Did You Know?


This is one of the few Columbo episodes where the original murder is a spontaneous act. In most episodes the murder is carefully planned. See more »


As Columbo questions Nadia one day after the murder, he lights his cigar with Dr. Collier's lighter. He then holds his cigar and his notebook in his right hand. As Dr. Collier crosses from the sofa to a chair, Columbo transfers his notebook to his left hand, at which point his cigar completely disappears. See more »


Man doctor at party: You know, I find this absolutely fascinating. Do you have, uh, an interesting investigation you've been involved with? We'd love to hear about something like that.
Second man doctor at party: Yeah!
Woman Doctor at Party: Yeah!
Columbo: I think that the most interesting investigation is always the one that you're working on at the moment.

George Hamilton is a Svengali-like psychiatrist in this weak "Columbo"
29 January 2007 | by (United States) – See all my reviews

Things aren't going well for Dr. Mark Collier (George Hamilton), a psychiatrist who specializes in hypnosis. He's stealing drugs from his clinic to use in an experiment with his disturbed patient, Nadia Donner (Lesley Ann Warren), but he's not getting the results he wants. Nor is he getting them from the lab experiments conducted by his harried research assistant (Karen Mochon). It seems his book, which is dependent on these results, will fail. Far worse, he's having an affair with Mrs. Donner - and Mr. Donner (Stephen Elliot) finds out. The husband confronts these two illicit lovers at his beach house, but in an angry moment Dr. Collier kills him with a fireplace poker. Collier convinces Mrs. Donner to lie to the police and claim that two intruders killed her husband. But can she convince the rumpled, redoubtable Lt. Columbo (Peter Falk) that she's telling the truth?

This episode has almost no extraneous comic business, which at first makes it seem sharper than many others made around this time. Hamilton and Warren give particularly strong performances. But the circumstances of the second murder (which I won't reveal) are difficult to believe; and the ending is flat. "Columbo" fans will enjoy it somewhat, but the average viewer will be sorry he wasted his time.
