South of Sunset is an American TV detective series, starring musician/actor Glenn Frey, that only aired one episode on CBS in 1993. Frey played Cody McMahon, a private eye whose offices were located just south of Sunset Boulevard in Beverly Hills. As a result, he calls his business the Beverly Hills Detective Agency, despite the fact he's in the "low-end" part of town. Aries Spears co-starred as Cody's young assistant Ziggy Duane, and Maria Pitillo played his cute blond secretary Gina Weston. The show was a combination of comedy and suspense, reminiscent of ABC's hit series Moonlighting. The show was created by John Byrum, who wrote all six of the episodes that were produced, and served as co-executive producer with Stan Rogow. The show was heavily promoted during the 1993 World Series by CBS. However, only the pilot of South of Sunset ever aired, on October 27, 1993—and not even to the entire country. News coverage of wild fires in Malibu pre-empted the show's lone episode on many West Coast stations, including KCBS in Los Angeles itself. Disappointed with the ratings of the pilot and unwilling to give it a chance to build a base, CBS immediately cancelled the show, much to Frey's chagrin. VH1 later aired four more of the shows as part of their Eagles Family Tree Week.
