Agreed. Calvert was very harsh in his delivery of just about anything. I always get a laugh when he says to Colombo regarding his cigars "you gnaw on it like a beaver"
Yes I think Clifford goes to jail 1 time to visit Kathleen but that's it. Drop off the divorce papers and then on with his life. But he is so arrogant, that he's going to look for some other partner that he can boss around and wear the pants in the relationship so to speak. I doubt that Kathleen Calvert ever brought in any money into that relationship. Needless to say, Clifford is set money-wise.
