The greatest detective series in history comes to an end with a fine send-off. What made many (though certainly not all) of the later Columbos disappointing relative to the early ones were a) the turning of Columbo into a caricature - making himself look dumb and comical, and explaining everything five times as if speaking to a two-year old; b) excessive tampering with the tried and true Columbo formula; c) poor writing, with far fewer of the subtle and comic quotes, less successful humor, and wasted stretches with silly chatter or events that have nothing to do with the main plot. Well, this last episode does not have much humor, nor some of the great dialogue between the murderer and Columbo that many of the great episodes had. But it makes up for it by providing a ton of real sleuthing by the master, as he solves the puzzles by noticing the types of things only he would notice, and brilliantly tying it all together. It is a tight and well-written screenplay, with Columbo getting right down to business from the moment he first arrives on the scene until the very end, with the only sideshow being a minor, well done and humorous mafia subplot. After quickly identifying that it is a murder, not a suicide, and finding the suspect through astute observation and a neat detective trick, he sets out to trap the killers - not by acting like a semi-senile old man, but simply by acting naive and acceptive of their explanations - so that they say things they might not have volunteered otherwise - while at the same time dropping subtle hints to make them scared and confused. And while the music and scenery is updated to fit the modernizing times, he stays true to his character throughout. Other than one or two far-fetched things he does in finding clues (like sticking his hands into a toilet bowl), the plots and clues, and the manner in which he solves them, are quite believable. Not one of the very best episodes, but still a highly enjoyable one that honors the series and has very few uneasy or boring moments.
