This caught the attention of the producers of Dallas, who were searching for an actress to play Katherine Wentworth, the scheming half-sister of Pamela Ewing and Cliff Barnes. She debuted on Dallas in the 1981–82 season and her role as Katherine continued, on and off, until 1987. In 1985, she returned for a cameo in that season's finale, where her character killed Bobby Ewing by running him over with a car, killing herself in the process. She made a brief, final appearance on the series in 1987.
