Martin Kane is a detective series from the very early days of TV with an odd premise - The part of Martin Kane is played by several actors who rotate through the duty like they are guest stars. I guess the idea of building up a physical presence as a character is new - After all, in radio there WAS no visible physical presence. This week Kane is played by William Gargan.
A woman comes to see Kane and ask him to investigate the death of a wealthy old gentleman, a retired inventor for whom she was his personal secretary and a major beneficiary of his will. She's thus a suspect and she wants the real killer caught. This is where the first wacky idea appears. Kane says that he read in the paper that the man was killed during a burglary in his home. The woman says - "That's what was for public consumption. In truth he was brutally murdered!".
Huh? - If you are killed during a burglary you are NOT brutally murdered? No harm, no foul?
So Kane is basically investigating in parallel with the police who don't act like he is in the way. The police even tell him that the "burglar" was in the house for three hours based on a clock being unplugged at 11PM that night, they assume by the intruder, and shots being fired and heard at about 2AM. Why would a burglar stay three hours and take nothing? So the investigation begins.
What is interesting in these early TV shows is that there are no commercials per se. Instead, about twice during the episode everybody convenes at the neighborhood tobacco shop where the only brand sold is the sponsor's brand. Also at regular intervals you can see Kane fill his pipe with the sponsor's brand of tobacco. This went on into the late 1950s in shows where the sponsored brand could be incorporated into the show.
