A wounded private investigator pursues a deadly black widow to the cozy small town of Heart Lake.

Ashley Perkins takes a bullet in the line of duty and barely survives it. While on the road to recovery, she resigns from the Dallas Police Department and pursues a lifelong dream of becoming a private investigator. Her first case involves a trail of bodies — wealthy men who didn’t survive their encounter with an enterprising young woman she nicknames the Black Widow.
