Nearing the end of a successful career, Minneapolis homicide detective Dan Neumann was looking forward to retirement and a relaxing summer riding his Harley, woodworking, and writing another textbook on ballistics. But Neumann's leisure plans go up in smoke when law enforcement calls on his expertise to investigate a murder involving a weapon so sophisticated, so lethal, it's never been seen before. Realizing he is up against intelligence and formidable skills equal to his own, Dan pursues the Shooter around the country, determined to crack his last case. Always one step behind the killer, Dan follows an ever-bloodier trail from Alaska to Arizona, murder to murder, enlisting the help of a particularly interesting deputy sheriff along the way. The chase leads to the shores of Lake Superior, whisper-close to the murderer. But is it close enough? And where is the "real justice"?
