15C sleuthing nuns aren’t everyone’s cup o’tea, but I just read such a book which was – put simply – well written.
Clean, unfussy writing combined with well drawn characters and a story which was period appropriate (without the usual silly contrivances of historical crime/mystery novels). With believable emotions and characters acting as you think they might have, in a story which felt simple but really had a lot of characters and things going on in it.
Not a book to win awards or be raved about in the press, but what good story-telling and good solid writing are all about.
I can’t promise you’ll like it, but worth a read just for analysis purposes, (unless you have an aversion to historical novels). “The Maiden’s Tale” by Margaret Frazer.
