The Singing Shooters — Geoffrey A. Feller

Following a suspension after closing the Mercury Man case, Detective-Sergeant Natalie Dvorak is back on the job with the Vermont State Police at full rank. Her latest case has Dvorak on the trail of brutal killers whose crime complicates Dvorak's own personal life, threatening someone she holds dear. A demo tape of songs containing racist lyrics proves to be a vital clue to the murderers' identity, suggesting they will fight to the death rather than surrender. To catch the Singing Shooters, Sergeant Dvorak seeks help from a hostile teenage girl and an old flame she once put in prison.
