B*tch

S13, E15: Brad Osterhaus, a successful stockbroker who was very friendly with numerous women, is found dead in his upscale apartment. He fell down the stairs but the cause of death is a blow to the head. Briscoe (Jerry Orbach) and Green (Jesse L. Martin) discover he has multiple female friends, and had recently purchased three expensive pieces of lingerie. One was for a friend who is about to get married (she also has an airtight alibi); another is for Lindsay Tucker (Melissa Errico), a photographer with a young child. She considered herself Brad's true girlfriend (the other women were just dalliances) and she is very upset. Her alibi is she was at the office of world-renowned cosmetics maven Jackie Scott (Lucie Arnaz) at the time Brad was killed. The detectives question Jackie but she isn't much help. She's an empire unto herself and corroborates Lindsay's alibi. But when the detectives ask a few more questions about the people in Jackie's and Lindsay's lives, they discover Jackie is Lindsay's mother and both mother and daughter were sleeping with Brad.
