This year I have to read Gaudy Night, because as I started with Busman's Honeymoon, it's the last of the Wimsey's for me, which makes me sad, for some reason.
Have you also read the two Jill Paton Walsh books - she finishes off an uncompleted Sayers ('Thrones, Dominations') and adapts some letters into another novel (whose name escapes me).

Do try some Belgian choccy while you're over here.

PS I've friended you back, if that's OK.
