Whispers of the Crimson Trail follows Detective Lucas Morgan as he embarks on a relentless pursuit of a serial killer whose gruesome crimes start to become personal. Lucas, along with criminal psychologist Ava Callahan, uncovers a series of murders that, at first glance, seem unrelated but slowly reveal a chilling pattern rooted in the killer's obsession with art, the human psyche, and the darkest corners of their victims' lives.
As Lucas and Ava get closer to discovering the identity of the killer, their bond deepens, but so does the danger. The killer's attacks grow more unpredictable, and it becomes clear that Ava is not only a target but is tied to the killer in ways she never imagined.
