Robert Hunter is called to the most vicious crime scene he has ever attended. It is made even more disturbing when the autopsy reveals a poem, left by the killer, inside the body of their victim.

Soon, another body is found. The methods and signature of the murder differs, but the level of violence used suggests that the same person is behind both crimes. Hunter's fears are confirmed when a second part of the poem is found.

But this discovery does more than just link the two killings - it suggests that this is the work of a serial murderer.

With no forensic evidence to go on, Robert Hunter must catch the most disciplined and systematic killer that he has ever encountered, someone who thrives on the victims' fear, and to whom death is a lesson that needs to be taught.
