This is one of the better "Columbo" episodes. Oskar Werner is excellent as Harold van Wyck. The company name is "Midas Electronics." The previous reviewer misspelled that. Van Wyck is an inventor ahead of his time. The gadgets portrayed are now everyday things so someone on the production staff did a bit of research in '74 when the episode was filmed. It was originally broadcast during the spring of '75. Van Wyck is a complex genius as the character shows. He clearly enjoys creating the new "inventions." But, he is no saint in that he does apparently like the ladies, and has several extra marital relationships going on. The acting is excellent from an excellent cast. Martha Scott as the mother-in-law is suitably nasty as the company owner out for profit over ideas. Gena Rowlands is, as usual, equally good. This episode of "Columbo" is a rarity. It is the only work done by Oskar Werner on American television.
