Courting Trouble by Lisa Scottoline (2003, Paperback, Reprint)

Anne Murphy is the redheaded rookie at the Philadelphia law firm of Rosato & Associates, and one morning she wakes up to front-page headlines proclaiming lawyer murdered -- above her own picture.

To find the killer, Anne's got to play dead -- if she wants to stay alive. Though she tries to go it alone, she quickly realizes she'll have to trust people she barely knows -- colleagues who hate her, a homicide squad that wants her out of the crime-fighting business, and a new love who inconveniently happens to be opposing counsel.

But her knack for courting trouble makes it almost impossible for Anne to play well with others, and an unexpected event places her in lethal jeopardy and leaves her with everything to lose -- including her life.
