Genre: Crime Thriller

Release Date 06/20/2023

In a sleepy little parish just outside of New Orleans, murder is no rare occurrence.

Sergeant Lance Knight has a pile of unsolved homicide cases on his desk. On the surface, none seem to be connected. The victims are all men with money or power. An investment banker, a lawyer, and a local politician. They don’t socially run in the same circles. Lance can’t find a connection.

Working closely with coroner Gina Goodwin, Lance and Gina discover a pattern. Three unrelated things the bodies all have in common—a string of lethal connections. Is it just a coincidence, or is it something more?

Things heat up when Lance realizes he’s getting close to finding the killer, and everything spirals out of control. Can he piece it together before it’s too late?


Publishers Weekly says, "Lethal Connections pulses with spry dialogue, surprising bursts of tension and danger, and a plot as slippery as a swamp copperhead. For all the fast-moving procedural fun, though, Knight possesses an insightful perception that imbues the storytelling with emotional weight and resonance."

In the swamps of Louisiana, a body is discovered floating in the murky waters of the Wetlands Observatory. Not an unusual day for Detective Lance Knight from the nearby St. Bernard’s Sheriff’s Department. The manner of death, though, and the case that follows prove anything but. When more victims are discovered around the waters of Chalmette, Louisiana, Lance and the coroner, the indomitable Gina Goodwin, discover a most unusual common thread: each has venom in the bloodstream, from what Gina describes as “snakes with a venom I’ve never encountered before.” (And she’d know—she adores herpetology.) From there, the case slithers into surprising territory, including the underbelly of a drug ring operated by a reputed witch practicing black magic.

Lethal Connections pulses with spry dialogue, surprising bursts of tension and danger, and a plot as slippery as a swamp copperhead. For all the fast-moving procedural fun, though, Knight possesses an insightful perception that imbues the storytelling with emotional weight and resonance. Insights into the life of the widow of a victim who cheated on her, for example, bring welcome humanity to the case, as does the winning repartee between the detective and a smirking coroner, quick to deploy the “stink-eye” when appropriate, who has it in her to star in her own mystery series.

The three co-authors’ voices and interests blend into unison but also likely enrich the varied personalities and areas of expertise of this strong cast of characters. Gina’s introduced, in one scene, “elbow deep in internal organs,” while Lance struggles, a bit, with questions like whether he should pull out a chair for her at an Italian restaurant. His minor uncertainty is the kind of winning detail that keeps readers invested, not just in the bodies discovered among the reeds but in the sleuths on the case. The mystery is crisply told, the killer a surprise, and local color and folklore, is engaging.

Takeaway: A detective facing Louisiana poisonings may find the killer too close for comfort.

Great for fans of: Tess Gerritsen, D.J. Donaldson.

Lance Knight, a homicide detective in New Orleans, has his work cut out for him when bodies begin to stack up. He teams up with Gina, an intelligent coroner who doesn’t give up so easily to solve a challenging case. Thomas Wilcox, a man who was dumped in the swamp with a distinct mark on his body, is just one of many that end up dead. Are these deaths connected? Is there a serial killer on the loose? As the investigation deepens, Lance soon becomes a target. Unsure of whom to believe, he knows one thing, he must find the killer before they find him.

The story immediately opens with drama and suspense, and I was instantly hooked. The authors provide readers with a captivating narrative that will keep them on the edge of their seats. Lance is passionate about his work, and that takes precedence over anything in his life. Gina is the coroner who is methodical, intelligent, and also passionate about her work.
