Another link gone to what now seems like a golden age of network TV. Along with many of its contemporary dramas and comedies, Colombo was well acted and, equally important, well written - more than can be said for most today's stuff. The art of writing seems to have finally faded out when "Everybody Loves Raymond" went off the air. Good actors can be let down by indifferent writing, as in "Hot in Cleveland".
RIP Peter Falk - a great character actor backed up by great writers.
