I love 1970s police and detective shows. However, one shortcoming they have is that sometimes you see the same actors playing baddies again and again...to the point where you automatically assume they are the villains when you see them! In the case of "Triangle of Terror", you see both Don Knight AND Lloyd Bochner and assume they are evil...so it's a case of two for the price of one!
This show is a major change of pace as Cannon is hired to go to a Caribbean island and help solve a case. A seemingly rich and well respected member of the community appears to have killed himself after embezzling some money. But why would he need the money OR kill himself?! This doesn't make any sense and the trail leads to some lost Cuban gold, tales of the Bermuda Triangle and greed.
I love the change of pace and seeing Cannon hanging out in paradise is quite nice. Well worth seeing.
