I join in saying definitely try Christa Faust - she is an award-winner and an excellent writer. I read Money Shot and couldn't put it down.

A lot of good suggestions -- I would add Tee Gerritsen, author of the Rizzoli & Isles series (also the bases for the TV series on TNT), Liza Gardner, Zoe Sharp, Laura Lippmann, Alafair Burke (daughter of James Lee Burke), Allison Brennan.
That should get you started <g>
Back in the 80s I enjoyed the novels of Liza Cody, who had two very hardboiled female protagonists, a PI named Anna Lee and Eva Wylie, who is impossible to categorize. She grew up as a feral street child and lived hand to mouth as a junkyard security guard and part-time professional wrestler. She also got into jams whenever she tried to break out of her isolation.
The Anna Lee stories were adapted for British television, but the lead role was seriously miscast.
Aw shucks, can I suggest mine? Absolution is a gritty crime thriller. A killer preys upon young women in New Orleans, where everyone has something to hide. Some of the darkest secrets reside in a parish church. NOPD detective Frank Renzi must battle racial tensions and religious controversy to catch the killer before he murders another woman and delivers his twisted version of Absolution.
