Kristine Kathryn Rusch is not known to me personally, but I've admired her career for a while. She writes romance, sci-fi and mystery at an award winning caliber, and her list of credits is amazing. Take a look.
The current issue of EQMM has one of her stories, and I think it is the best PI story I've read in a while. It's called Mr. Alibi and concerns a female PI who is in a bar waiting for a no-show client when she's approached by a man who wants her to alibi him for the night before when he claims to have murdered his wife. At first she thinks he's just using a pick-up line or trying to be funny, but doubts creep in and what follows is a mix of false identities, scams, and Hollywood history.
It's an engrossing story and the legwork the PI goes through felt real. Overall, a great read.
