1948 film by Jacques de Baroncelli

Airy comedy of a man a woman and the lengths they'll go to for a really great apartment! Located in the center of Rome with amazing views both want it and strike the compromise of marrying each other platonically to get it. The woman still hopes for true love and the man agrees to step aside should that special someone come along but he is secretly smitten with her and surreptitiously makes her various suitors look like fools. All goes well until he comes up against Rosanno Brazzi and finds him a tough challenge to overcome.

A chauffeur for a corrupt CEO, and a few hours later, his boss himself, are killed by the industrialist's associate. But their ghosts remain on Earth, and they try to tell the millionaire's teenage son the identity of the killer.

A series of crimes is being perpetrated around a famous singer. Strangely, during each of the crimes, the artist's voice is heard humming his favorite song. Suspicions lead to a chase through a nocturnal Paris, ending in a disused theater where the assassin has lured his final victim.
