The effervescent Patrick McGoohan plays a Columbo murderer for the third time (and does a directorial turn to boot), as he depicts the hitherto untouchable lawyer, Oscar Finch, whose past comes back to haunt him in the form a notorious racketeer, Frank Staplin, who threatens to expose a 21 year old scandal in which Finch bribed the District Attorney at the time, Paul Mackey (who is now running for Vice President) to discard vital evidence that would have had severe consequences for Staplin.
McGoohan's performance deservedly won him an Emmy - McGoohan encapsulates the "charm" of a Columbo villain effortlessly with a crisp, precise and purposeful portrayal, tinged with a mild eccentricity, ensuring that his scenes with Falk have a razor-sharp entertainment value.
The script-writer, Jeffrey Bloom, also ensures that the vital commodity of humour is inserted at several well-timed moments in this TV movie, and like the 1973 episode from the original Columbo series "Candiadate for Crime", Columbo's intrusions with key personnel become increasingly antagonising as the presidential campaign reaches it's climax.
Satisfying as a whole, the episode is really only guilty of losing some its initial zest and pace around its mid-section when some of the investigation becomes a little drawn-out as the discussion of the clues becomes deliberately selective and individualised.
The resolution is totally unexpected and it astounds the murderer and viewer in equal measure: a devilishly clever element to a largely solid, well-made adventure for Columbo, which is probably one of the most polished stories of Columbo's latter-day movies.
