One of the best episodes of Kojak I remember seeing when it was first out was this one concerning a widower father and his son played respectively by Joshua Bryant and Lee Harcourt Montgomery. When Bryant who said he was working late doesn't show up at all, young Montgomery goes down to Manhattan South and talks to the detectives. One Theo Kojak is intrigued by his story.
Even though it's not technically the 48 hours required for a missing person's report, Kojak has Stavros take one anyway. This is a person of regular habits who is always there for his kid. A little investigation shows that Bryant who is a small time attorney with a practice in real estate law manages some property for a man who is a notorious swindler and fugitive.
The swindler's bigtime criminal attorney John Hillerman is planning to doublecross his boss who is flying back to the states to give himself up and name some names. Bryant is being used essentially as a Judas Goat so the fugitive feels he's among friends and then they're to be killed.
Highlight of the episode is Lee Harcourt Montgomery. He comes across as a real kid as opposed to some Hollywood type kid. His performance is poignant and touching. It makes this one of the best Kojak episodes.
