(1973)
Dr. Bart Keppel has a very high opinion of himself, but, notwithstanding his opinion, he is being fired by Vic Norris. So he decides to plan a murder, a perfect alibi for himself and evidence against Mrs. Norris. He kills Vic while running commentary on a promotional short film. But there are bound to be some failures, even in the most perfect planning. And you can be sure that Lt. Columbo will find out these failures. Written by Baldinotto da Pistoia
