This is a collection of three P.G. Wodehouse novels: Very Good, Jeeves (1930), Right Ho, Jeeves (1934); and Joy in the Morning (1947). There are 16 Jeeves & Wooster novels, although some of these are really story collections.
Wodehouse worked on a novel for up to two years, mostly writing a story treatment that outlined characters, plot elements, and funny scenes or jokes. He'd then take three to six months to actually write a novel based on this treatment.
Probably the best and weakest of the three novels in this collection is Very Good, Jeeves, a collection of 11 short stories (two-thirds of them written from September 1929 to April 1930) reworked into a novel format. It's the best of the three novels, in a way, because Wodehouse was much better as a short story author (in my opinion) than he was as a long-form novelist. His vapid high society fashion-plate, Bertie Wooster, is best taken in short doses, and the episodic nature of this "collected novel" works to the advantage of both character and plot. The "inimitable" butler, Jeeves, usually arrives on the page at the last second, instantly rights Bertie's ship, and departs with a wry smile. In a long-from novel, Jeeves often disappears, but in this "collected novel" Jeeves reappears at the end of each chapter. It feels more balanced. Yet, this "collected novel" is the weakest of the three, because it feels so vignette-y.
Right Ho, Jeeves is far and away the best of the novels in this collection. While there's less Jeeves, Bertie Wooster comes off much more balanced -- if dull-witted, and hence prone to comic failure -- and therefore much more readable and enjoyable than in either Very Good, Jeeves (where his idiocy is heightened for the short story) or in Joy in the Morning (more on that later). I found myself laughing out loud at Gussie Fink-Nottle's drunken awards speech, and no wonder: It's considered a masterpiece of comic literature. Like most of Wodehouse's writing, Right Ho, Jeeves is a comedy of errors. Misunderstandings, embarrassment that leads a character to misstate the truth or avoid speaking it, and the purposeful misunderstandings of (primarily) the female characters in order to manipulate men and get their way are piled on in the novel.
Joy in the Morning is inferior to the other two novels here. Wodehouse was working on it in 1940 in France when Nazi Germay invaded. Wodehouse dithered; for a week, as France collapsed, he neither sailed across the Channel for England nor fled south with his wife. He was captured on May 22, and imprisoned in various locales until June 21. Taken to Berlin, he agreed to make five humor broadcasts on Nazi radio. He was excoriated in Britian for this. Wodhouse remained in Berlin until September 1943, when he was allowed to return to Paris. He was in the city when it was liberated on in August 1944.
Wodehouse had been at work on Joy in the Morning when captured. He wrote Money in the Bank (a non-Jeeves novel) while in prison before going to Berlin. He finished Joy in the Morning while living in Berlin.
The novel suffers, I think, from not only being interrupted for two years (a serious break for Wodehouse and his working style) as well as from the circumstances under which it was written. Wodehouse, by all accounts, was as apolitical as anyone could be, and supremely ignorant about the political implications of what he did in Berlin. His broadcasts were funny, not propaganda, and managed to include subtle digs at his captors. But in wartime, there is nothing that is apolitical. And despite all the claims about how apolitical Wodehouse was, it beggars the imagination to see him as a naif who had no understanding of either Nazi politics or what war meant. If we accept the view that Wodehouse was a bonehead, it becomes hard to reconcile with his excellent writing. On the other hand, if one assumes that he understood what he was doing (broadcasting in order to improve his living conditions in Berlin) but willfully wished away the possible consequences, then I think we have to also come to the conclusion that it influences his writing in Joy in the Morning.
I think Joy in the Morning suffers. The plot is thin. Plot holes are painfully obvious. The chapters seem so episodic as to be disconnected. Jeeves is almost completely missing from the work, and certain humorous elements fall so flat that you can hear the "splat" as they do so.
Joy in the Morning is enjoyable, but certainly not, in my opinion, anywhere nearly as good as other Jeeves & Wooster novels.
