A Series I Wish Had One More Book in It

This week's Long & Short Reviews prompt is "a series I wish had one more book in it." 

Lydia Schoch made a particularly interesting case for the Narnia series. C.S. Lewis wrote seven books that illustrated points of Christian belief through adventure stories written for children, though adults seem to like them as much as or more than children do. As a throwaway line, at the end of the last book, he mentions that one of the English children who visited Narnia was "no longer a friend of Narnia" and thus missed being killed in an accident in England and going to the Narnian part of Heaven. Susan had become too fully engaged with social life in England to want to reminisce about Narnia with her siblings.

So, is Susan lost, because Narnia was where her siblings had their early encounters with the spiritual dimension of life? Or, is she saved, as everyone else in the children's fictional version of England can be saved, by faith in Christ that will allow her to live a long and good life in England? She seemed to deserve the latter. But...but...the story, or stories, of her life in postwar Britain wouldn't be Narnia stories. They wouldn't even be children's stories. They'd be stories that Helen Joy Davidman Lewis could have written if she'd lived longer, but C.S. Lewis could not.

I'm not generally inclined to write or read fanfiction, in which other writers try to continue a series. The seams always show. Series like Nancy Drew, the Hardy Boys, the Bobbsey Twins, etc., that were written by different people under one pseudonym, were cheaply done in the beginning and are amusing in their discontinuity. Series like the Oz books, which began with an individual's inspiration, didn't hold up so well under the process of posthumous serialization. I appreciated the fact that a couple of Holmes fans who thought they could write successors to Arthur Conan Doyle's work chose to write about Mycroft Holmes' very different life from Sherlock's, but the better they did that, the better they succeeded in creating a different atmosphere for a different character that had limited appeal to Sherlock Holmes fans.

So there's one series that I've read that I really wished had one more book in it. P.G. Wodehouse's Blandngs Castle series wasn't really a serial story so much as the setting for a lot of variations on the basic romantic comedy plot. There wasn't a particular character readers really wanted to see more of; there was the Earl of Blandings, a dotty old chap, and about a dozen of his younger siblings, all now old people too, with children and sometimes grandchildren who were always coming to Blandings Castle, usually hoping for money to get married on, and having comic misadventures in which glass got broken, animals got stolen, and nice but irresponsible people got arrested but were always out of jail at the end, and usually at least two young idjits were married to each other. Readers knew each story was only meant to be something to laugh at, and so they all were. 

Except the last one. At ninety-three, P.G. Wodehouse knew he might or might not live to finish writing a novel that was published as Sunset at Blandings. He outlined it in some detail and wrote a first draft of about half of it. He had made it possible for his heirs to publish the draft, with some explanatory notes about his last days. So they did. It sold. But Sunset at Blandings wasn't nearly as funny as readers knew it would have been when Wodehouse finished it, if he'd only lived so long.

I wish Wodehouse had had time to write the novel he intended the last Blandings Castle story to be.
