Bully

S12 E18: When an art patron, Cindi (guest star Countess LuAnn de Lesseps), discovers a gruesome work of art, it leads gallery visitors to find a woman dead in her apartment above. Detectives Benson (Mariska Hargitay) and Stabler (Christopher Meloni) look into the victim’s personal contacts in search of suspects, including the victim’s close friend Annette Cole (guest star Kate Burton). The detectives soon discover a work environment that leads them to question if bullying does go beyond the playground.
