Body in the Wall by Rita Herron

This place had been her home…now it was a crime scene.

The sooner Special Agent Macy Stark clears out her mother’s house, the sooner she can escape her small town and shameful past — until she discovers a body in the wall and her childhood nightmares return. Handsome local Sheriff Stone Lawson joins the cold case, helping Macy locate her missing mother and uncover a dark web of secrets about both her parents. But someone’s willing to kill to keep the past hidden…for good.
