Inheriting a country house from an uncle she never knew she had, Emma shows up at her new lodgings, only to find out that she has been lured into a trap. The instigator of this outrage is an old enemy of our heroine, an electronics genius with a gift for deadly inventions. As Emma eludes one elaborate death trap after another, Steed races to the rescue, though he may not arrive in time to prevent the poor girl from going off her trolley. A typically gimmick-laden Brian Clemens concoction, “The House That Jack Built” made its American network TV bow on May 16, 1966.
