Meet the black men and women policing our meanest streets...LaVerne Dunlap: she infiltrated a drug gang and testified against them in court ... only to have the drug lords mark her for assassination.Dep. County Sheriff Winroe Reed: he ventured into America's "Homicide Capital" alone to apprehend a 6'9" homicidal crack dealer... a man so dangerous no other cops would accompany him.Chris Saffron: he worked the toughest drug gangs in Harlem, alone... even after his cover was blown.These are just a few of the courageous black heroes readers will meet in Hugh Holton's "The Thin Black Line."
