Unknown means

the long version

In *Unknown Means*, Evelyn James is called to investigate two different murders of women in very high-security penthouse suites. When her best friend Marissa, the DNA analyst, is attacked by the same man, things get personal. She’s distracted by pressure from her homicide detective boyfriend about their future together and also by a harrowing crime scene in the salt mine underneath Lake Erie. A third murder convinces her that the killer’s choice of victim is anything but random.
