It’s complicated—not your typical underdog becomes hero story. Denver police’s male-dominated homicide boy’s club refused acceptance to Albuquerque transplant Skylar Kayne. Despite her tedious efforts—mistakes made, life and death mistakes. The division chief admitted a hiring error, though not openly, but was desperate for a solution. He needs to rectify this soon, not only to save face but to keep his division unified sans Kayne. Colorado fought one of the worst Arctic troughs they ever experienced. Rain, snow, wind, sleet—none of it helped. Not the gloomy dispositions. Not the biting cold. It was weather for murder. Loathing in self-pity, Kayne found herself alone for a few minutes and snooped through her seasoned partner’s closed case files. She stumbled across a suicide by hanging. After she checked her nails, Skylar glanced at the top page. As she read, she became intrigued. The suicide woman had accidentally run over and killed a lady the previous night. Kayne wondered what she would do in the same circumstance. Two bodies in two days—understandable, but four bodies in four days—inconceivable. And after digging, each appears to know at least one of the others. To complicate matters, four different jurisdictions each closed their case: car accident, hanging suicide, smoke inhalation, and natural cause. Skylar cannot fathom the coincidence and refuses to let it go.
