An accomplished Columbo adventure with a well-written script that shrewdly fine-tunes the basic, well-established Columbo formula.
Donald Pleasence is magnificent as a wine fanatic who is horrified to learn that his impetuous and irresponsible brother (Gary Conway) is planning to sell off the family-owned vineyard. The sequence of increasingly antagonistic banter between the brothers, prior to the murder set-up, is powerful and ingenious. Pleasence renders Conway unconscious in a fit of rage in his office - does he immediately think of making it into a murder or does it become a gradual thought? In any case, the "eventual" murder is resourcefully constructed to be made to look like an accident; better than any other "made to look like an accident" scenario in the series.
Whilst there is not the typical plethora of circumstantial clues, the ones that are included are nicely inserted to achieve a decent impact.
The script-writer intriguingly develops the relationship between detective and murderer, as a mutual respect becomes apparent, especially as Columbo starts demonstrating his new-found knowledge on the subject of wine. Without contradicting myself, this is a remarkably positive element to the whole proceedings, given that my usual personal preference is for the Columbo-villain relationship to be more fractious.
Several later scenes uphold the high standard of the episode, primarily, when the murderer's grip over his secretary is "turned on it's head"; in the restaurant, when the murderer ironically complains about the over-heated wine; at the beach cliff-top, when the murderer is forced to throw away all of his wine from the cellar etc.
There is hardly a dull moment in this Columbo adventure; the pacing of the story is not frenetic, rather it is all executed in a calm, controlled manner which is symbolic of its subtleties.
It is one of Peter Falk's favourite episodes and one of mine - highly recommended viewing and an episode that would be great for newcomers to the series (if there are any) to watch, in order to endear themselves to the Columbo character.
