Embers of Evidence - An MM Romance Thriller. Critical Trace Crime Files, #1

At first, the Henley farmhouse looks like an ordinary tragedy: an old appliance, a fatal fire, a small-town department ready to close the file. But Dr. Cassian Holt sees what others have missed. The burn patterns are wrong. The chemical residue is too precise. Someone made murder look like an accident. When ATF Agent Jonah Briggs arrives with his K9 partner, Sig, Cassian's controlled forensic methods collide with Jonah's field instincts.
Their approaches could not be more different, but the evidence keeps driving them together: a false paper trail, a shelter fire local authorities would rather forget, and a pattern of arson that points toward a ruthless campaign hidden inside a quiet Appalachian community. The closer Cassian and Jonah get to the truth, the more dangerous the investigation becomes. Each fire strips away another layer of silence, and each moment of shared risk turns professional friction into a connection neither man expected.
To stop the next blaze, they will have to trust the evidence, trust each other, and face a killer who understands exactly how fear spreads.
