Read the clues. Decode the science. Reveal the murderer.
That's Reilly Steel's mantra. Find the answers, solve the crime. But the Quantico-trained forensic investigator is finding her skills aren't enough when a ferociously intelligent killer strikes Dublin.
The modus operandi is as perplexing as it is macabre. What connects the two seemingly disparate, high-profile victims?
Their corpses refuse to give up their secrets and the crime scenes prove a forensic investigator's worst nightmare. Reilly soon suspects that she may be dealing with a killer - or killers - who know all about crime scene investigation.
The police are just as frustrated by the crimes' impenetrable nature and it's only when a third murder occurs - equally graphic and elaborate in its execution - that they discover that this particular killer is using a very specific blueprint for his crimes.
Who is the killer's next victim, the real target? And what's his endgame?
