A Stitch in Crime
Russian title: Звено в преступлении · Russian version
A heart surgeon murders his own research partner in the middle of an operation, using dissolving suture on a man he has just repaired. Leonard Nimoy plays him as pure clinical intelligence, and it is the coldest murder in the series.

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
Dr Barry Mayfield and Dr Edmund Hidemann have developed a heart drug together, and the credit — and the money — is about to be published under both names. Hidemann has discovered that Mayfield falsified data, and intends to withdraw the paper and expose him.
Mayfield's answer is the most audacious in the run. Operating on Hidemann himself, he closes an incision using suture designed to dissolve, so that his partner's heart will fail days later, at home, in front of witnesses, with no surgeon anywhere near him. It is a murder committed inside a hospital with a room full of medical staff watching and seeing nothing.
When a nurse notices the wrong material on the tray, he kills her with a tyre iron and stages a mugging. The contrast is the point: the doctor's murder is invisible, and the ordinary one he has to improvise is brutal and clumsy.

How Columbo gets him
Mayfield never once pretends to respect Columbo, and the film is better for it. Where most murderers perform charm, he performs impatience — the surgeon's certainty that anyone outside medicine is functionally a child. His answers are technically true and designed to end conversations.
The lieutenant's advantage is that he does not need to understand cardiology; he needs to understand people. He notices that the nurse's death is too convenient, that Mayfield's account of the operation is complete in a way that accounts of operations are not, and that a man who is furious about being questioned is a man who expects to be questioned.
The tension in the last act is unusual for the series: Hidemann is still alive, in a hospital bed, dying on a schedule his partner set. Columbo is not just proving a murder, he is trying to stop one that is still in progress.

Worth knowing
- Leonard Nimoy filmed this between Star Trek and Mission: Impossible, and later called Mayfield one of the least sympathetic characters he ever played.
- The medical procedure was staged with consultants, and Nimoy learned the movements well enough that the surgical scenes hold up.
- Anne Francis plays the nurse whose attention to detail kills her — a small role that the episode treats with unusual seriousness.

Verdict
The best episode of the second season and one of the top handful overall. The murder method is the cleverest the series devised, and Nimoy gives the show its most genuinely chilling villain: a man who kills the way he operates, without emotion and without hesitation.
It is also the rare Columbo where the stakes are live. Most films begin after everything has already happened; this one has a clock running through it.

What the people who made it said
Nimoy was under contract to Universal without a series of his own and was wary of being stuck in guest villain parts. Columbo, though, he did not turn down.
“I told Sid Sheinberg that I didn't mind doing a Columbo, but I didn't want to come out of the studio as the killer of the year. I had a great time working with Peter Falk. I found him a challenging and delicious actor to work with.”
