Dark Dive

A Thriller (Underwater Investigation Unit, Book 5)

By: Andrew Mayne

Narrated by: Susannah Jones

A Wall Street Journal bestselling series.

Searching for a missing diver takes a Florida detective on a deep-diving adventure in a gripping thriller by the Amazon Charts bestselling author of Sea Castle.

After the Underwater Investigation Unit’s disbandment, public outcry ushers Sloan McPherson and her partner, former navy diver Scott Hughes, back into the depths of crime solving. But Sloan’s return comes with a personal case.

Longtime family friend Fred Stafford has disappeared. Left behind: his abandoned truck in the vicinity of an unmarked sinkhole and new findings that have Sloan second-guessing everything she thought she knew about the man. There are his gambling debts, his association with a treasure-hunting band of underwater cavern junkies called the Dive Rats, and most alarming of all, a discovery in Stafford’s storage shed that raises the stakes even higher and plunges Sloan into an unfathomable mystery.

As Sloan’s investigation unfolds, a tragic Florida cold case, local superstitions, and a shocking conspiracy collide. For Sloan, finding Stafford and uncovering the buried secrets of the past soon drag her deeper into the dark unknown than she feared.

Critic reviews

“A solid mystery with an underwater backdrop.” —Kirkus Reviews

“I have read all the entries in this series and will continue to read them as new ones come forth. Why? Because they are highly entertaining and have characters I relate to and admire.” —George Easter, Deadly Pleasures Mystery Magazine

Great book!

Love these characters and cannot wait until the next book comes out! Each book is better than the one before.

What’s next? Can’t wait!

Story: superb! Reader: superb! Characters: Siberia! Author: still amazingly clever, always compelling! Another winning entree in his series of mystery procedurals.

Another great book

I've enjoyed all of Mayne's books. I love the intelligence of his characters and how he includes scientific and archeological explanations that back up parts of his stories.

Another great addition to the Andrew Manye library.

Solid as always. More character development for the series and some setup for a wider universe. Great !

Twisty as always. Love the FL history!

Another wonderful story by Andrew Mayne, full of great lore, daring dives, and would-love-to-know-them characters.

Great story

I listened to the first five books and this is my favorite. Maybe because of the archaeological finds.

Always a Thrill Ride

I love this series. As if the unique and tightly woven storylines weren't enough, the quirky characters provide a touch of excellence. Sloan is a truly unusual individual. She has a distinct way of looking at life, having grown up in and around the waters of South Florida with a treasure hunter for a father. Her long-time relationship with her boyfriend/teenager's father is warm, close, and distinctly charming. Speaking of charming, that man of hers is a complete keeper, being one of the few people who truly understands her and allows her to be who and what she is.

While all the tales in this series have been incredibly interesting, this one took several unexpected curves as it focused just a bit on Florida's pre-history while still introducing us to some of the more slimy residents of the Sunshine State. This is definitely another win for the Underwater Investigation Unit series as well as for the narrator, Susannah Jones, who puts forth distinctly solid and genuine voices for Andrew Mayne's great characters.

These are my favorite!

I love this series and always love when a new book comes out!!! It’s always so interesting to me as well as an exciting listen.

Another Good One

Another good book in the series. The excellent narrator and of course the author kept my interest. I didn't want to pause listening.

Weird Things underwater

If you like finding Weird Things underwater thing this book is for you. A nice continuation of the storyline with some references to dark parts of Florida’s recent past. I was expecting a magic trick or two but in this tale Andrew’s familiarity with OpenAI and Chat-GPT shine through and provide some footings for future books.
