Mack Denver has settled-sort of.
With his chosen "family" around him and his flash temper mostly in check, he's trying to do the right thing while digging into a twisted case of city-wide corruption.
But this isn't just any case-it's tangled up with one run by his old mentor, Sergeant Tom Stein of Boston South PD. And it's about to get personal.
With a sharp-tongued librarian, a born-again newsman, and the ever-patient Wanda at his side, Mack follows a trail through Boston's underbelly-from snake dancers and shady fixers to a half-mad witness no one believes.
Oh, and then there's the "Killer in a Black Dress"-a headline-grabbing mystery woman who seems to have her sights set on Mack.
Smart, dark, and crackling with 1950s grit, Killer in a Black Dress is Mack's most dangerous ride yet-and maybe his last.
