Corpse and Robbers (1973)

Corpse and Robbers was the first episode of the 90-minute TV detective series The Snoop Sisters. Helen Hayes and Mildred Natwick play Ernesta and "G." Snoop, venerable sibling mystery writers. In the manner of Murder She Wrote's Jessica Fletcher (whose own show wouldn't premiere for another decade), the Snoop girls solve mysteries as well as write them. In this inaugural episode, the ladies are plagued by phone calls from an old friend--who died several years earlier. Sam Jaffe and Geraldine Page head the guest star cast of Corpse and Robbers, which was first seen December 19, 1973. ~ Hal Erickson, Rovi
