Sabra, if you recall in the episode when Columbo visits the guy atthe country club, and he states "I think we were being followed. Although I never really saw anyone, there was this one guy...crew cut, ex-marine type."
Now one of Brimmer's "goons" phones him from the car phone and tells him that Columbo and the golf instructor (whose name eludes me, BRAIN DAMAGE), are together talking, that's when Brimmer calls Leo and sends him off on that special assignment. I think Brimmer did that so Columbo wouldn't be able to speak to Leo about the fact he was tailing Mrs. Kinnecutt.
I wonder if Leo is still on that special assignment? Wouldn't you be ticked off if you got sent to the far end of the earth and your company went under with the arrest of the CEO? I hope he had airfare home?
Talking about disposing of the corpus delecti I always thought Edddie Albert was taking a big risk with the body being hidden in the wall of his house ("Dead Weight").
By the way, I think I saw on "Mythbusters" that a potato in a car exhaust will not immobolise it. Is that true? Anybody tried it?
