Detective Ethan Cross has dedicated years to patrolling the streets of Graystone City, a metropolis plagued by corruption, crime, and shadows that engulf the innocent. When a high-profile murder shakes the political elite, Ethan discovers a disturbing pattern linking the crime to his own family bloodlines he believed were long forgotten. As the city's most sinister secrets come to light, Ethan must maneuver through a labyrinth of deception, betrayal, and greed, where every ally may turn out to be an adversary, and every truth conceals a falsehood. Racing against time, he must face the sins of the past to apprehend a killer whose motives are as personal as they are lethal. In Bloodline in the City, loyalty is put to the test, justice becomes a gamble, and the city never forgets.
