I'm currently reading Demise in Denim by Duffy Brown. This book is the fourth in the series and follows what I consider book 3.5, the short story e-book only, Dead Man Walker.
Demise in Denim takes over right where Dead Man Walker left off, with Boone on the run, the prime suspect of a murder, and Reagan reeling from his kiss. Conway Adkins, the newly murdered lawyer, had plenty of enemies and Reagan is determined to find the real killer. She manages, however, to find herself in more than one tight spot, with the "help" of Aunt KiKi, Chantilly, and Mercedes. Will she be able to figure out what's really going on? Or will she die trying?
