The Case of the Glamorous Ghost

This episode of Perry Mason is a winner. Paul and Della get a lot of screen time and in the end it really pays off. The cue music also has a Bernard Herrmann "Psycho" vibe.

Jealous sister: You know about this glamorous ghost, this exhibitionist ... who made a naked spectacle of herself in the moonlight.
PM: I saw the pictures in the papers ...

Jealous: As for them being married, that’s what she says.

PD: What does this Douglas Hepner do?
Mr. Corbin (father of the defendant and her sister): Well, he’s able to get a lot of people to hate him. But aside from being a cheap, parasitical Don Juan, apparently nothing.
                       
Miss Granger: Among other things, his mother is why I’m not his wife.

Murder victim Douglas Hepner actually had a career field. He was a professional informer, out on ocean liners earning that 20-percent reward that the Customs Service would pay for tips on smugglers.
PD: He’d soft-soap his way into the confidence of lady tourists with more money than brains.
I don't know how the reward system works today. Here's a form you can fill out to alert the U.S. Immigration and Customs Enforcement agency about suspected illegal activity.

When Hepner's body was found in the park where the defendant was making a spectacle of herself, he had very little on his person. This is a clue to Perry.
PM: What have you got in your pockets, Paul?
PD: Just a bunch of junk.
PM: Put it all out on the table here.
...
PM: What've I proved? That there wasn't quite enough stuff in Hepner's pockets.

Burger and Mason get into it in the courtroom. Utterly!
PM: Objected to as argumentative, assuming a fact not in evidence, leading and suggestive, and utterly incompetent, irrelevant and immaterial.

The Mason-Keteers are in Perry's office for the wrap-up. Perry hands Paul a check.
PM: Your fee from the Corbin family.
PD: Hey, this is a small fortune. You haven’t made some mistake? This must be your fee.
Perry says the family was grateful for his extraordinary service and felt his work made the difference in the outcome of the case.
DS: Perry, isn’t there someone I could sue for the scratch on my finger when I found those diamonds in Eleanor’s face cream?
And Perry hands her a check.
PM: The Customs Service is paying you the 20 percent reward for finding the smuggled gems.
Della looks at her check and then at Paul’s, which she dismisses.
DS: Small change.
Come along, gentleman, I’ll buy the dinner. 
Paul, you can leave the tip.
