Columbo is an inverted mystery: the murder opens the film and the killer is known from the first minutes. What you are watching for is how he proves it — see how the character works.

The murder
Bart Keppel makes corporate motivation films and understands, professionally, how to make an audience want something without knowing why. His client Victor Norris is about to expose him over blackmail, in front of an audience, at a screening Keppel himself is running.
So Keppel builds the murder into the film. He splices single frames of ice-cold drinks and salted food into the reel, so that at the calculated moment Norris — thirsty, unaware why — leaves the auditorium for the lobby bar, where Keppel is waiting for him.
He shoots him there, returns to the projection booth, and is back in the room before the film ends. The alibi is not a lie about where he was; it is a piece of engineering that put the victim exactly where the killer needed him.
Bart Keppel makes corporate motivation films and understands professionally how to make an audience want something without knowing why. He has also been blackmailing his client, and the client has had enough.
Victor Norris intends to expose him at a screening — in front of the people whose opinion matters to Keppel's business. The venue is Keppel's own, which is his opportunity.

The alibi is not a lie about where the killer was; it is engineering that put the victim where he needed him.

How Columbo gets him
Culp's Keppel is the most likeable of his three: a salesman who genuinely enjoys explaining his craft. When Columbo asks how subliminal advertising works, Keppel demonstrates — twice — because a man who spends his life persuading people cannot resist a curious audience.
The lieutenant's first problem is the timing. Norris left a screening he had every reason to stay in, at the one moment his killer had cover. Coincidence is possible. Coincidence that convenient is not.
The route to proof runs through the film itself. If frames were added, frames exist; if a projectionist handled the reel, he saw something; and if the murderer edited under pressure, he made the kind of small error that only shows at twenty-four frames a second.

Worth knowing
- The subliminal advertising premise was topical in the 1970s and is treated here as more effective than it actually is; the episode is science fiction with a stopwatch.
- Culp's three murderers all share a trait: they are professionals who explain their expertise to a policeman they consider harmless.
- The final trap is the only time in the series that Columbo commits a small crime of his own to catch someone.
- The subliminal advertising premise was topical in the 1970s and is considerably more effective here than the technique is in reality.
- The final trap is the only occasion in the series where Columbo commits a small crime of his own to catch someone.
- Broadcast in December 1973; Culp's third and last turn as the murderer.
Verdict
The most inventive murder method of the middle years, and the best use the series ever made of Culp. Keppel is charming right up to the moment he is not.
It is also the neatest example of the show's favourite structure: the killer's own trick, turned around and used on him.

What the people who made it said
Cannell wrote the villain without naming an actor to anyone. The part went to Robert Culp anyway — his third killer in the series.
“Robert Culp was exactly the guy I pictured. But I never said to anyone, 'Gee, Robert Culp would be perfect for this.'”
