***SPOILERS*** It's when French restaurant owner Ogier Douvay's, Claude Dauphin, step brother Marius, Fracois Flamand, is found stabbed to death in the kitchen area of his restaurant the NYPD is called in to investigate. Admittedly Marius was a good for nothing leach who stuffed his face with food without paying for it and never did a days work in his entire life! But him being savagely murdered was a bit too much of a price even for Marius to pay.
With the NYPD checking out all the clues to Marius' murder it's Ogier who soon becomes the #1 suspect in that there's a missing and critical 20 minutes that he can't seem to explain or account for during the time when Marius was killed. We in the audience do know just who murdered Marius since we saw it within the first five minutes of the "Naked City" episode and it wasn't Ogier. It was in fact fellow Frenchman the Algerian born Moktir, Nico Minarods, who killed him in revenge for Marius slaying his father back in Algeria! But here's where things get interesting in that Moktir noticed Ogier sexy wife Medeleine,Denise Darcel, who's some 20 years younger then her husband and instead of checking out of the country and getting safely back to Algeria he decided to stay in New York City and romance her. This despite her already being married to her wimp of a husband Ogier whom she has nothing but contempt,not love, for!
****SPOILERS**** The cops lead by lover boy and overly sensitive-for the criminal element in the city- Let.Adam Flint, Paul Burke, who seems to have no time for his long suffering girlfriend aspiring actress Libby Kingston, played by Nancy Malone, do in fact end up cracking the somewhat puzzling murder case. That's with Moktia admitting his crime, without the cops once having to work him over, and then sent straight to Attica State prison without even as much as a trial. As for Ogier's missing 20 minutes it had nothing to do with his step brother Marius's murder but with an extra material affair that he was having with one of his waitresses Anglique, Chana Eden. Which instead of having his wife Madeleine mad at him had her gain a new found respect for Ogler for being the man, or ladies man, and great lover that he turned out to be!
