Mother regales his two elderly aunts with the thrilling story of "The Great Great Britain Crime." It seems that a group of international criminals planned, Ocean's Eleven-style, to steal all Britain's great treasures simultaneously, using a phony missile attack on London as their cover. Only the two aunties are at all surprised when the villains are thwarted by Steed and Tara. Utilizing generous library footage from the unaired Avengers episode "The Great Great Britain Crime," "Homicide and Old Lace" first aired in America on March 17, 1969, and in England nine days later. The original episode, and its new "wraparound" segments, were written by series stalwart Malcolm Hulke. ~ Hal Erickson, Rovi
