After destroying the last known remnants of Angelus Genetics and the evil Dr. Hauser's operations, Detective Hamilton DeShear escapes with Agent Jaden Trinn and their five-year-old ward Constantine to the Bahamas for a vacation - only to be framed for murder as Constantine is kidnapped and Trinn is nearly shot to death.

While preparing for his final round of life-saving treatments, detective Hank DeShear agrees to work with intelligence agent Jaden Trinn and a ruthless killer known as "The Greyhound" to shut down the remaining legs of Angelus Genetics’ illegal, death-plagued genetic engineering program. But the company Dr. Hauser founded plans to continue operating, buying political protection, and stopping any would-be attackers in the harshest, most permanent ways possible.

After completing the biggest case of his career, private detective Hank DeShear returns home to start treatment for a disabling genetic condition that could end his life, but he learns his partner on the prior case has just been murdered. Was he wrong to conclude the secretive killer known as The Greyhound had declared a truce? Or, have disciples of The Greyhound surfaced to carry on with the murders?

Geneticist Lanaya Kim must do what authorities haven’t - tie together the “accidental” deaths of several prominent scientists around the country to show they were actually murdered. Over the past two years, geneticists have died in what appear to be accidents, but Lanaya knows otherwise. If she tells her secrets to the authorities, she risks becoming a suspect or revealing herself to the killer and becoming an open target.
