Something Triumphantly American

I'm currently reading F. Scott Fitzgerald's unfinished novel, The Last Tycoon. Because it is unfinished, there are little gaps where the editors explain that Fitzgerald meant to come back to a certain point in the story and introduce a character or something important like that. One such gap, in my opinion, makes the story even more amusing in its absurdiuty--I can't imagine how Fitzgerald was going to work in this introduction:

[Stahr (my note: a producer, the protagonist) was to have received the Danish Prince Agge. who "wanted to learn about pictures from the beginning" and who was in the author's cast of characters as an "early Fascist."]
"Mr. Marcus calling from New York," said Miss Doolan.
"What do you mean?" demanded Stahr. "Why, I saw him here last night."
"Well, he's on the phone--it's a New York call and Miss Jacobs' voice. It's his office."
Stahr laughed.
"I'm seeing him at lunch," he said. "There's no aeroplane fast enough to take him there."
Miss Doolan returned to the phone. Stahr lingered to hear the outcome.
"It's all right," said Miss Doolan presently. "It was a mistake. Mr. Marcus called East this morning to tell them about the quake and the flood on the back lot, and it seems he asked them to ask you about it. It was a new secretary who didn't understand Mr. Marcus. I think she got mixed up."
"I think she did," said Stahr grimly.
Prince Agge did not undertand either of them, but, looking for the fabulous, he felt it was somethinng triumphantly American. Mr. Marcus, whose quarters could be seen across the way, had called his New York office to ask Stahr about the flood. The Prince imagined some intricate relationship without realizing that the transaction had taken place entirely within the once brilliant steel-trap mind of Mr. Marcus, which was intermittenly slipping.
