In the perpetually bustling metropolis known as The Outside, where crime has spiraled beyond the capacity of official law enforcement, unlicensed investigators called fixers operate in the shadows, handling cases the police cannot or will not pursue themselves. Neil Fox, a former detective turned fixer, possesses an uncanny psychological ability to inhabit the mental state of criminals mid-crime, granting him insight into their motivations and methods that have cracked cases others abandoned. When a third sex worker is discovered murdered under mysterious circumstances, Fox is contracted to investigate, and his unique talent reveals a chilling pattern: the killer is systematically disguising each victim as someone else. As Fox traces the thread of this false identity, he uncovers a web of interconnected relationships and dark secrets that transform the case from a simple serial killing into something far more complex and sinister.
