Three years after the original Columbo pilot "Prescription: Murder", the great man got another chance for immortality in this film. Of course, the rest is history as Columbo went on to become one of the greatest and best-loved TV characters ever.
This pilot sets a high standard (which wasn't always maintained, let's be honest) and has strong writing and characterisation, as well as showing some visual flair with slow fades, jump cuts and other effects.
Columbo here is the Lieutenant we will come to love, absent-minded, rambling, but with pin-sharp instincts and a deep sense of justice ("I couldn't have you convicted on false evidence" he says at one point. He wants to catch the criminal but he will do it fairly and properly). The performances of Peter Falk and Lee Grant are excellent.
Some reviewers have felt the suspect wouldn't be stupid enough to use the ransom money after being so smart in planning the crime and covering her tracks. I think the fact the money was going into a *Swiss* bank probably made her feel it was a risk worth taking - you can't get any information out of those guys, so no-one would know it was the ransom money. Besides, she really doesn't have a conscience.
