I’m enjoying Carry On, Jeeves, a collection of Bertie Wooster short stories by P.G. Wodehouse. “Without The Option” is one of the best. At the end, when Jeeves explains the sublime way he vanquished the opponent, his victory depends on a gigantic coincidence.
To bring you up to speed, Bertie tries to help his friend Oliver (beholden to his Aunt Vera for 100% of his financial support) out of a romantic jam by suggesting he steal a policeman’s hat. A reasonable solution to most problems! Naturally, Oliver is thrown into jail for thirty days. If hair-trigger Aunt Vera finds out, she’ll cut him off forever. Disastrously high stakes! Bertie’s plan goes pear shaped and, at the worst possible time for it to happen, the worst possible thing happens — he finds himself in the same room with the dreaded Aunt Vera. There’s nothing to do but confess the truth…
Keep in mind that she’s a conservative, wealthy, frightening, ancient battleaxe and Bertie is terrified of the scorched-earth destruction she’ll wreak on his chum.
And now, the climax!
How does Jeeves save Bertie’s bacon? A cousin who’s a copper.
“There’s no way,” I mused, “this providential piece of good-luck-lightning could accidentally strike in a story written by someone as careful as Mr. Wodehouse.” I went back, looked, and there it was: an artfully placed, oh-so-useful set up, neatly tucked where we wouldn’t notice it, under a stack of socks.
Enjoy Wodehouse’s subtle set up! Know that Bertie has a crushing hangover…
As far as Jeeves’ eventual ability to solve Bertie’s problem, the fact that Jeeves has a cousin in the town where the opponent lives is the story’s most important piece of information. That set up is buried under the business of Bertie’s hangover pushing him to tell Jeeves not to interrupt. Jeeves interrupts anyway and Bertie chastises him. The instant the “cousin set up” appears, it is obscured by a scolding. The set up is, like a cat sleeping in a dark doorway for you to trip over at 2:00 a.m…. present, but invisible.
You can’t just willy nilly lob a cousin in at the finale and that cousin be the machinery that saves Bertie from Aunt Vera’s Doom. Deus ex machina works when you’re in fifth grade, but not in the summer following fifth grade or ever after.
Don’t give your character a magic sword at the moment they need it. Tuck it away it much, much earlier, hidden from view, in their underwear drawer.
