Robert Hunter is called to the most terrifying crime scene he has ever visited. He becomes even more worried when, during the autopsy, a verse of a poem left by the killer is found in the victim's body.
Before long, another corpse is found. The methods and signature of the killer are different, but the degree of violence used suggests that the same perpetrator is behind both crimes. Hunter's fears are confirmed by the discovery of the second part of the poem. However, this discovery not only connects the two murders, but it is already clear that it is the work of a serial killer.
Despite the lack of forensic evidence, Robert Hunter must catch up with the most disciplined and systematic killer he has ever encountered; a perpetrator who revels in the victim's fear and for whom death is a lesson that needs to be taught.

Genesis is the twelfth novel in the series about detectives Robert Hunter and Carlos Garcia.
