Lillian Stanhope and Nicholas Frame are two famed actors in London, a venerated husband and wife team set to act in 'Macbeth'. Producer Sir Roger Haversham had been Lillian's lover but finds out he has been deceived by the couple and is ab out to cancel their widely anticipated and lucrative engagement. During a dressing room brawl between the three, Haversham is accidentally killed when he is hit in the head by a projectile thrown by Stanhope. As Haversham had not been seen by any of the cast or crew before he entered the couple's dressing room, the couple decide to hide his body and later take the corpse to his mansion and stage his "accidental" death. However, Lt. Columbo, in London to learn about new investigation methods used by Scotland Yard, smells something fishy in this supposed accident. Written by Baldinotto da Pistoia

Did You Know?


Inside joke: "Lillian Stanhope" (Honor Blackman) says "I've always wanted to be in a horror movie." 'Dagger of the Mind' aired on 11-26-72. Just six months earlier (5-30-72), the horror movie 'Fright" was released, which featured Honor Blackman. See more »


Lilian Stanhope addresses Columbo inconsistently, pronouncing his rank as 'Loo- tenant', the American way, and 'Left-tenant' the British way. An English actress of her standing in the 1970s would always use the British pronunciation. See more »

Columbo: When you said tea, I was afraid we were going to get nothing but those tiny sandwiches. This is terrific.
George, Steward at Supt. Durk's Club: Why do you think we keep the ladies out, sir?

Columbo matches wits with Scotland Yard
19 May 2006 | by (United States) – See all my reviews

In this Columbo episode, it features Honor Blackman (who denied a C.B.E.) and Richard Baseheart as an aging acting couple. The wife, Lilian Stanhope, played deliciously by Honor seduces a powerful older British gentleman to produce Macbeth for them to star in so they are not washed up like most actors and actresses in their predicament. Anyway, the plot is more like Macbeth and the film could be useful in an English class if you're teaching Shakespeare's Macbeth. Anyway, I have always enjoyed watching it from beginning to end. Let's not forget Wilfred Hyde-White who should have been knighted in the episode. Anyway, Columbo is a guest in their country and he becomes wrapped up in the investigation. While others have assumed it's just a robbery gone awry, Columbo always comes through. It's fun watching this delectable group of characters and props like an umbrella. It's great to see London location. I believe apart from the Mexican cruise that London was the only other place that Columbo got to travel too.
