Katt & Mause The First Sin

Every crime scene tells a story. This one was written. Detective Benjamin Mause sees patterns-structure, logic, precision. Livian Katt sees power-people, motive, and the architecture beneath every decision. Together, they're one of the best investigative pairs in the country. But when a string of meticulously staged murders emerges, each more deliberate than the last, the case begins to shift. These aren't random acts of violence.
They're compositions. And someone is designing them with purpose. As the investigation deepens, the line between detective and participant begins to blur. The killer isn't just leaving clues-they're building something. And Mause and Katt may be closer to the center of it than they realize. Some truths don't surface in evidence. Some are placed.
