While taking her afternoon off, Rose (Jean Marsh) offers to deliver a cake to a friend. En route by bus, she accidentally bumps into Gregory Wilmot (Keith Barron), a young Australian sheep farmer. Though the cake is ruined, a romance blossoms between Rose and Gregory -- much to the bewilderment and dismay of the Eaton Place household staff. Written by Jeremy Paul, "A Perfect Stranger" made its British TV debut on January 5, 1974, and was first seen in America a little over one year later, on January 12, 1975. ~ Hal Erickson, Rovi
