From Ellery Queen stories:

***

"[You couldn't expect someone to believe] that a man dead one hundred and thirty-seven years could push aside his tombstone, step out of his grave, yawn, and then sing three verses of /Mademoiselle from Armentières/."

[Nor, indeed, has this happened, even in the story. It is simply Ellery's idea of a hypothetical example!]

***

"We'll find her where the cummerbunds are thickest."

***

"Paula, your Hollywood is driving me c-double-o-ditto!"

***

"Now what kind of clean-up... was this monkey figuring on?" asked Inspector Moley quietly. "And if that's not something, Mr. Queen, I'm the monkey's uncle!"

[This may be the most specific monkey I've ever seen benuncled--I mean, usually one is just "a" monkey's uncle, right? By the way, Inspector Moley also, on one occasion, says not simply "Nuts!" but "Nuts and bolts!" to more comprehensively vent his frustration.]

***

[One from Ellerys' own mouth.]

"You're nursing a viper to your collective bosoms, Miss Godfrey. And that's not as funny as it sounds."

***

[And I certainly wasn't expecting an oblique reference to an old Wilde anecdote! (Rest assured that no one in the book is actually called Oscar.)]

"Then she'll be looking--"
"She has, Oscar, she has," said Ellery mildly.

***

He found Paula finishing an apple and looking lovely, serene, and reproachful.

From a novel by "Barnaby Ross," which is an alternate pseudonym for "Ellery Queen":

Dromio, whose pride of profession approached the sublime, drove Mr. Lane's glittering limousine with the finesse of a Philadelphia lawyer and the facility of a première danseuse.
