 In Bill Bennett’s sprawling crime novel Swimming with Manatees, a spate of murders disrupts the calm of a seaside community in Florida.

 

When April Seagram, a BioSphere pharmaceuticals employee, is found dead wearing a life vest and wading on the shoreline in Crystal Cove, expert police detective Ava Martinez suspects April was murdered, and the crime scene was staged. April’s demise draws Martinez into a labyrinthian search for truth— no matter how dangerous it is, who it exposes, or what it demands from her personal life. Intrepid and dutiful with a veiled vulnerability, Ava, alongside Chief of Police Ben Crenshaw and other police officials, uncovers evidence of a far-reaching conspiracy to bury a marine biologist’s research despite its potential to revolutionize the treatment of illness.

 

As more characters are murdered and pressure on Ava to solve the case mounts, elements of a police procedural emerge. Suspects are plentiful, including BioSphere executives; an in-the-know townie; a Marine Institute senior researcher; a biker gang; a sculptor; and a fellow detective. Many mask their motivations, yet their centrality to the story isn’t always convincing. While this obscurity strives for narrative intrigue, convoluted details and erroneous exposition proves baffling rather than inventive. The character of Mavis Leigh comes to mind: is she a conniving villain or an “unexpected ally?” It’s murky business tackling Mavis’s dubious characterizations.

 

The novel offers a passable storyline rendered in confident and expressive prose, providing key descriptions of pharmaceutical corporate greed, manatee and environmental exploitation, and the Floridian climate. Additionally, the story is grounded in plot-driven, pragmatic dialogue. 

However, perplexing plot points, repetitive words and phrases, nebulous techno-jargon, and superfluous characters overwhelm the narrative’s successes, resulting in a frustrating reading experience. For example, Ava reflects on her confrontation with Crystal Cove’s mayor (who’s misidentified as “town manager”), yet the scene isn’t in the book. “BioSphere” is sporadically spelled “Biosphere,” and an overreliance on “flicker” and “like a warning” limits creative impact.

 

A muddled conclusion establishes the characters’ return in a future series, but ultimately Swimming with Manatees requires thorough revision to entice readers.

 

 Also available in paperback and e-book.
