Sea Castle (Underwater Investigation Unit #4), by Andrew Mayne

Eight stars

First and foremost, a large thank you to NetGalley, Andrew Mayne, and Thomas & Mercer for providing me with a copy of this publication, which allows me to provide you with an unbiased review.

Andrew Mayne returns with his somewhat unique series, set in the heart of Florida. Using a forensic diver as his protagonist, Mayne is able to tackle a different angle to most crime thrillers I have read, while keeping the reader intrigued until the final page turn. Adding some serial murder and cult-like behaviour, Mayne shows that he has all the ingredients for a great novel, sure to keep the reader enthused.

Sloan McPherson has made quite a name for herself in Fort Lauderdale as a member of the Underwater Investigation Unit’s forensic diver. When the body of a young woman’s body is found along the shoreline, Sloan immediately presumes it’s murder, while others ponder the possibility that she might have committed suicide. The clues do not make sense and Sloan is baffled as to what she is seeing in front of her.

Sloan begins poking around, but she is stonewalled by the authorities, as they are sure this was a simple miscalculation by a novice swimmer. Enter Gwen Wylder, who is quite rough around the edges and an outcast with the Miami Police. Wylder is happy to help Sloan, but for a price. Sloan must help by offering her own insight into some cold-cases that Wylder has been amassing, all part of what could be a serial killer who has been conniving while they traipse across Florida without detection.

As Sloan soon sees, her victim fits perfectly into the larger case study and there is proof that a killer could be travelling across the state, killing young women. Another woman goes missing, leaving Sloan and Wylder to race out so they can stop a killer from striking again. As things get more intense, both women find themselves involved in something they could not have expected, where they are not able to extricate themselves with ease. Mayne creates an intense story and keeps the reader hooked with some of his unique perspectives throughout.

It was the first book in this series that alerted me to the work of Andrew Mayne. Since then, I have not been able to get enough, having devoured a few of his series, while always remaining in awe. Mayne knows what he’s doing and keeps things fresh, unique, and on point. Whenever I see a new publication of his, I cannot help but rush to get it, knowing that it will be a stellar piece of writing.

Mayne develops his narrative in such a way that the reader wants to learn more. He knows how to present a tale that balances the criminal element with some strong backstory, all of which is essential to the final product. Great characters, some of whom build their development throughout the novel, provide the reader with some entertainment as they continue with the journey. The forensic perspective, mixed with the plot development, offer something unique, though this book steered away from underwater exploration and more to the chase for a killer. While this is not as enticing as some of the earlier novels, Mayne is still able to keep the reader in the know and dazzle with his writing style!

Kudos, Mr. Mayne, for another great piece of writing!
