S13, E19: An attractive young woman is found bludgeoned to death in an alley in Soho. She was dressed very provocatively and her address book is smudged from sitting in a puddle all night. The cops finally get an ID - she's Rachel Cardwell, who works for a top of the line graphic design firm. Briscoe (Jerry Orbach) and Green (Jesse L. Martin) search her apartment and are met by the man across the hall, Tim Grayson (Robert Stanton). He's rather nerdy but he claims to be friendly with Rachel. He said he saw her the night before when he was coming upstairs from the laundry room and didn't like the way she was dressed. The only evidence at the scene is a usable footprint and the detectives retrace Rachel's last night. There is a message on her machine from her friend Leanne Parks (Robin Weigert) who obviously had a good time - they were at a special, upscale club called Tart for professional women who must be members.
