There are 14 Jeeves books, and I am given to understand that they are all fairly similar. Having said that, its not necessaily a bad thing, especially when you consider the various Jeeves stories were published over a span in excess of 50 years. Certainly the two books I have read are quite similar, but then again, I still like vanilla ice-cream after all these years too.
Firstly, this is a "novel" only in the loosest sense - it is more a collection of linked short stories, in chronological order, where earlier events may be referenced but are usually not actually critical to the tale being told. The stories are the "adventures", I suppose of a Mr Bertram Wooster, a gentleman of the 1920's with a large private income, Eton and Oxford, and his valet, Jeeves. Mr Wooster's troubles usually revolve around a family member, a young woman to whom he or one of his friends becomes betrothed, or both. Jeeves provides the solution to whatever problem is at hand, regularly astonishing his "intellectually negligible" employer with his aptitude.
These stories are great fun, for all that they are gentle and inoffensive. If you wished, I am sure you could deconstruct this on any number of levels: but why not just read it for enjoyment instead? This is almost the definition of a "simple pleasure", with beautiful language and wonderful dialogue. Its almost a very clever sitcom in book form, and in fact was filmed for TV some time ago now with no less than Hugh Laurie and Stephen Fry in the roles. I have not seen that series - and am glad of it, since it would jar a first reading of the books - but it is nice to know that that is out there somewhere too.
