Just one little thingy Joe...Ric was already dead when Adrian had to put the wet suit on him.
But I totally agree. Adrian Carsini was not exactly in the greatest physical shape and it is far-fetched to believe he could have done all of this physical stuff.....and on top of it, ride back on a bicycle!!
I personally place more value on the plots and clues. The verbal debates are an important aspect, and I enjoy them greatly, but they have to be grounded in some substance. They have to lead to a satisfying conclusion or development in the case.
It's certainly nice to see that others are starting to come around to my way of thinking: "Any Old Port In A Storm" is not a very good episode of "Columbo".
