Perfect for you if...

  • You enjoy crime thrillers with morally complicated protagonists who bend the rules because they believe in the outcome.
  • You appreciate Southern noir set in atmospheric locations like Louisiana bayous, where place becomes a character itself.
  • You want a police procedural that explores the psychological toll of hunting killers and the relationships fractured in pursuit of the truth.

Maybe not for you if...

  • You prefer cosy mysteries or crime stories where the law works cleanly and heroes stay on the right side of ethics.
  • You're looking for fast-paced thrillers with quick resolutions rather than dense, character-driven investigations.
  • You find detailed depictions of violent crime disturbing or are sensitive to descriptions of mutilation and murder scenes.

About this book

Terror stalks the streets of Bayou Breaux, Louisiana. A suspected murderer goes free on a technicality, and the cop accused of planting evidence against him is removed from the case. Detective Nick Fourcade refuses to step away, despite having crossed the line before. This case threatens to push him further. Deputy Annie Broussard discovered the woman's mutilated body and still hears echoes of dying screams. She wants justice. But investigating means allying with a man she distrusts and making enemies among her colleagues. It means being drawn into the confidence of a killer. For Annie, pursuing justice means risking everything—including her life. The search for truth leads down a twisted trail through Louisiana's bayous and into the darkest reaches of the human heart.
