William Conrad performs with some cute kids--and the show manages to be entertaining and among the better episodes of season one.
7 June 2013 | by (Bradenton, Florida) – See all my reviews

I never realized that the annoying character, Dodie*, from "My Three Sons" was played by Leif Garrett's sister. I guess not knowing this isn't surprising, as her stage name is Dawn Lyn (they both didn't use their real last name, Nervik, which isn't really surprising). Still, this is an unusual chance to see the pair of actors acting together as siblings! Truly a case of art imitating life.

A millionaire offers Cannon a case--one that sounds way too simple. He's to surreptitiously accompany his daughter and her kids on a train ride and just keep an eye on them! Odd--especially since the guy gives no indication that the family was at risk! During the train ride, Cannon uses an interesting tactic--instead of observing them covertly, he ingratiates himself to the children and becomes a sort of family friend. All goes well and the trip is complete. However, as an added part of the job, he checks up on them after the trip--and finds the woman dead and the kids gone!! The only clue he has are some fake bonds that she had passes on to him in a present--a way to try to get help--which ended up being too late. What gives?! Who is responsible for the murders and where are the kids?

"Death is a Double-Cross" is a show that shows a softer side of Cannon--something I enjoyed very much. You like the kids and it hits you like a brick when they are abducted--and you can see that he, too, really likes them and wants to help. But it also has a very nifty plot, a satisfying ending and it's a case where guest starring some kids does NOT slow down the plot (this sometimes happens when you have cute kids on shows). Well worth seeing--and among the better shows of season one.

By the way, I really liked the 'How do you figure on lifting me' scene--and I was impressed by Conrad's fighting skills (he did a great job for such a rotund guy). You have to see it to appreciate it! * I don't wish Miss Nervik any ill. Dodie was a poorly written character and you can't blame a kid for this (she was getting well paid for playing this regular character but the show clearly jumped the shark with her character)! She probably is a very nice person and I wish her well.
