult. I could relate to his words so much. Having lost both of my parents, I understand that feeling. No matter how old you are, there’s something about realizing that both of your parents are gone that is hard to explain unless you’ve experienced it. Reading his heartfelt thoughts really touched me.
I’m already a huge Robert Dugoni fan, but reading something so personal from him made me appreciate him even more. It was a reminder that behind the wonderful stories he writes is a real person who experiences the same love, loss, and emotions that the rest of us do.
I also enjoyed reading about where he got the inspiration for this particular story. I always find it interesting to learn what sparks an author’s imagination. And that brings me to something I don’t understand.
Why aren’t the acknowledgments included in this Audible version?
I enjoyed the audiobook tremendously, but I would have missed these personal reflections entirely if I hadn’t also been reading the book. I think that’s a shame. Sometimes an author’s acknowledgments are nothing more than a list of people they want to thank, but other times, like in this book, they share something deeply personal. Those words can create a connection between the author and the reader that goes beyond the story itself. Audiobook listeners deserve that experience, too!
In this case, the acknowledgments made me like Robert Dugoni even more than I already did. And considering how much I already enjoy his books, that’s saying something!
⭐ My Final Thoughts
Although One Split Second wasn’t my favorite book in the Tracy Crosswhite series, it was still a good mystery that kept me interested from beginning to end.
What I’ll remember most, though, are the unexpected emotional moments. The thoughts about marriage and lasting love near the end, along with Dugoni’s personal reflections in the acknowledgments, gave this book a little something extra.
Sometimes it’s not just the mystery that stays with you after you finish a book. It’s the words that touch your heart.
📝 Extra Credit Reading: When the Past Refuses to Stay Buried
If One Split Second by Robert Dugoni kept you guessing, here are three more mysteries that deserve a spot on your TBR list. From cold cases to determined female detectives, these books prove that some secrets don’t stay buried forever!
1. A Dead Draw by Robert Dugoni
Why? If you’re not ready to say goodbye to Tracy Crosswhite, this is the perfect choice! Another suspenseful investigation featuring Tracy, with a dangerous game of cat and mouse, interesting characters, and plenty of twists. It’s also the book immediately before One Split Second in the series.
2. The Waiting by Michael Connelly
Why? If you enjoyed Tracy digging into a decades-old mystery, you’ll appreciate Detective Renée Ballard and her work with the LAPD’s Open-Unsolved Unit. With multiple cold cases, including the infamous Black Dahlia murder, this is another mystery that proves the past doesn’t always stay in the past.
3. In the Blink of an Eye by Jo Callaghan
Why? If you liked Tracy’s determination and investigative instincts, meet Detective Kat Frank! She tackles cold cases with an unusual partner—an artificial intelligence detective. It’s a fascinating mix of traditional police work, technology, and human intuition, with some great twists along the way.
Disclosure: Thank you to NetGalley, Thomas & Mercer, and Robert Dugoni for my advance copy of this book. This is my honest opinion.
