The Dallas Cowboys demolished the Buffalo Bills, 52-17, and the broadcast was followed by the premiere of a new NBC drama, set in Baltimore, studying the work of the city’s homicide detectives. The series was called “Homicide: Life on the Street,” and it was based on a book by David Simon, then a Baltimore Sun reporter who had spent a year tagging along with the police department’s homicide squad. Post-Super Bowl premiere notwithstanding, “Homicide” was never a ratings success, but it stayed on the air for seven seasons, winning four Emmys and three Peabody Awards. The show’s fifth episode, “Three Men and Adena,” which first aired in March, was a stark, dramatic example of what made “Homicide” different from other cop shows. Pembleton and Bayliss prod, provoke and rage, but “Homicide” refuses to grant the audience the resolution they crave.
