First telecast December 16, 1972, The Snoop Sisters was the pilot for a Richard Levinson/William Link detective series. Helen Hayes and Mildred Natwick play a couple of mystery writers who happen to be siblings. With the help of their pragmatic chauffeur (Art Carney), the Snoop Sisters take it upon themselves to solve real-life mysteries. In this instance, the ladies try to uncover the truth behind the murder of reclusive film star Paulette Goddard. The highlights of The Snoop Sisters include a slapstick car chase and an extended vignette from Ms. Goddard's 1940 feature film The Ghost Breakers. Also worth noting is the early supporting-cast appearance by Jill Clayburgh. When packaged for local syndication, The Snoop Sisters was retitled Female Instinct. ~ Hal Erickson, All Movie Guide
