A serial killer who leaves a roadmap on his victims should be easy to track down…

When Carly is roused in the middle of the night to come to work she knows she’ll be heading for a murder scene. After all, she’s a homicide detective, it’s her job, and she’s prepared for everything. Until she arrives in a suburban commuter parking lot where a young lawyer is lying on the ground, a hole in his chest, his organs vaporized, and a topographic map of a metropolitan grid tattooed on his face. A week later victim number two—same first name, same fist-sized hole in his chest, his organs vaporized and wearing another topographic map on his face—points to something more sinister that could lead to a nearby army facility.
