A routine medical procedure triggers a series of vivid, haunting memories that force retired detective J. P. Beaumont to confront cold cases from his past. While recovering from knee-replacement surgery, Beaumont experiences drug-induced dreams that bridge his time in Vietnam and his early career with the Seattle Police Department. These fragmented recollections soon manifest as tangible threats when he realizes that unresolved crimes from his history are linked to a string of present-day murders. Beaumont must navigate his own compromised physical state and the blurred lines between memory and reality to prevent further violence. The narrative employs a dual-timeline structure, alternating between Beaumont's current investigation and his formative experiences in the military and law enforcement.

This novel is characterized by its focus on the internal development of a long-running series protagonist. The narrative structure suggests a deliberate attempt to deepen the reader's understanding of Beaumont's history by contrasting his current vulnerability with his past experiences. The pacing is dictated by the protagonist's recovery, creating a methodical investigation that relies heavily on memory and psychological tension. The genre conventions point to a procedural that prioritizes character growth alongside the resolution of a complex, multi-layered mystery.
