A Prefect's Uncle was P.G. Wodehouse's second novel, published way back in 1903 when he was in his very early twenties. It followed The Pothunters, which hit shelves the year before. I can't find any indication that it was originally serialized, as Pothunters was, but it feels like a serialization, and it looks like all of Wodehouse's early school stories were originally published in magazines such as the obviously named Public School Magazine.
Pothunters was a small thing, a book clearly assembled from parts, but it was fun and amusing, full of characters who sounded real and inhabited a real world, and it had a plot that meandered but did, more or less, circle the missing trophy alluded to in the title. I don't want to claim a lot for it, but it was a solid genre exercise - in a genre that's been dead for a hundred years now, admittedly, and never was popular on my side of the Atlantic to begin with - and it showed that this Wodehouse fellow was someone to keep an eye on, who could do good things and probably would.
Prefect's Uncle is the same sort of thing, but down a notch or two in most areas. The central plot is not really about the uncle of the central prefect; it's more a sequence of mostly cricket matches, told in very detailed language that I have to imagine would be smashing fun for someone who actually understands how cricket works. From my seat, I can say it all sounds impressive, and that Wodehouse describes the action of the matches well, with a deep facility at drama and knowledge of cricket terminology and tactics, even if it all just turns into a wall of random words to me.
Our central character is Alan "Bishop" Gethryn, head prefect of Leicester's house at the fictional Beckford public school. He's seventeen or so, near the end of his schooling, smart and upright and full of all of the traditional English public-school virtues. Bishop meets two new students in quick succession: first is his new fag (yes, yes, I know - it was a very different era and the usage of that word has shifted quite a lot) Percy Wilson, who is true and smart and good and rather boring and plays very little part in the novel. Next is Bishop's uncle, who he has to meet at the station. He thinks this is a conventional uncle: a generation older, with luck open-handed with the pocket-money and not too tedious with the advice. But it is actually a younger boy, one Reginald Farnie, who has been kicked out of three well-known public schools already, and is the kind of terror Wodehouse would get a lot of mileage out of later in his career.
As it is, though, Farnie doesn't do a whole lot here, though he does cause Bishop to miss a very important cricket match - which Bishop cannot explain to anyone, for the usual vague and unclear stiff-upper-lip reasons - and that means Bishop loses his place on the school's cricket team after they lose that very important match to a rival school. But Bishop is still captain of his house's team, so there's more planning and training and detailed descriptions of inter-house matches and a muddled rebellion by some of the "bad boys" of that house, who Bishop kicks off the team and replaces with very junior boys.
Again, there's a lot of cricket in this book. I think it's told well, and could be gripping to a reader who understands what's happening. For me, though, it was largely a sequence of baroque technical terms about kinds of bowling and where balls are being hit and how wet and/or sticky the particular ground was that day. Wodehouse also includes a certain amount of "well, this match is against that village, and they have a couple of ringers from this county team, so it's semi-important, but the next one is against Rival School, so it is of earth-shattering importance, and then there's the inter-house play, of which only these three houses are important, for reasons I will detail at great length". So I did the names-in-Russian-novels thing and mostly hummed through the cricket matches, which are roughly 40% of the novel by weight.
If you want to read a really early Wodehouse novel, to see how he did school stories, I recommend Pothunters. If you know how cricket works, you could try this one instead, but be sure you really do know how cricket works. It will test that knowledge very strongly.
