Browsing my local Oxfam, my eye was drawn to a faded hardcover with the title The Merry Wives of Westminster. As some readers may know, my Twitter handle is @WestminsterWAG, so I bought it for the princely sum of £2.99. It wasn’t until I got home and started reading it that I realised who the author was: Marie Belloc, sister of Hilaire, a successful novelist in her own right.
