Trish Van Devere plays a television executive (evidently inspired by Faye Dunaway in Network) in the made-for-TV Make Me a Perfect Murder. Denied a promotion, Ms. Van Devere retaliates by "cancelling" her boss--permanently. Utilizing her knowledge of TV mysteries, she manages to misdirect the trail of evidence. But Lt. Columbo (Peter Falk) isn't quite as gullible as your average TV fan. Make Me a Perfect Murder was the February 25, 1978 installment of the ongoing Columbo series.
