My Fair Verona by Chey Carner

Ross Lake was a small and quiet town, the kind where everyone knows each other. When Sara Jensen, a twenty-two-year-old graduate of the police academy, took a position with the Ross Lake Police Department, she never expected to see any action. Then one day, a couple of hikers come across a woman's body in the woods. Sara and her veteran partner, Harold Dunn, are thrown into a world of secrets and horror as they investigate her murder. Dunn and Jensen aren't the only ones who want a confession, though. A malevolent spirit is also seeking revenge and clings to the world of the living through the people it knew in life, but the police can't prosecute the dead, so Dunn and Jensen must stop the spirit to save their suspect.
