"Dame Rose Macaulay (1881-1958): Anglican Apologist"

‘“Take my camel, dear”, said my aunt Dot, as she climbed down from this animal on her return from High Mass.’ This may be the most famous opening sentence in twentieth-century Anglophone fiction, from the great Anglican novel The Towers of Trebizond (1956). John Betjeman and Trevor Huddleston called the book (approvingly) ‘Anglican Propaganda’. But is it? And was its author, Rose Macaulay, ‘an Anglican apologist’?
