A Man Called Sloane (original airdate: October 13th, 1979) is a pretty good one. "Masquerade of Terror" begins when Jeremy Mason (veteran heavy Richard Lynch), a master of disguise and old enemy of T.R. Sloane's, escapes from prison. KARTEL hires him to impersonate a U.S. general in order to steal a top secret laser satellite system known as Seeker.
UNIT's only lead to Mason is a nightclub dancer he's obsessed with named Linda Daniels (LaVelda Fann).
Sloane and Torque keep her under watch, waiting for Mason to make
contact, but they don't have to wait long before Mason, in disguise,
kidnaps her right from under their noses.
has two intertwining plots: Mason wants revenge on Sloane for putting
him away, and KARTEL wants to use Seeker to assassinate a visiting
African dignitary. Actually, the realization of the Seeker satellite
weapon is pretty cool. Unlike the laser satellites seen in Diamonds Are Forever or Real Genius,
the Seeker homes in on its targets with small targeting discs. These
discs have to be physically placed on or within the designated targets, but it makes it
impossible for the orbiting weapon to miss.
Richard Lynch is awesomely evil as usual, and makes a very formidable foil for Sloane. His ability to whip up Mission: Impossible-styled
disguises using only standard make-up is unbelievable, but it's a
classic spy-fi trope. LaVelda (as she is billed in this episode) is a
lovely woman and has genuine chemistry with Conrad. She dances great,
This one's a lot of fun, and probably the best in the series so far.
Lavelda is Robert Conrad's wife, and according to her IMDb page, she
has pretty much only acted in her husband's productions, including guest
roles on The Duke, High Sierra Search & Rescue and the TV movie Sworn to Vengeance.
