Stanford Chemicals CEO David Buckner wants to sell the business, but he is overruled by several people: his wife Doris, company lawyer Everett Logan, and his nephew Roger, the lighthearted young genius whose late father founded the company. But he has a plan: he has uncovered some very embarassing and illegal past activities on the part of Roger. He demands that his nephew change his aunt Doris's mind about the sale, or he'll tell Doris about all the nasty things her precious Roger has done. But Roger is one step ahead of him, and initiates a plan to murder his uncle with dangerous explosives. Unfortunately for him, he didn't count on Lieutenant Columbo investigating Buckner's "car accident." The Lieutenant quickly suspects Roger, and puts together a web of evidence to trap the young scientist in his own lies. Written by

In the tramcar high above the valley, the cable car guide is lecturing Columbo on the safety of the tramway. When viewed arriving at the top platform Columbo is clearly visible but the guide is nowhere to be seen in the glass windowed car, and presumably there was no way to get off before the top. See more
Lieutenant, you take an inordinate length of time coming to the point.
