21. Under My Skin

Complete story — includes the ending

A man shoots two paramedics and steals their ambulance with patient Maggie Halpern inside. A man named Wallace Turk later admits the murders. Halpern is also murdered, and her body is eviscerated by Turk's partner. Halpern was an unwitting drug mule who had received what she thought was normal surgery in Brazil. Her surgeon, Turk's brother-in-law, planted heroin inside her, then vanished. Drug gang leader Janko Stepovic uses the offices of dentist Dr Marty Ward. Bell tells Janko that if he buys the heroin, the NYPD will go after him. However, if he can help find the heroin, it will not be in the hands of rival gangs. Janko sets up a sting, but is killed elsewhere. Ward eventually gives up and agrees to tell all, including the location of two other mules' bodies. Meanwhile, a manufacturer hires Alfredo Llamosa, Sherlock's recovery sponsor, to test a security system, but fires him after Alfredo points out its flaws. They also spread false claims that he was high again. As revenge, Alfredo starts stealing their cars. Considering Alfredo his friend, Sherlock steals cars while Alfredo has an alibi. As being a sponsor is incompatible with friendship, Sherlock fires Alfredo.
