Lynda La Plante (born Lynda Titchmarsh) is a British author, screenwriter, and erstwhile actress (her performances in Rentaghost and other programmes were under her stage name of Lynda Marchal), best known for writing the Prime Suspect television crime series.
Her first TV series as a scriptwriter was the six part robbery series Widows, in 1983, in which the widows of four armed robbers carry out a heist planned by their deceased husbands.
In 1991 ITV released Prime Suspect which has now run to seven series and stars Helen Mirren as DCI Jane Tennison. (In the United States Prime Suspect airs on PBS as part of the anthology program Mystery!) In 1993 La Plante won an Edgar Award from the Mystery Writers of America for her work on the series. In 1992 she wrote at TV movie called Seekers, starring Brenda Fricker and Josette Simon, produced by Sarah Lawson.
She formed her own television production company, La Plante Productions, in 1994 and as La Plante Productions she wrote and produced the sequel to Widows, the equally gutsy She's Out (ITV, 1995). The name "La Plante" comes from her marriage to writer Richard La Plante, author of the book Mantis and Hog Fever. La Plante divorced Lynda in the early 1990s.
