Peeples' TV roles have been prolific, due in part to the fact that many of her series commitments have been short-lived. In 1995, she had a regular role as a driven and dedicated public defender on CBS' "Courthouse" which suffered an early demise just as the same network's medical drama "Crisis Center" two years later. Peeples has stayed busy and in the public eye with frequent TV-movie appearances and guest starring series roles in projects as varied as "Swimsuit" (ABC, 1989), "Nasty Boys" (NBC, 1989-90, as Benjamin Bratt's pregnant wife), "Return to Lonesome Dove" (CBS, 1993, essaying a female gunslinger) and "Mr. Stitch" (Sci-Fi Channel, 1996, playing a psychiatrist treating a Frankenstein-like monster). The actress returned to regular series work in 1999, joining the cast of the hit CBS drama "Walker, Texas Ranger", playing Sydney Cook, a daring undercover officer skilled in martial arts.
While best known for her television work, Peeples has appeared in a handful of features since her debut in the Hawaii-set romance "North Shore", including the sci-fi adventure "DeepStar Six" (1989), the independent thriller "Improper Conduct" (1994). Additionally, she starred opposite Jason Alexander in the poignant romantic comedy "I Don't Buy Kisses Anymore" (1992). She then portrayed an appealing but tough Los Angeles police officer in the lackluster 1998 sequel "Blues Brothers 2000" and then played the opposite side of the law as a trained mercernary in the in the action crime feature "Half Past Dead" (2002), which starred Steven Seagal. A talented singer as well as actress, Peeples excelled in roles that made use of her vocals, from "Fame" to "I Don't Buy Kisses Anymore", where she contributed three traditional Italian songs to the soundtrack. Before pursuing an acting career, She was a featured member of 'The Young Americans' song troupe. The group frequently guested with Liberace, and Peeples earned an early TV credit in this capacity, performing on the famed pianist's cable-aired 1980 holiday special. Her singing also landed her on European television, as one of the stars of the 13-episode series "Music Shoppe", playing a young aspiring singer. Music again took center stage in Peeples' career in 1988, with the release of her debut album "Nothin' But Trouble" which spawned the dance hit single "Trouble". She followed up with the less successful 1992 self-titled release, emerging with a new more sophisticated look that distanced herself from her days, but failed to live up to her first release. Instead, Peeples has been able to reach a much larger audience through her acting pursuits.
