Steed suspects that something's amiss when one of his old friends, a wealthy businessman, is buried in an out-of-the-way Cornish village. Several other deceased millionaires have likewise chosen this burial site, and it just doesn't add up. Conducting an investigation, Steed and Gale uncover a conspiracy involving a supposedly worked-out tin mine. Written by Roger Marshall, "Mandrake" first aired in England on January 25, 1964, but it wasn't seen in America until March 27, 1991. ~ Hal Erickson, Rovi
