In Hillsford, California, a sadistic killer stalks the streets—his methods brutal, his targets chosen with unnerving precision. Businessmen are strung up as warnings, neighbors beheaded, commuters set ablaze in public spaces. The killer appears to be a chameleon in the way he dresses and performs each kill differently. To the city, he is a monster. To himself, he is a vigilante, cleansing the world of those who prey on the vulnerable. And he’s just getting started.

Detective Alma Rossi has seen plenty of blood in her career, but nothing like this. Devout, disciplined, and sharp-eyed, she knows every detail tells a story—yet the “Chameleon Killer” leaves no pattern, no trace, only horror. Each death pushes him closer, not just to Alma’s investigation, but to Alma herself. When her dog and best friend are taken as leverage, the case stops being professional. It becomes personal.
