YMMV / Kovac & Liska

• Complete Monster: Frank "Fitz" Fitzgerald—real name unknown—is a seemingly unremarkable truck driver who is actually the prolific murderer and rapist known as "Doc Holiday" who targets women and girls on holidays, driven by aspirations of notoriety. Introduced in "The 1st Victim" reporting his most recent victim in Minneapolis to Detectives Sam Kovac and Nikki Liska whilst posing as a concerned citizen, Fitz abducts women and girls throughout Central United States, subjecting them to prolonged torture and sexual abuse before killing them and disposing of their bodies, having successfully killed eight women. In The 9th Girl, when a haphazard attempt at framing him wounds his pride, Fitz targets the reporter Dana Nolan, intending to make her his "masterpiece". Fitz's actions are shown in Cold, Cold Heart to have left Dana traumatized even after his death.
• Nightmare Fuel:
  • There is a certain element of terror that can arise from knowing that a seemingly normal individual can actually be a serial killer, such as the Cremator or Doc Holiday.
  • It can be unsettling, knowing that it is not unheard of for people to be murdered by someone they know, even among their own family. Even more unsettling, people are more likely than not to know their killer.
• Squick: The novels have their fair share of unsettling imagery, from cigarettes on skin, broken ribs, and blunt force trauma to charred flesh.
