 Pembleton ( Andre Braugher ) and Bayliss ( Kyle Secor ) investigate the murder of Angela Frandina , who was found strangled in her bed clutching a note reading , " Ed did it " , although it proves to be a false lead . Their investigation leads the detectives to discover Angela had several strange boyfriends and worked at an S & M fashion store and a phone sex hotline . The two detectives visit the Eastern Shores Marketing Phone Sex operation where they speak with the manager , Ed . Ed tells them about a boyfriend of Angela 's named Chris Novoselic ( Dan Garrett ) who used to spend time with her at an S & M club called ' The Eve of Destruction ' on Fayette Street . Pembleton and Bayliss go to the Eve of Destruction to question Novoselic . During questioning , Bayliss gets angry and loses his cool with Novoselic slamming the leather @-@ clad , multi @-@ pierced freak against the wall telling him that if he doesn 't start giving them some answers , he is gonna slap some cuffs on him , take him downtown and knock him around ' whereby Novoselic responds by telling Bayliss , ' If you do that , I might have to kiss you ! ' . Pembleton calms Bayliss and they leave . While driving , Bayliss claims to be disgusted by the sexual taboos , but Pembleton insists everybody has a darker side and that until Bayliss recognizes his own , his virtues can never truly be tested . Pembleton and Bayliss return to the S & M fashion store and ask about leather belts with bead patterns matching the marks on Angela 's neck . Store owner Tanya ( Adrienne Shelly ) tells them Angela 's neighbor Jeremy ( Scott Nielson ) has a jacket with a matching belt . After an interrogation , Jeremy confesses to choking and accidentally killing Angela with the belt during quirky and violent ( but consensual ) sex . As a thank you for solving the case , Tanya brings Bayliss a leather jacket as gift , which he reluctantly accepts . That night , Bayliss visits Baltimore 's red light district wearing the jacket , as a way to test himself as Pembleton suggested . He is approached by a prostitute but rejects her , thus passing the test .
