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.

Great story line

I feel as if some parts with the first body's should of been told more about over all good

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.

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.
