Description
Three men are dead.
All of them killed on Father's Day.
Detective Duke Mantz has spent years trying to forget the case that never sat right-the accidental death ruled closed a decade ago. But when another body turns up, staged with eerie precision and ritual intent, he's forced to confront a pattern no one else wants to see.
Each year.
Each Father's Day.
Another man.
As the investigation unfolds, Duke teams up with FBI profiler Brooke Allen, and the truth begins to surface: these killings aren't random, and they aren't about opportunity. They're about judgment. About fathers who failed. About wounds that never healed.
The closer Duke gets to the truth, the more he realizes the danger isn't just in stopping the next murder-it's in uncovering the one that started it all.
Because this Father's Day, the past isn't staying buried.
And the final reckoning is coming home.
