All three Christie covers, I should point out, are courtesy of the lovely Rachel; I don't own any Agatha Christies myself, but hey: what's hers – as in Rachel's, not Agatha's – is mine, although I'm not sure the reverse is necessarily true. You can see the covers in question below, along with back covers and cases/jacket flaps for reference, but I'm not quite done with Agatha Christie yet, nor P. M. Hubbard, nor indeed the subject of last week's posts, Desmond Cory. Because I'll shortly be adding yet more wrappers to Beautiful British Book Jacket Design, including a Christie jacket by a designer who's already made it into the gallery, plus some children's novels, and more besides...
