Lethal Design

Some deaths are designed.
Lethal Design

Some deaths are designed.

The death looks routine. No foul play. No reason to dig.

But Frank Travers has seen enough manufactured coincidences to know when a clean scene feels wrong. When professionals with no addiction history begin dying along eerily similar paths, Orlando Prime is pulled into a pattern spreading quietly across the city.

Someone patient and invisible is engineering the outcomes.

As Frank’s task force chases separate leads through Orlando’s corridors of power, old cases, and carefully hidden networks, the threads begin pointing to the same dark center. KC’s investigation may have found the first crack, but what waits underneath is bigger than one death, one building, or one case.

The closer they get, the more dangerous the truth becomes. Some designs were never meant to be uncovered, and exposing this one may cost more than any of them are prepared to pay.

Perfect for fans of Terri Blackstock and Lynette Eason who love fast-paced, clean crime thrillers with the intensity of Criminal Minds and the grit of NCIS.

Follow Kylie “KC” Cassidy and the Orlando Prime task force as they take on the cases no one else can crack, starting with Lethal Design.
