From Trouble in the Brasses, by Alisa Craig

From Death on a Dark Sea, by R. A. Bentley:

From the old BBC radio show Take It from Here:

***
“You were very lucky to get him in at the Royal Academy of Puppets and Marionettes.”
“Well, naturally I had to pull a few strings....”

***
“I won’t be able to keep my job if a baby comes along.”
“Oh, Eth, they’d never give your job to a baby.”

From The Tomb of the Honey Bee, by L. B. Hathaway

From Blotto, Twinks, and the Riddle of the Sphinx, by Simon Brett:

***
Mr. Crouptickle looked quizzical. Doing this gave him no problem. He was wearing the kind of pince-nez in which it was virtually impossible not to look quizzical.

From Death Stops the Frolic, by George Bellairs:

From Death of a Lady, by R. A. Bentley:

From Blotto, Twinks and the Intimate Revue, by Simon Brett:

***
[Airheaded toff Blotto compliments a woman on her looks]
"You're a real bellbuzzer with three veg and gravy."

***
"The cream of Scotland Yard are all clotted."

***
"Don't nit-pick noodles!"

***
He didn't think Araminta fffrench-Wyndeau looked very happy either. She was still as silent as the second and third fs in her surname.

[Btw, I note the one-upping theme here, as Brett outdoes the real British lexicon. First "with three veg" (as opposed to the more familiar two), and now a three-f fffrench.]

***
"Beauty, of course, is in the eye of the cigarette holder." [This is one of many defective witticisms uttered by a character who is supposedly "the wittiest man in London," and whose repertoire consists of broken Wildeisms, epigrams that begin like quips but end like boring, literal observations, and so on.]

***
"Lawkins!" said Twinks. And she meant it.

***
"Tickey-Tockey," said Twinks, though without the vim she usually put into a "Tickey-Tockey."
***

[Bonus: In sending up 1920s aristo types, as you may have gathered, Brett favors silly pseudo-slang that he's apparently coined himself over historically authentic slang. Here's my favorite from this book: giving someone the idiomatic cold shoulder becomes giving them "the ice cream's elbow."]

From Murder to Music, by Margaret Newman:

From I Should Say So! by James Montgomery Flagg:

From The Black Cat Murders, by Karen Baugh Menuhin:

From Jeeves and the Leap of Faith, by Ben Schott:

***
"I suppose there's a snag?"....
"Two, actually: Evadne and Lancelot."
"Eh?"
"Her Ma and Pa."
This sounded like one large, amalgamated snag, but Gussie informed me otherwise.

***
"We should strike while the whatnot is hot."

***
Jeeves permitted himself a riotous twitch of the eyebrow.

***
"Why don't you just make things up? I bet no one would twig if you invented a dowager duchess or two."

**
"I knew those cummerbunds were an incident waiting to happen."

**
"The garden looks like...a birthday cake!"

[The character who says this turns out to be Wittgenstein--and, according to Schott's endnotes (remember, his reputation rests on trivia, not fiction) a remark along those lines can actually be traced to real-life Wittgenstein's criticism of the grounds at Cambridge.]

***
A smile inched across Gussie's face, transforming it from lugubrious haddock to exuberant flat-fish.

***
"[I have] News. Pages of it. You might use me to wrap fish 'n' chips."

***
How Jeeves accomplishes his effortless omniscience is one of those eternal, unfathomable mysteries, like the Hanging Gardens of Babylon, or Percy Gorringe's side-whiskers--which, now I picture them, also hang pretty Babylonically.

***
He unleashed the italics.
"Sir?"

***
The emotions that swept across Aunt Agatha's face--shock, bafflement, fury, doubt--wove a Bayeux Tapestry of indignation.
***

[Bonus: "Toe over kettle" as an alternative to "head over heels" or "base over "apex." Googling suggests that this is a Schott original.]

[Bonus: When Bertie gives a fake name and address to a constable (as of course is traditional in the canon), it turns out in the endnotes that Schott has used a "real" fake address--namely, the street address of a real-life London facade that was built merely "to conceal a venting area of the Metropolitan Railway."]

From The Middle Temple Murder, by J. S. Fletcher:

***
He waited at a corner of it wondering what he was going to see, and intensely curious about the owner of the queer voice, with all its suggestions of he knew not what.

***
[Well, I Suppose It's an Improvement dept.]

***
[From the "Longest Distance Between Two Points" dept.]:

There are few more pleasant spots on the outskirts of England's metropolis [than Valley Fields]. One of its residents, a Major Flood-Smith, in the course of a letter to the South London Argus exposing the hellhounds of the local Rates and Taxes Department, once alluded to it as "a fragrant oasis." He gave the letter to his cook to mail, and she forgot it and found it three weeks later in a drawer and burned it, and the editor would never have printed it, anyway, it being diametrically opposed to the policy for which the Argus had always fearlessly stood, but--and this is the point we would stress--in using the words "fragrant oasis" the Major was dead right.

From Blotto, Twinks, and the Stars of the Silver Screen, by Simon Brett:

***
"When it comes to wicketkeeping, you're the absolute panda's panties."

***
Shopping wasn't really his length of banana.

***
"His name's professor Gervase Blunkett-Plunkett. He's the Egregious Professor of History at Oxford University."

From The Whistling Legs, by Roman McDougald:

***
"He's a nice little man, but I think he has an awful lot of imagination. All his reasons for believing anything are terribly complicated, and he counts them off on his fingers. He holds up one finger and says, 'Point 1'; and then, when he has explained that, he holds up another finger and says, 'Point 2.'"

[Later]
"Now!" Carlo [the "nice little man"] paused, and Cabot knew without seeing it that he had raised a forefinger in the darkness. "Point 1...."

***
"She sits there staring at me through those big glasses, and the glasses seem to get bigger and bigger."

***
"I want you to give me the dope on that in something flat."

***
"And Mr. Carlo Pugh....peering down into cupboards or drawers through a big round glass, like a man who was spying upon a pixy or sticking his nose into a leprechaun's business."

***
"Everything seems impossible before breakfast."
