In “Lovely But Lethal,” Vera Miles is Viveca Scott, a cosmetics magnate who needs a miracle product to keep her company from going under. When researcher Martin Sheen is discovered taking the formula to the competition, she murders him with the most deadly weapon known to mankind – a microscope. Throw in an alkie chemist, some Vincent Price, a little Bruce Kirby and oh, hey, another killing (this time, by poisoned cigarette) and no amount of foundation can cover up the blemishes of subterfuge and murder. Maybe Columbo’s some sort of cold cream of justice? Sure, let’s go with that. Elle Collins (Into It) helps Jon and RJ sort the whole thing out.
