Dorothy L. Sayers: Clouds of Witness

Last night, I finished the second Lord Peter Wimsey book, Clouds of Witness, and I very much enjoyed it.  Sayers is really quite a good writer, and although Lord Peter can get a little annoying at times, I basically like him as a character.  But here's what's interesting to me, at least at the moment:  Lord Peter is written as a modern, secular kind of guy, but Parker, the police inspector guy that Lord Peter runs around with, is all Christiany and traditional.  Inspector Parker reads commentaries on the New Testament as his bed time reading.  Now none of this is particularly interesting in and of itself, necessarily.  But here's the interesting piece:  Sayers herself was very vocal and "out" about her own Christianity.  She was certainly a scholar and an academic and a writer, and she made it clear that her beliefs and her faith motivated her work and informed her understanding of the world.  So, here's the thing:  in many ways, the middle-class, conservative, seemingly-Christian Parker would seem to be more like Sayers herself than is Lord Peter.  And I don't know what to make of this.  And I understand Peter's social class; after all, who doesn't want to read about a quirky member of the Peerage?  But why make Peter so markedly secular, especially in light of Parker's presence in the books.  I don't know where I'm going with the whole thing, but it seems somehow unexpected.
